It’s tricky to compete with your own suppliers. For example, see Microsoft’s dance with Dell & HP when they launched Surface. How do you plan to keep the CMs happy while you’re operating your own line?

We can do this by continuing to give them work. They are currently happy with us routing jobs through them, and I expect this to continue. It means they don't have to go searching for customers.

Last autumn we sourced boards (both fab and assembly) in the US. The vendors I’d used in the past in MV and Sunnyvale are gone but some folks are still around. Getting the boards made was slow for the reasons you said but the real problem was the parts: by mid summer 2025 the supply chains had become so disrupted that getting parts from mouser and digi-key was difficult. Design in a part with 6000 in inventory only to find by the time you ordered there were none because someone had scooped them all, unclear when they’d be replenished. Managing, connectors that didn’t match the datasheet. Etc.

Never again. Chinese shops are faster than US manufacturing. And they take Digikey and mouser part numbers.

It's also the immense know-how Chinese manufacturers have accumulated at this point. For a 5-piece hobby order $25 shipped, I got feedback confirming a wrong-looking part of my design before they printed.

Which manufacturer was that?

JLCPCB.

Disclaimer: CTO & Co-Founder of AISLER here We're trying to make electronic manufacturing (PCB & PCBA) simple, affordable and speedy. A high grade of automation allows prices starting at 12.20 Euros including VAT and shipping. Our software platform is completely built in-house, including state-of-the-art ODB++ integration. Let me know if you've any questions, happy to answer.

Thanks for being open to questions. I always wanted to know this: 3 copies of a simple 50x50mm, 6 layer, board is 184€ and takes 13 days to make as per https://aisler.net/en/products/boards - for comparison, JLC makes five 100x100mm 6-layer PCBs in 11 days, for $2. (And no, it's not only because of the (always available) coupon. Pricing generally gets better at higher quantities.) So my question is: why is 6 layers s…

Happy to answer that question! In the end it's a numbers game. Manufacturing gets cheaper with higher demand. For 6 layers the demand is rather low. We've figures from a US PCB comparison site and the share of 6 layers and more is below 5%, everything else is 2 and 4 layers. JLC serves a huge domestic market, so even with niche products they can do order pooling. That's not possible for us, thus the difference between 4 layers (€28.29) and 6 layers (€184.83). If there would be more demand in general, we could offer much lower prices.

Thank you. I hadn't expected it to just be lack of demand/scale. All the best with Aisler; I really hope the EU's renewed interest in local production will lead to more business for you.

Low utilisation would be a good thing as they would value availability to the line very highly.

Yes and no, I could imagine a system where they have on demand capacity with a company like us and pay for that service.

I see what you did there. :-) Good luck with your venture btw.

And their ability to pollute without regard for life or the future.

I ran a hardware startup for about a decade. We ended up doing all PCB assembly in China. We did try to find this in the USA, but it was indeed too slow and expensive. The bottleneck in assembling a PCB is usually component sourcing. My product was not the most complicated, and even then, to assemble in Shenzhen, China, it often took a few weeks to get all the components. The core issue here is that latency is determ…

Well, you’re asking for a design that boils down to a single channel downconverting I/Q ADC for 21.4 MHz IF, how many such products do you think there are? The ones by TI have been discontinued, your FPGA has no budget to do it and you don’t want one with more oumph so ADI it is … and Mouser says they have 800 on order, so that’s our only option.

But a chip for a 21.6 MHz IF may have 300000 in stock right now, you see the problem?

Love the energy, but I can hardly believe the title "Proven Metals" because your website does not stand up to basic scrutiny: 1) First issue: I do not know what your manufacturing constraints are for PCBs...the number of layers is not documented. I don't even know if you support FlexPCBs. 2) I suppose I could figure out if you could make my boards in seven days if I played your upload game...but I should have to do t…

1) Well noted, we are working on fixing that 2) Agreed, fixed with 1) 3) We should be more clear about testing. We offer a range of tests (in house x-ray, functional, bring-up) that we should show more clearly. 4) This will be made more clear on the site 5) We don't aim to be a broker in the end. We aim to own the whole stack. This is how we start. 6) True, we do in-house testing and rework, which should be more clea…

I looked at your site again and see you made changes. Stop working so fast, it's actually hurting your presentation pretty badly. I see "We make PCBs fast". I suppose it may mean something to the layman, but to me it just means you do what 4PCB does, except not in 24 hrs like they do. But never mind about determining turn time. When I click that I only see a single time listed (5 days). But if I look at the top of the screen I see another turn time of 7 days.

Just stop working on this site for 3-4 days and get your mission statement together. Maybe put some pictures of actual test fixtures if you test boards or any of your rework equipment. Every PCB/PCBA shop out there puts rework videos on its 'gram. It's just really hard to understand your business with this edgy/terse hustler kind of talk. Or your careers page where I get the sense that move fast and break things is the backend philosophy. Not a good look for someone who wants PCBs fast.

I so want this to work but holy cow I can't even understand where you guys are coming from.
