In PCB production, a plated through-hole can pass the finished-hole diameter check and still cause concern at final inspection. Under magnification, the hole may sit close to one edge of its pad, leaving almost no copper on that side. A correct diameter tells us the hole is the right size. It does...
A dark gap in a plated through-hole cross-section needs a location before it needs a diagnosis. Is copper missing on the barrel wall, at an inner-layer connection or near the hole entrance? The answer changes which process records the fabricator should review. PCB plating voids are local areas whe...
A drilled hole can look clean at its entrance while resin still covers an inner-layer copper edge inside the barrel. That thin film matters because the later copper deposit needs to meet exposed copper, not a layer of insulating resin. The PCB desmear process addresses that interface after drillin...
