I’ll bet that’s with lead HASL and green soldermask. I want to go lead-free for environmental reasons, and for esthetic reasons I want ENIG finish and another color of soldermask, usually blue. (My product is a butterfly, and butterflies aren’t usually green.)
Yes, I will try to get some photos, although I don’t have a macro lens for my DSLR, and I don’t have a way to attach a camera to my microscope.
Yeah, I’m buying in small-ish batches because I’m not sure how much demand there is for my product, and I don’t want to be stuck with a bunch of boards I won’t use. Also, I’ve been tweaking my design a little bit each time.
Yes, I think I’ll just experiment with different fabs and see. I’ve been using JLCPCB so far, but I think I might try Elecrow next, unless anyone here has a better suggestion to try. (The only minor annoying thing is that I’m selling on Etsy, and Etsy requires you to list your “manufacturing partners”, so I have to update that when I change manufacturers, though that’s not hard to do.)
I haven’t really been paying attention to whether there are scratches on the “non-art” side. Yes, JLCPCB puts numbers on the front of the board, so I already flipped the board so that the front is really the back and vice-versa.
