Dear all, We have a PCB design mistake that causes exposed copper layers on the edges of breakaway locations. Although we fixed the design, but we already made a lot of boards plus many made before we found the problem. I wonder if any one have some

After the CCA is been de-paneled I find exposed board fibers. Should the board edge be sealed with an epoxy to keep moisture from getting into the CCA?

IPC-A-610F 10.2.6 Laminate Conditions - Depanelization talks to the acceptability of the depanelization criteria for assembled boards. There is no requirement for moisture sealing with epoxy or other material. Basically, the standard requires that th

Dennis, I've seen this before, and in our case we didn't need to seal the edges because there was no concern of shorting or anything in the end product, this is a choice you will have to make, Does your end product have any protrusions or mounting h

We are wave soldering some fabs with a lot of unmasked trace area along the edges. The trace area is solid copper covered with tin / lead, no masking, no components along the edges, same on solder side and component side (goofy board design). Inste

we are a PCB house, you can add some patterns at breaktabs or board edge, this can help you easily verify copper weight for every circuit layer.

Dave, Sorry for the slow response, have been out of town, The spacing I was referring to was from board edge to copper features. This spacing is required to keep the router and score blades from exposing or hitting the Copper. Regarding the slot I
