The Hot Bar Reflow Soldering process
Hot Bar Reflow Soldering is the ideal process for components that require very precise positioning. Pulsed-heated soldering differs from traditional soldering because the reflow of solder is accomplished using a heating element called a thermode (or Hot Bar), which is heated and cooled down for each connection. Pressure is applied during the entire cycle including heating, reflow, and cooling. Since pressure is applied during the complete cycle, the process is highly suited to parts that may disconnect during cooling down. Using the Hot Bar Reflow Soldering process allows multiple connections (up to > 100 mm length) to be made simultaneously in a single process cycle. Making these connections simultaneously also prevents wires from disconnecting while soldering the neighbouring wire.
