content: This tariff chaos is a disaster but I can't quit trying.Since the China/US tariff fight looks to be settling into a long haul, I have started actively looking for an alternate assembly house. I have heard about Vietnam as an alternative. Maybe Cambodia? I have several products that I make and sell. A typical one is a board (10 x 10 cm) that has around 140 smd parts (46 unique), mostly Rs and Cs (402 and up), some jellybean ICs and a small number of specific ICs/components (microcontroller, flash memory, VRs, crystal, inductor). No BGAs, one QFN80 part, min trace is .1 mm. 2 layer. Also, a number of TH connectors that I want to get sourced/assembled - 5 different types, 40 in total. I'd be willing to tweak my design to make it easier to build.So, I am looking for an assembly house that can handle this for 200-500 unit orders. My annual run rate could be 1000 or higher. I will have an example they can work from (as well as BOM/Pos/gerber files of course).I would appreciate any suggestions you might have. Especially for companies you have worked with on similar projects. I have looked at several past posts on this topic (one from Feb '25 has a good VN suggestion). I am especially interested in how easy it was to work with these companies. Can the project be done without traveling there? (though I like VN and wouldn't mind mixing it with a vacation.)Thanks in advance.

content: Many years ago (Pre-everything comes from China) a friend of mine had some products assembled somewhere down in the Caribbean at a very reasonable rate. At the time, their labor rates were a lot lower than in the US and they gave him some decent tax incentives.Also a long time ago, another friend of mine owned a small electronics assembly company in Baton Rouge.And I know that today there are still a good number of small electronics manufacturing companies around Titusville and Melbourne, Florida.

We're going to miss China!

content: Has anyone priced Digikey's DKRed?https://www.digikey.com/en/resources/dkredWondering how for basic 4 layer boards it compares to JLCPCB, for prototype quantities (they require 4 mininum).They do 0.2/0.41mm vias (8/16 mil) and 5/5 w/s but otherwise looks like a reasonable replacement. And I'm fine with those. ENIG seems standard.They claim it's all in the USA.Edit: 4x3" seems to come out to $72 for four 2 layer boards, twice that for 4 layer. They do include free shipping. Price is entirely tied to size, with seemingly no fixed sizes, so every mm in reduced dimensions reduce cost.Edit 2: priced a specific board, 100x70mm, 4 layer, 0.3/0.45 vias on both JLC (HASL) and DK (ENIG), and the total is about twice as much from DKRed, when adding DHL shipping from China to JLC. So it's actually cheaper from DK with the tariffs. I think I'll give them a shot next time...

content: Quote from: jayx on April 12, 2025, 09:10:55 pmGoing by Digikey/Mouser, component prices are anywhere from 30% higher to at least an order of magnitude. Connectors are the worst case. My boards pencil out to US based distis connector prices alone add up to triple the entire Chinese assembled per board cost, delivered. And, most of the US disti connectors have an import tariff note so they are already being imported, probably from China. Even at 150% tariff, China still pencils out cheaper. But I seriously do not know if I have business left at that point.

content: What about importing into Canada (or Mexico), doing some partial assembly work (if required), and then final import into US? this has been the playbook of auto MFGs for yearsOr ship from Canada to your customers?These aren't suggestions, but ideas for discussion. I've never done the above, don't know if its legal, if it would help reduce tarrifs, etc. But I am curious to hear from anyone who has experience with these approaches. What all was involved? is it hard to setup a CA entity, or are there brokers that can do this, etc.So long as the CA-US situation doesn't re-exploded, seems like dealing through a Canadian entity, direct to JLCPCB, would be easier than working through a Thailand/Vietnam/India firm dealing with JLCPCB.

Of course, they can fraudulently declare a different country, but this can be done already for shipments from China. It also would only work for a short time until the feds wisen up, and then that country will face a diplomatic pickle.

content: I would consider making the productin the US, and if necessary buying parts from China (I use LCSC) via another country.I used to build complete stuff in China, for about 20 years, but by ~2018 pulled it all back here. Loads of reasons e.g.- business climate there is dog eat dog / california gold rush- firms vanish every few years and you lose all tooling, continuity, etc- payment is 100% in advance (30 days credit domestically)- shipping time by sea is 1.5 months, plus loads of charges from the criminal gangs (shipping agents) at the ports, against 1-2 days domestically- etcAdd up all that crap and China comes out not so cheap. And prices are going up all the time.You can still buy PCBs and components from China even if they are now 2x the cost.I would not use any assembly shop here in the UK. Too much bad work. Probably doable for pricey products though; the assembly firms I know here are all doing 3 digit priced products. Getting PCBs populated here, from free issue parts, is enough funI use outworkers for product assembly, with sample testing back here of the finished items. The US, like every country, has loads of "poor people" who ought to like to work at homeMr T will be gone in less than 4 years, possibly sooner due to old age. Then things will cool down.I looked at S Korea (I don't like giving business to a military enemy) and it is pretty hard even for bare PCBs. 2x the price of China and poorer/harder comms than even China.

