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.
