This is painful. They got a used solder mask holder, a Lumen pick and place machine, a bunch of old Siemens feeders, and a small automatic reflow oven. All these tools needed major work. Everything with firmware needed firmware mods. Everything else needed assembly or major cleaning. Everything needed adjustment. They had to 3D print their own solder paste squeegee. They're six months in and still trying to produce one simple board.

I've been down this road of populating a surface mount board. There is a minimum size for a practical board-stuffing operation, and they are below it. They are using prototype techniques for 100 units or so, not techniques that scale.

Surface mount soldering requires applying hot air in a very controlled way, with the temperature ramping up, holding at the high temp for a few seconds, and then ramping down. On a small scale, you have a programmable oven which tries to do that. Those always have heat distribution problems. For production, you have a tunnel oven, with about six sections at different temperatures and a chain conveyor to take the boards through the tunnel. With the tunnel oven, you let the whole thing warm up and stabilize, and when all zones are at the right temperature, you can repeatably solder boards successfully.

They're using a hobbyist-grade pick and place machine. Slow, but cheap. Plus the software isn't ready for prime time. They looked at a used production machine. Runs Windows XP and wouldn't fit through the door. Rejected that.

They're about EUR 30,000 into this, not counting their own labor. This approach is not going to revive electronics in Europe.

Learning by mistake isn't painful; it is how you learn best. I keep iterating on that point to my children. But that isn't merely what these guys were doing. They were doing more, since they were documenting their (expensive!) learning process. Documenting your learning process and sharing it freely is allowing others to not make the very same mistakes, but to do better instead. It lowers the barrier of entry for competition, taunting competition who hopefully also share back. Like many talks on 39c3 (esp. the lightning talks), it is an invitation to collaboration.

Sharing the documentation is also an act of compassion, and very much in the spirit of FOSS & OSHW.

This talk was hands down my favourite talk (and not even in a subject I am familiar with!). These two guys shared a lot of info in little time, and were very humble. It was also a presentation which contains a political component (Europe's lack of independence, specifically hardware-wise), but it managed to avoid that discussion. Why, because it is assumed the attending public shares the same value. Instead, it maintains focus on the taking action part. I am not sure everyone here shares said value, but I do, and for whatever it is worth: USA is in a similar boat.

Hey! Talk speaker here, thank you so much for these words.

This is exactly what we wanted to convey: Let's act, our way isnt the best way, but it is the path we're on, and there is little we can do on our own to get to another path.

We don't want to build the european JLCPCB, we don't even know what our company will be in 20 years if it still exists.

What we want is to give knowledge and see more people get into the business of electronics. We also want to give meaningfull jobs to engineers and factory workers which will eventually join us.

We are not going to change the world, I would settle for selling 1 unit of 1 well made product to 1 customer. I would settle for giving one person a job that they love working with cool guys to make electronics. I would settle for the ability to pay my rent from this, from bringing value in the world.

markus_zhang26 days ago

Just curious, is it possible to get some basic production "kit" from China and go from there? I'd assume it's going to be new and cheaper and more "modular", and you only rely them on these basic items. I have never been into electronics manufacturing so not sure if it makes sense.

napkinartist26 days ago

You are saying the same thing they said -- it doesn't scale. It's not how you build a large factory. They acknowledge this and pretty quickly move on to say that they are aiming for smaller and sustainable.

They even specifically call out why they chose not to use a conveyor based oven in the video.

Basically they believe they can be price reasonable at small scales, small batches. Build process knowledge and expertise over time, and then incrementally scale up after assessing bottlenecks.

I think the route of local sustainable, grow as needed or collaborate to expand capacity is pretty reasonable.

Animats26 days ago

It's not possible to make a competitively priced product that way. What are you going to do, sell artisanal circuit boards on Etsy?

Here's a small US-based PCB board and assembly facility in the US, in Hesperia, California.[1] Looks like it might have 20 to 30 employees from the building picture. This is probably about as small as a viable business of this type gets. It doesn't have to be done in a huge plant like JLCPCB in Shenzhen.

