PIC1

PIC1 shows all connections uniformly circular & equal in area - good indication of complete/proper reflow.
PIC2

PIC2 Shows result of errors in component placement.
PIC3

PIC3 shows BGA bridge.
PIC4

PIC4 shows insufficient reflow.
PIC5

PIC5 shows missing balls.
PIC6

PIC6 shows cold soldering.
PIC7

PIC7 shows solder voids, we should control void up to 25% according to IPC Class 2.
