Good morning Mark, No issues around the masking at this point. The issue seem to be in open areas as well as between clad runs. We are using Humiseal 1A33 Conformal Coat.

My first guess is that the plating in the barrel (via) has failed and allowed laminate/epoxy egress into the barrel and out to the surface of the board. Just a guess based on the picture.... 'hege

PCB Supplier made an EDX anaysis, the found a chemical trapped in the holes, and some burnt burrs, according to what they say this stains are over the solder mask & silk, so they do not affect functionality.

It was fun and easy to be a Chiefs fan 1991 to > 1993. Not so much nowadays. Yes it was. This was the time of Joe Montana's last hurrah. An exciting time to be a Chief's fan.

Just an FYI regarding the 8080 buffers: When you replace the lithium battery in the display module, replace the one in the PLC as well. Of course, you will need the machine turned on when replacing the batteries.

I will treat it as any other BGA. Drill a hole in the board, put thermocouple and do your profile.

Unless you use the method Evtimov described, you will be guessing. And yes metal topped BGA's take heat differently than PBGA's
