It requires some conditioning but few days were enough to test wire frame #5. Now we are having problems with wire frame #6. We identified so far 8 caps that need to be replaced. After the meeting we continued with the tests and we found another 4, so 12 in total. Anatoly, who removed the caps, mentioned that on 5 of these there were solder balls below the caps somewhere between the pads (see pictures linked above). The balls are actually flat (like a coin). |
