Thermode reflow soldering is a manufacturing technique for soldering multiple connections in one step utilizing a resistively heated thermode blade to reflow the solder at the connections. Soldering multiple I/O runners such as those used for LCD interconnects is a typical application for this tech- nology. There are several types of thermode blade types available. These are generally differentiated by the direction of heating current flow relative to the runners being soldered. Heating current in bar type thermode tips flows perpendicular to the direction of the runners. Fold-up type thermode blades pass the heating current parallel to the runners. Previous state of the art in fold up blades required a multi- piece design consisting of two support pieces with the heating section consisting offormed sheet metal section brazed between them.
