If it has been determined that it is definitely the relays (and not some other circuit device), you'll want to get the vendor/manufacturer involved for some failure analysis. They'll cut open the components, and try to figure out what's going on in

Edri PCBA design and pad geometry is one of the critical factors for BGAs. Typically the pad size for collapsible balls is 80% of the ball diameter. Pad size consistency is critical. In your situation what will happen the larger pads will wick the s

gregp: Our PTH process has not changed in many years. Our products are fairly simple as far as electronics goes and everything gets potted anyways. ~90% of everything we build is single sided TH with ~ 100 solder joints per board. Each board is ~
