During production the temperatures on the last 3 zones are approx. 20F higher than the setpoint. The other zones are operating within spec. We checked power, I/O, SSR's, thermocouples, and exhaust, but the issue remains. We did not check resista

ah ... but we had insufficient heel fillets in the old design toom when we had more pad area ... just not as bad

The pads are 0.070 x 0.012 ... as spec'ed, and as measured. The pad extends approximately 0.017 behind where the Class 3 fillet is required to be. (It used to be 0.037 on an older design that exhibited similar, but not as bad of heel fillets.)

Has anyone had any success in finding open circuits (i.e. ball present but not soldered to PCB) under collapsible BGA's using an Agilent HP5DX x-ray tester and the BGA2 algorithm? Can anyone recommend an elongated pad design which produces the neces

The assumption that a HASL Sn63 PCB can be soldered with SAC solder paste is likely a bad one. The board itself is likely FR4 which can be damaged by lead free temperatures. The HASL finish isn't an issue from the perspective of it's makeup and actu
