@VoltageSpike Sunstone for bare fabs. Screaming Circuits, Tempo Automation, Sierra Circuits for assembly.

@Shalvenay usually under a baker's dozen

@NickAlexeev Thanks 👍

@VoltageSpike I've had good luck with Oshpark for small-scale stuff

Ditto, I <3 OSHpark.

I've worked with ferric chloride, perchlorate, and cupric chloride... sticker, pen, and laser-toner-transfer. Jumper wires and via plugs. All of those may work, to varying degrees... but even with decades of experience, none are nearly as good as a professionally-made OSHpark board. So all of those chemicals have been (safely and properly) neutralized. Stickers, discarded. Transfer paper, collecting dust. So much easier and nicer with a turnkey fab.

I've used Oshpark, I typically used pcbway but I've been hit by duty fees for bigger orders so I'm wondering if there is a comparable service. The nice thing is if it's a typical 4 layer board, I can pick and choose all the specs and pcbway just builds it.

Usually other services require a ~day just to get a quote