Here's a company in India, Invariance, which makes low-cost semi-automatic machines to do exactly the same operations 39c3 is doing.[2] They have three machines - a solder paste spreader, a pick and place machine, and a mini tunnel reflow oven. They make all three machines. These machines intended for small companies who want to assemble their own boards in house. The solder paste spreader is just automated enough to do a consistent job, with pressure and timing controlled. The pick and place machine uses their own feeder design which runs off strips of component tape. The tunnel oven is small, only about a meter long.

That's close to a viable minimum production solution.

39c3 is the conference it is being presented at, not the presenter. 39th Chaos Communication Congress, the annual conference of the Chaos Computer Club.

This is a hacker messing around who is presenting to inspire others and get feedback. Many things presented at Xc3 are wildly impractical, potentially illegal, or not even technical at all and more on the side of activism and policy. Most are interesting and fun, which is the main goal.

crote26 days ago

That depends on your definition of "competitive", doesn't it?

Being 3x as expensive as China but 0.1x as expensive as current small-scale EU manufacturing can be extremely competitive. Plenty of people looking for <1000 unit runs would be willing to pay extra for a "made in EU" label.

mapt26 days ago

COVID and the supply chain crisis made apparent just how over-reliant we are on Shenzhen and Taiwan for the most basic components. There are several hundred ICs on dozens of circuitboards in every car now that are dumber, slower, and less efficient than a 1990s calculator, that we have lost the ability to produce domestically. These are now bottlenecks to manufacturing in any disruption to world trade.

It doesn't need to be cutting edge, if you have a few board assembly shops and some fabs pumping out small chips in 20-30 year old process nodes it helps the resilience of the economy and geopolitical situation a great deal.

Hey, I'm one of the two speakers :)

The commenter above you phrased it well: "Price-reasonable", to us, it's first about breaking even.

I will look into the companies you linked, looks interesting!

Though to give you food for though, I will tell you about a french drone manufacturing company, they manufacture in house, they turn over probably around 10 million € a year.

I know first hand they stencil print around 10k boards a year using a "machine" that is 2x4's from the hardware store, and a credit card :)

10 years ago in the US I met someone who owned a company of about 5 people that he largely built off of the acquisition of a single broken pick-and-place machine which he repaired himself. They applied the solder paste manually and finished the boards in what looked like a toaster-oven. Each production run consisted of around 100 units which were sold at $50 apiece. The company is still in business today, as far as I'm aware.

Design for manufacturability means you leave tolerance within Factory limits, and your own prototyping process limits.

While an inexpensive PnP machine will do 50k to 80k components/hour. If you have someone doing _any_ task, than add $3 USD * number of operations per unit.

Tech is a low-margin business with a lot of regulations, and should be contracted to a proper facility if making over a few thousand units a month. Tooling up for a production line is almost always a bad idea, as it usually adds additional barriers to a product launch as people get sidetracked. =3

Electronics in Europe is so dead. It is past the point where where it can be revived. One thing is sick overregulation to spin hardware product. Last nail in the coffin today is Cyber Resilience Act. It dwarfs all the regulations before it.

Second thing is talent. People can’t hardware anymore. I mean putting a 0402 capacitor on the printed circuit board is not hard. But doing that in meaningful way gets hard. As a contractor I designed few boards and optimized for production in China. In my dayjob colleagues are stuck in the last century. No recent knowledge about parts, design rules, testing principles… No willingness to learn and talk to Chinese manufacturers about optimization. Just copy paste bad decisions from old boards to new designs.

Honestly I wouldn’t even try to revive anything in Europe. Chinese electronics factories are way too far in the future. The suppliers for my workplace are all stuck in the past. Even the ones with new equipment struggle to use full potential due to worker’s shortage. Which is probably a problem in whole western world. Who wants to be manufacturing technician when you can be lifestyle influencer!?

abielefeld26 days ago

Hi, Augustin here, one of the presenters.

As other commenters pointed out, the electronics industry is quite big in Europe, on paper it generates a lot of money and sustains a lot of jobs. The issue is a bit more complex, and you point it out when you say people around you are old and old-fashioned.

Like I said in the talk: We used to laugh at the chinese products for how low quality they were 20 years ago, who's laughing now?

