Excessive solder at a SO

Description:
Rich solder joint at a L-lead. This solder joint is a borderline case for excessive solder. Since the solder does not touch the component body, the soldering result is still acceptable according to IEC 61191-2.It has to be made sure that wetting and solder fillet are immaculate.

Causes/Remedy:
  • poor process parameter for wave soldering(soldering angle, temperature)
  • contamination of the solder/alloy
  • poor flux / flux application