Yes, in fact if our experience means anything a very large part of our business comes via word of mouth and recommendation.There are assemblers in the UK working at almost every scale, of course margin is easier to find in a more expensive product or a full assembly but that doesn't mean we don't do the simple and cheap stuff too if required.Solo engineers who think they know everything while having practially zero manufacturing experience, now there's a problem this industry is riddled with.

I don't know where the actual manufacture took place.For example,Nexperia 74HCT595D,118 Mouser - Q100 $0.321, Reel (2500) $0.225; LCSC - Q150 $0.1516, Reel(2500) $0.1159TI TPS54202 Mouser - Q100 $0.553, Reel (3000) $0.439; LCSC - Q150 $0.1562, Reel (500) $0.1382I could go on. Some western parts (usually single sourced) are very close in price. Maxim, for example. And some, PR2350 for example, are slightly higher.Chinese versions of standard chips (BJT, MOSFETS, 74 logic) are significantly cheaper. Resistors and caps are ludicrously cheaper.Connectors are way cheaper but hard to make a fully apples to apples comparison.The component BOM cost of a recent product I made was a factor of 1.5 if you exclude connectors. >3X if connectors are included. And the bare PCB cost is ridiculous.

content: I found the same, USA prices through DK/Mouser are 25-50% higher than JLCPCB/LCSC on the EXACT same part even at $500+ quantities. Volume wise, I assume the US market is a fraction of the Asia market for electronic components.FWIW some MFGs, TI for one, are often lower priced than DK/Mouser, and sometimes even less than LCSC. But not on every component.

content: We have already received orders that would have normally gone to China simply because of the tariff uncertainty. We are a US based assembly house. If you'd like, you can go to our website, click Get A Quote, then in the Additional Information section mention EEVBlog and I will do a DFM review for you during the quoting process and include opportunities I find to reduce pricing.Manufacturing in the U.S. civilian market exists largely due to continuous innovation aimed at reducing labor costs. While it’s often framed as a simple challenge, labor costs impact every aspect of a business—inventory management, real estate, storage, compliance, taxes, and supply chain logistics—all of which are significantly more expensive in the U.S. compared to overseas markets.For context, companies like JLCPCB stock millions of unique electronic components—many of which are sourced and manufactured locally in China, reducing both costs and lead times for them. Their 24/7 production model and infrastructure are built around high-volume, low-margin efficiency, making it nearly impossible for small and medium-sized businesses in the U.S. to operate under similar conditions without massive capital investment and risk.That said, there are benefits to U.S. based assembly (especially if you're located in the U.S.)1) Lead Times – When ordering PCB fabrication and assembly together, the longest lead time typically comes from bare PCB manufacturing, not component selection. Choosing stocked components does not usually reduce build time.2) Pricing – We negotiate volume pricing with all major suppliers and pass those savings on to our customers, ensuring competitive pricing even without a massive pre-stocked inventory.3) Flexibility & Support – Unlike overseas manufacturers, we work closely with our customers to refine their BOM and assembly process, ensuring optimized performance and cost-effective alternatives.4) Quality - You should see a noticeable improvement and when issues do arise, we don't slap a credit on your account, we fix it.The bigger problem is, I believe, that you are still going to get hit with tariffs for components that are sourced from China. Moving Country of Origin for components using globally sourced raw materials is not as simple as shopping a new labor source and will require heavy investment in equipment, talent, and a readjustment in the supply chain. Those things will take years.We offer turnkey options for our customers and as the tariff bar keeps shifting it has been, to put it mildly, a real challenge to manage.

Either Belgium or Netherlands, but also in Central or East Europe occasionally. It all depends on the size of the company you are looking for, and the production quantities. There is no one size fits all.Europe is overall very price competitive with China, if you pay the same amount for the components. I was looking at the total cost breakdown of a product of mine, and the total subcontracting costs for the PCBA was 7%, and additional 7% to go from PCBAs to final product (in house). And that's for something assembled here.You can outsource it and then maybe save 4-5% of the final cost price? And deal with quality issues, shipping uncertainties and so on? And it's not like the EU doesn't have tariffs for Chinese parts.

I suggest you concentrate on what you are good at and let Jack do what he's good at. I have received 50 to 100 deliveries from him batches of 50 to 1000 panels. Both SMD and through hole components run through the line, from auto stencil to auto stacker at the end.I have added a couple of images below. Sorry for my poor phone camera & all the black boxes removing identifiers, lawyersAs you can see from the panel I had lying around near my desk, they are happy to run several different builds on a PCB, populating only the required parts per build.
