INSUFFICIENT WETTING (PIN)
INSUFFICIENT WETTING(PIN)
This solder in this joint has not wetted the pin at all and has only partially wetted the pad. In this case, heat was not applied to the pin and the solder was not given adequate time to flow.
REPAIR:
this joint can be repaired by re-heating and applying more solder. Be sure that the tip of the hot iron is touching both the pin and the pad.
PREVENTION:
Even heating of both the pin and the pad will prevent this problem.