I don't believe europeans are unable to turn around this situation in as many years as a matter of fact, it's my core beliefs: That together with other young motivated people we'll build our own little electronics industry for ourselves, among ourselves and people who believe we can one day have theye crazy future factories in Europe.

Yes it's crazy hard, but like you I believe things will get sufficiently bad that more will see that the effort is worth it.

You should check out the 39c3 talk from Kliment, he understands this issue so well, and I'll paraphrase him here: Electronics is dominated by old dudes, the industry is hostile to newcomers, self-taught people, women, and more. But by making an effort to give people who are starting a good experience, we can turn this around.

Honestly there is no worker shortage, in my immediate contacts, I already know 2 or 3 people who are ready to work my production line: They have the smarts, skills, and time. They are unemployed because no one would respect them, and give them a meaningful mission like we would, and it's quite clear this is quite a widespread feeling among people.

Yes but they make up with via immigration of candidates on visa. Last time I worked in semi, about 30% of colleagues were on visa from abroad. Today from former collogues still there, I hear it's close to 50%.

joe_mamba25 days ago

>I don't believe europeans are unable to turn around this situation in as many years as a matter of fact, it's my core beliefs

Actually, I DO believe we are unable to turn it around. I've done EE work both in Europe and in China for over a span of 10 years, and what sets China apart from Europe that enabled them to overtake us is the mindset, both at government support level AND at individual level.

Chinese operated a lot closer in mentality of the US compared to Europeans, as in very cutthroat move fast and break things, wanting to ship a new product every 6 months(!). This mentality is lacking in Europe who mostly stick to slow paced industries where there's a national security, regulatory or bureaucratic moat like aerospace, defense, telco, industrial automation or automotive, but nothing cutting edge in consumer space that's dominated by China, Korea, Japan and US.

Then there's the massive investments and support from the Chinese state that's missing in European electronics industry. To get an idea compare to the massive sums Europe invests in pharma(or life sciences) versus pitiful investments in electronics for example, and you'll get what I mean.

Until those change, we have no chance, we're just dreaming and huffing copium that somehow things will magically improve out of the blue.

>the industry is hostile to newcomers, self-taught people, women, and more.

Pretty much this, minus the hostility towards women part. I've had few women colleagues everywhere I worked in EE, there's no gender hostility or discrimination, just that young girls looking for a career, aren't really into sitting hunched down over a table and soldering and probing PCB's in a lab somewhere in a techo-park in the outskirts of town as a career, when stuff like HR, marketing, brand design in the city center, is way more hip and appealing to young urbanites. You can't force people to be attracted to a specific industry or line of work. Similarly how there's not much women in construction, welding, oil industry, fire fighters, LEO, etc and it's also not due to hostility, or how there's not too many men in nursing, HR or childcare.

> They are unemployed because no one would respect them, and give them a meaningful mission like we would

I hope you realize, you're not really selling the European electronics industry optimism here with this example of skilled people being passed on for employment.

I am afraid, that when it gets too bad and too obvious it will be too late.

For me first steps would be turning bureaucratic ship around and making regulatory framework simpler and cheaper. With some exceptions for startups/small companies during very first months or years. The industry would be more attractive and with more demand for European electronics manufacturing. With more demand it would slowly start growing domestically. It’s insane that the rules for my 1 person company are the same as for Bosch or Siemens. I can praise good lobbyists work. There are two engineers at my dayjob that are writing mandatory documents about cadmium amount in screws or calculating sustainability parameters…

abielefeld26 days ago

This is happening already! The 28th regime (https://www.europarl.europa.eu/committees/en/the-28th-regime...) will simplify the framework to register and operate companies in the EU, also the push by the EU commission to implement the Draghi report (https://commission.europa.eu/topics/competitiveness/draghi-r...) is one of deregularization of the industry.

Of course quasi monopolies of European industry are hoping to lobby these measures to suit them more than small players, but I am hopeful, as we have some very good legislators and politicians who are on our side.

Also Eurostack (of which Eilbek Research is a member) is a lobbyist group pushing for Draghi-adjacent policies, most of all: Relocating the entire cloud stack to Europe. And while for the bigger members of this organization it means having our own Google or Facebook (including their harms), it cannot help but inadvertently push the EU to pass laws that will further the agenda of eroding the USA-Tech monopolies.

