Etch a circuit board with kitchen supplies

I used a cheap* Chinese service recently and the quality was excellent. They're a great option if the dimensions of your design make OSH Park's by-the-square-inch pricing uneconomical. In addition, the boards were delivered in under a week.

*100mm x 150mm x 2 layer x 10pc order for $44

If you can squeeze your board down, 100 x 100mm seems to be the sweet spot with the cheap Chinese board makers that I've used [1].

10 boards under 100x100 are typically around $5-10, whereas a 10mm more pushes it to around $30

JLC are currently showing me some sort of promotional pricing of $2 for 10 x 100x100mm 2-layer boards (+$6 shipping - I'm close), which is ridiculously cheap.

I’ve done a ton of those boards with JLCPCB now. I think possibly 200 boards. It’s ridiculously cheap.

They’re the best of the lot as well.

I’ve tried others but they all seem to have layer registration problems or screw up the edges of your boards when panelising them (OSHpark do that)

Thanks for the links I didn't know about these services.

They use TG-130 or TG-140 which are lower temperature (130C/140C) FR4 board ratings. The surface may melt when de-soldering at high temperature. I usually prefer TG-170/TG-180 boards as I find them to be more reliable during rework.

But can't argue with those prices. :)
