I get a decent bit of these fire alarm panel boards. (second pic)Assume I remove all the capacitors and other junk, I'm guessing high grad perf.

Next (first pic) is some boards out of some old telecom equip. I'm torn if it would qualify as high grade tele.

Nothing fun on back sides of any of these boards pictured.

Thanks for your help, first time posting and getting ready to ship some boards out.

Yellow boards, high peripheral

Blue board, leaning mid grade but might clear low peripheral as is. Removing the capacitors and excess steel connectors would probably get you at or near high peripheral.