Cory Doctorow pushes this narrative (https://pluralistic.net/2025/10/15/freedom-of-movement/) that this can only be a benefit in the medium term.

Things are moving in the right direction, not many are talking about it, but when things hit mainstream news, they're already old by the reality's standard.

crote26 days ago

The regulations argument is a red herring: those mostly apply to electronics products sold in the EU, not manufactured in the EU. You have exactly the same burden trying to sell CN-manufactured hardware in the EU.

Worker's shortage is a real problem in China as well. Their approach? Automate everything. Focus on manufacturing 1000s of designs using a handful of standard formulas, instead of treating every design as bespoke. There's no reason this couldn't be done in the EU.

It's going to require a serious cultural shift, but given the right incentive I see no reason why it would be impossible.

pjc5026 days ago

> You have exactly the same burden trying to sell CN-manufactured hardware in the EU.

Not if you're a Chinese OEM: you just mail it in, and thanks to the arcane operation of international postage it's cheaper to post to Germany from China than from Germany. CE is such a European type of regulation, there's almost no enforcement, while at the same time it's so vague that simply working out what directives you might need to comply with is time-consuming.

Mind you as others have pointed out, there is still EU electronics. It's just not massive production runs for consumer electronics, much more of it is for defence, aerospace, and medical. And a bit of automotive, although that is definitely going to fall to Chinese car OEMs.

crote26 days ago

The problem is the gap between hobbyist project and hundred-thousand-unit production run.

You can't easily and cheaply get 10, 100, or 1000 units manufactured in the EU the way you can in China. This pretty much kills hardware startups and scaleups wanting to do local manufacturing.

If you're not a multinational or have an essentially-unlimited budget for your small-scale run, you have to outsource it to China.

>Who wants to be manufacturing technician when you can be lifestyle influencer!?

Before influencers people wanted to be actors. It predates the time before Electronics was 'lost' in Europe so thats not a convincing argument.

What you are saying really is that the world enjoys what we have on the backs of inadequately paid production engineers in China. As their demographic crisis does not produce a similar sized replacement generation, that benefit will go away as experts retire and no one replaces them. So one way or another wages will go up meaning inflation will go up and some of those 'lifestyle influencers' will now consider the field because it is a viable career path in terms of pay.

abielefeld26 days ago

What is really interesting is that worker pay in tier 1 cities in China (e.g. Shenzen) actually is higher than in EU countries such as Slovenia, Bulgaria or Czech republic. Incidentally these countries have a large number of EMS, and we know of quite a few startups that quickly grew production capability to be able to provide electronics assembly.

rangestransform25 days ago

Kids in china also want to be lifestyle influencers instead of manufacturing technicians

nebula880425 days ago

Yeah I didn't say that Chinese people didn't want to go down the same route, infact lifestyle influencers have a better shot there (probably 0.1% better).

There is so much overproduction of engineers that you are possibly working a customer support role with that degree.

Another reason SASS supposedly never took off there, why pay some company when you can just hire from the batch of overproduced STEM graduates and make any software you need.

When I can have an experienced engineer correct my garbage designs for free as part of a manufacturing service you know I am benefiting off of a lucky circumstance that will go away one day: https://youtu.be/ljOoGyCso8s?t=98

Joel_Mckay26 days ago

Not sure why your post was buried. As the EU does have a lot of rules, but if a product is reasonably made its almost the same cost as the US market entry. Robert Feranec covers a lot of the more obscure EU rules:

Designs that contain China parts are often immediately disqualified from most trade exemptions. The landed cost can bump gadget retail prices too high in some countries. YMMV =3

To be more specific: PCB manufacture anywhere other than China is, given the current economics, so dead. This includes the USA. The only viable alternative is SE asian countries (e.g. Malaysia) but that's not at a comparable scale. The reason is simply economics (e.g. labour costs, equipment, etc).

