I was expecting it to be yellow… Not sure what I have done wrong.

That’s really weird, shouldn’t the front panel be the same colour as the pcb?

The PCB color is yellow solder mask on top of copper, the panel looks like bare FR4 (no fill, no mask, just the silk screen).

(or maybe it is mask on top of raw FR4?)

EDIT: Yeah, I suspect it’s yellow mask on raw FR4; white/black tends to be more opaque, and the yellow one is extra bad.

(Also, some random googling brought up https://docs.oshpark.com/services/afterdark/ which looks like an interesting option for stylish front panels.)

Huh. I thought I specified a copper layer under the mask on the front as well as the back. But looking again at the KiCad file, it’s only on the back. An omission on my part. Not that it’s needed electrically or anything, and it looks okay with the white solder mask. Anyway, just in case it ever matters, I’ll put it in. Sorry about that.

Yeah the OSH Park After Dark sounds interesting, if you’ve got the pockets for it.

No worries, good of you to share your work in the first place., was not sure if I had just done something wrong.

Hopefully my own PCB may turn up tomorrow…

Just checking… how’s the back of the panel look? There should be a copper layer there (@ChristianBloch soldered to it!) so I’d expect it to be more the expected color.

Yes, it does look correct on the back.

That OSHPark place is SUPER expensive for KOSMO sized boards…
Not even their Afterdark service - 3 Braids Conversion Panels would be 132 bucks. lol

Got some boards here


and some aluminum

That came from midweststeelsupply.com, which had the lowest prices of any of the US places online or local I investigated… in the case of the 10 by 20 cm panels, literally about a factor of 7 smaller than what couple of other places were charging. (For five pieces. There are only four in the picture for some reason but I did get five. They were all much closer in price for single quantities, but a couple of them didn’t give you any discount for more than one.) Altogether including shipping this cost me about $47. I could only specify to the nearest 1/8" and they quoted tolerances of -0 +1/8". For the 10 cm dimension which is close to 3 15/16" I ordered 3 7/8" figuring I’d rather they were a little narrow than a lot wide. Everything seems to be within about 1/16" of the dimension I ordered, or just slightly over that; I measured one of the small pieces at 99 by 200 mm. I don’t know if the scratching you see is worse than what you should normally expect or not but for now I think I’m okay with the quality here.

well something finally showed up . stuff from the surplus place , not really anything needed to finish the projects . well maybe the fuse blocks for my power supply’s will help me finish those up . the funny thing is this was the most recent thing I ordered .
