Excessive solder, general

more examples

Solder accumulated at a wettable test point on the PCB. The solder accumulation has to be removed by suitable means because it impairs the subsequent electrical test.

  • poor parameter of the wave soldering process (soldering angle, temperature)
  • contamination of the solder / alloy
  • unsuitable flux / poor flux application