Hobbyist vapour phase reflow ovens exist although not cheap: https://eleshop.eu/vaporflow-275-vapour-phase-reflow-oven.ht...

abielefeld26 days ago

Hi! Augustin here, one of the presenters of the talk: Alex actually built a vapour phase soldering oven from scratch a few years ago! Indeed they are not exactly practical for series production, though they are amazing for small runs of very challenging to solder board though.

Main issues is solvent recovery: as another commenter pointed out, Galden is very expensive, and it is also extremely greenhouse inducing and we were not confident in our ability to recover it completely, especially at "scale" (100 boards per month or so).

In our case, we picked a hot-air convection oven, which, while not as good as VPS, is still a lot better than IR at not burning components. Our main challenge is always space, so we went for a production batch oven which already has more throughput than we need for us to get to profitability.

The plan is to upgrade to a long and big conveyor oven once we move to a bigger facility, these are quite cheap and they are compatible with a fully automated production line.

Yes this makes CCC look bad. You can tell they were not serious because they used OpenPNP. From the video - "most importantly, it is open, hackable, and extensible." not mentioned: able to assemble electronics!

abielefeld26 days ago

Hi, talk speaker here, we are hoping to assemble our first products this year.

OpenPnP is currently more than able to assemble electronics, Opulo and LumenPnP are used by many profitable companies (many I know first hand).

Our opinion (shared in the talk) is that there is a little bit of work to bring it from "able to assemble electronics" to "entreprise-ready" in the sense of adding features like access rights (operators and admins shoudl have different rights) and integration to Inventree, our inventory and parts management software.

Investing in even new production devices is a dead end, and our vision is that owning 100% of the software is owning 100% of the capability. China essentially developed their solutions themselves, and I believe that is the reason why they are so advanced.

Entire business needs are locked behind aging software, licensing hell, an junk fees, both in europe and the US.

Given the context (CCC) I would find it far less interesting if they did NOT use OpenPNP. It is also, coincidentally, able to assemble PCBs, even if it's perhaps not the best software out there.

Given it's CCC, a hobbyist hacker con, OpenPNP and especially those three things you mentioned seem perfect, I'm not sure why you'd think it makes the con look bad. I've heard this talk mentioned repeatedly as one of the coolest ones there, and I certainly enjoyed it myself.

It's not an industry seminar on how to start a board house, it's two guys explaining how they automated the basics of production on a low budget and with space constraints, etc.

"This approach is not going to revive electronics in Europe."

Revive what exactly? There's ASML, IMEC and many others. Then a host of PCB fabs that are expensive but are present and perfectly useful such as Eurocircuits and many others. This project is typical of these conferences where people find it interesting and fun to do things from scratch.

Given the economics, it is not possible for anywhere other than a couple of south east asian countries to be competitive at scale with Chinese manufacturers. This presentation hasn't a hope of replacing that using the methods outlined but it doesn't mean its a waste of time!

atwrk26 days ago

The comments here seem to show a typical US-EU divide in perspectives, people talk past each other. Yes, mass-market low-margin consumer products (the US view) probably won't be produced much in the EU in the next few years.

But much of the electronics industry in the EU is B2B and centers around producing high-margin products where 10.000 units of a product would be huge.

The company I work for, for example, usually produces a few hundred units of a product before the next revision replaces it. Whether or not the PCB costs 20€ more or not really isn't that important if you only plan to sell 100 devices of it per year for 10k€ each. Aspects like quality and regulatory conformity are way more important here.

grumbelbart226 days ago

That is an excellent point. The development costs of such low-volume projects are often way higher than the production costs. Having production in house or close often allows tighter, thus faster, prototyping and feedback during development, which in turn saves money.

The whole "But how can this be scaled and monetized" crowd here also does not seem to understand the point of such projects and Germany's Hacker community. It is about learning and just doing it, much less about building a high–revenue business.

abielefeld25 days ago

I think so too, because the bar to economic sustainability is not incredibly high. I know a lot of one-man businesses operating with one Siplace pick and place machine and making a good living out of it.

Many people don't have the desire to expand forever. In my case I hope the company grows o 20 or 30 employees, and then I would work stabilizing it so it can last 50+ years. e.g. setting up a trust to oversee the well being of employees, the quality of the products, etc.

