Wave Solder Process

Wave soldering is a process where the PCB is passed over a pattern of standing waves of molten solder.  The wave solder machine carries the PCB on a conveyor through a flux spray applicator, a pre-heater, and then through the solder wave.  This machine ensures that sufficient flux is sprayed onto the PCB and that the PCB is then gradually heated to a specific temperature to allow the solder to flow through the component lead holes and provide correct fillets.  Wave soldering is applicable to most PCBs and provides for a fast consistent solder process.
