During machine soldering all parts to be soldered must come in contact with molten solder for a sufficient time to make reliable joints. However, also the parts in-between the joints to be soldered are in most common solder processes in contact with the molten solder during the soldering operation. In that phase of the solder process solderbridging is a normal part of the process. It is during separation between the solder source and the soldered joints, that we want to get rid of this unwanted solder bridging.
Next we will explain why solder bridges may, or will be present on a soldered PCB, and what can be done to avoid them.