This is completely alien to most american founders and businessmen, in the words of Larry Elison: "it's not enough for me to win, it's about everybody else losing"

abielefeld25 days ago

Hey, talk speaker here, that's a great point!

A discussion that got cut from the talk at the early draft process was defining what "small-series" and "large-series" mean.

To me, at a human scale and without dystopian monopolies, a small series is anything under 1k, a medium series around 50k and a large series 100-500k.

I wanted to define a special class of series, because to an american a small series is probably more like 100k, and a large one 1 million or more, last year something like 230 million iphones were sold globally and that's an absurd number imo.

Because my vision of a healthy electronics industry is 200 companies each selling competing runs of 1 million units, rather than apple selling all 230 million.

In my ideal world then, the only way for apps to be distributed is a marketplace that is regulated and prevents apple from imposing their 30% tax on every dollar spent on the app store.

How would this marketplace be regulated? Is the idea that there would be an open app format (so that devices from different vendors could run these apps) or a regulated OS?

If you're interested in assembling PCBs at home, but you're looking at all this expensive hardware and thinking it's impossible, I've had great success with:

  1. Stencil jig: two bare boards taped to stiff cardboard (the kind stencils are shipped in)
  2. Squeegee: an old debit card
  3. Pick and place: ESD tweezers, a magnifying glass, and some tunes
  4. Reflow: a toaster oven modified with a kit (the expensive part: https://whizoo.com/products/controleo3-reflow-oven-build-kit)
I've made tons of boards with this setup and they work great. Are there limitations? Sure. Doing pick-and-place by hand will set a lower bound on the size of components you can design with. It also forces you to keep your part count down (but you should probably be doing that anyway). For my projects, these are never even close to the biggest problems.
ProllyInfamous25 days ago

I've been an early employee at two separate small-scale US manufacturing facilities, each making only a few hundred products annually ($x,xxx, each). Their PCBs contain several hundred components, mostly surface-mounted.

Making PCBs outside of SE Asia is not economical. You cannot afford to train labor on such a small scale, and would be foolish to manufacture more than a few of your own prototype boards.

>2. Squeegee: an old debit card

This works really well

>3. Pick and place

Even with a cheaper optical pick-&-place, you still need to examine every board thoroughly (the placements aren't optimal).

>4. Reflow: a toaster oven w/ mods

The problem with this approach is that the low thermal mass of a toaster oven results in inconsistent temperature profiles (e.g. sporadically burnt / un-soldered). I have used this setup and much prefer a larger reflow oven (with conveyer).

----

A repeated problem with this in-house PCB manufacturing dream is that the EE designer the circuit board cannot work more profitably when he has to make all the PCBs himself — which he'll have to, because he also cannot afford most American training/labor to make reliable boards.

Oh, I would never recommend my setup for assembly of actual products. I've spent enough time in avionics to know where that line is. :) My "lab" is strictly for side projects.

What I really would love is a JLCPCB equivalent in Europe. Slightly higher prices are OK, but I want to have the the Same amount of process automation and flexibility. Should be good for a scale of a few thousend per year.

Hi! Have you every checked out aisler.net? In my opinion they do an amazing job, it's not quite JLCPCB prices, but maybe only 20% higher depending on what service you take, and they deliver faster since they are based in europe.

Their business model is pooling small orders and sending them to board fabs in europe, mainly germany and some in the east.

> maybe only 20% higher depending on what service you take

For higher-end board that seems likely. For cheap hobby-grade boards just the job fee[1] is more than 10 boards delivered is from JLCPCB.

That said, thanks for reminding me. Will definitely compare next time I need boards.

The job fee seems to include shipping, which makes it more reasonable. But Aisler's "estimated dispatch" for the budget service is Jan 26. That's 10 business days + shipping, making it not very competitive with JLCPCB's 10-15 business days including the slowest/cheapest shipping.

Express service adds ~20 EUR, roughly the same cost as picking DHL express delivery on JLCPCB.

Just checked myself using a board I already had manufactured, and can confirm it's a lot higher than JLCPCB or PCBWay.

Maybe for rapid prototyping it is okay, but at scale, to make one board is more than the entire selling point of the whole device.

