Even if the design is somewhat novel, I'll use oshpark for the prototypes. Only thing with oshpark, I really wish they would just offer green boards, getting tired of looking at purple. For bigger jobs AdvancedPCB does good work with decent pricing and turn around.

Where are the top American PCB manufacturers and why am I not seeing more of them advertise the way JLCPCB and PCBWAY do? @advancedpcb @SanminaCorp @TTMTech

Rebuilding PCB manufacturing in the U.S. requires a strategic focus on high-tech niches like HDI, flex, and 5G boards, rather than competing with China's mass-market dominance. Key steps include acquiring and scaling companies like AdvancedPCB, MacroFab, and Qual-Pro, investing in automation and skilled labor, and securing government support through incentives and R&D funding. By leveraging domestic strengths in technology and security, the U.S. can carve out a profitable and secure niche in the PCB market. x.com/SkylineReport/status/1…

🚨Rebuilding U.S. PCB power means specializing in high-tech niches, not chasing China’s mass market. Buy & scale AdvancedPCB, MacroFab, Qual-Pro. Invest in automation, secure supply chains, and gov’t support. Focus on profit & security! 💡💥 #PCBReshoring #TechRevival

Interesting thread but I strongly disagree here. I have been in automotive industry on the manufacturer side and on the vendor side and in both cases I absolutely can't stand the old school approach to customer service. When I became engineering manager at the machine builder I used to work at, we saved SO MUCH money by ditching the old school sort of "patronage" system where we bought from our little circle of small vendors that we had personal relationships with... Sure, they might buy us lunch once in a while, and they'd provide support on-site if needed or whatever, but they absolutely could not compete with Wi Automation or even freaking AMAZON. Even for custom stuff like you are talking about here... I once worked with a local "customer servicey" type place for printed circuit boards... Got the sales managers cell, he always answers and is super nice, etc. but when the rubber meets the road its lots of money and lots of excuses... Went online to a big player (Advanced Circuits, now called AdvancedPCB), submitted drawings using the automated web tool, answered a couple automated questions about what I wanted, ordered with a credit card at 3:30pm and had 10pcs for prototyping IN HAND the next day before lunch. Cost was more than 50% less than the other guy, I never spoke to an actual human, parts were perfect, and they even threw in a free t shirt and a bag of microwavable popcorn (odd I know, but I appreciated the snack 😂). I have had similar experiences so much that terms like "customer service" "small business" and even "local" have become huge red flags for me... I feel like places use this talk as a crutch to try to shield themselves from competition with bigger, more efficient players. Now whenever I can I go straight to the biggest, most soulless, impersonal giant business I can... Jeff Bezos may not stop by my facility and shmooze but guess what? I order from Amazon I get my shit dirt cheap and it's there on time every time without fail.

Industry leader, Peter Austin, CEO of @AdvancedPCB, makes a compelling case for American made #PCBs and the #PCBSAct in his @ManufacturingDive op-ed.
