ü Visual inspection of the solder nozzle wetting
a) The solder nozzles must be completely wetted with solder (1) with an activated
solder wave.
b) Enable incompletely wetted solder nozzles(2).
c) Have strongly oxidized solder nozzles replaced by qualified staff only.
ð The process has now been completed.