Aisler is decent for bare boards, but their PCBA is several orders of magnitude more expensive due to the setup & handling fees. JLCPCB has this down to a science, with their preloaded (and therefore dirt-cheap) "basic parts" and pre-approved "extended parts" pulled directly from LCSC for a small fee.

On top of that they also offer 3D printing, CNC machining, sheet metal bending, and even a McMaster-Carr-like parts store. It is literally a one-stop-shop for all your hardware prototype needs.

Have you looked at Eurocircuits? Not quite as big, but similar kind of thing.

magicalhippo26 days ago

Similar in how you order, not similar in price at all. Order of magnitude more expensive for hobby-grade boards.

Thank you for the hint. I tried but the pricing is a bit disappointing. I started with an LTE modem mini-PCIe card that contains a modem module and some simple components (coils, a voltage regulator, U.FL connector).

The offer from JLC for 1500 pieces (without the modem module) was 2000€ + Tax + Shipping, so way less than 3000€.

The comparable best offer from Eurocircuits was 11000€, so a factor of 4.

JLC can even be optimized further (e.g. panelizing, daves another 500€).

I hoped that I can produce here in europe with a maximum price factor of 2 in comparison to JLC which seems not be possible. It's cheaper for us to employ someone who manages JLC than producing in europe - especially when going to mass production.

Eurocircuits does the same kind of service (bar the parts library) but has the DRC - but you aren't going to get slightly higher from anyone in Europe

crote26 days ago

The parts library has a massive value.

For a lot of parts the exact details aren't crucial. If I'm using 4k7 0603 I2C pullup resistors I'm more than happy to swap them for 5k6 0402 if they just so happen to have a reel of those lying around and it means not having to wait two days for a restock.

Same with plenty of other parts. Maybe 10% is crucial, the rest can relatively easily be swapped out with whatever happens to be available. Transistor from a different manufacturer, generic level converter with two extra channels, LDO in a different package? If I know what is available, for a proto run I'm more than happy to make a few small changes!

I have been using them in the past, when I needed a board overnight. Problem is that they are prohibitively expensive. For the price of a couple of bare unpopulated boards I could get dozen boards populated (with parts priced in) from China and they would arrive at the same time. Once Brexit was fully implemented their shipping was slower than from China, so they lost all edges to me.

It's impressive how JLCPCB somehow made this process seem so seamless and easy for PCBs but also for other random components one might want.

Recently needed an 4 adapters in sheet metal for a project, two fabrication shops near me quoted >100$. Got JLCPCB to do them all for 12$ with 20$ of shipping. Got them in less than 2 weeks.

I used a Voltera V-One for a few small projects that otherwise would have been breadboarded, and it wasn't bad.

This is the approach we're taking at Pikkolo! (pikkoloassembly.com).

Heavy focus on low-capex and machines we can easily scale and hack up specifically for high-mix/low-volume work.

Hey! Don't hesitate to get in touch with us, I read your website but there isnt so much information yet, but Alex and I would love to hear more :)

jacquesm24 days ago

What I really loved about the talk is that you got a good insight into the actual complexities of manufacturing and drew all the right conclusions from it, rather than to throw your hands up and ordering stuff from China after all.

Friends of mine - with a bit more practical experience - are doing something similar, they realize that if there ever is a real demand for their product it might be at a time when the cheap alternatives simply are no longer available and have set up from day #1 to do everything in Europe. They are - like you - quite talented but the difference is that they have access to a lot more funding and if they need a particular machine they will simply go get it rather than to make their own.

You are resource constrained and that brings out a lot of creativity, which in the longer term will turn into a competitive advantage.

This was a wonderful talk. Thank you for sharing.

Everything John Nagle said is true. But to have a meaningful discussion about it on HN is futile because we need to come together and first admit and agree that exporting everything to China has ruined the economy and culture in the West. That isn’t happening. The best we can do is remind ourselves to follow the guidelines while we get downvoted by brigades.

I watched the video and sent it to family members who are deeply involved and ve$ted in manufacturing in the West. These two boys are unlikely to see anything like this at scale in Europe. That ship has sailed while no one was looking, and it’s not coming back.

Major multi-decade fuckup.
