Abstract
The transverse member (29) of a reflow soldering heater bar (23) is slotted at intervals to reduce thermal expansion. The slots (63), which typically extend orthogonally through the transverse member (29) and the connecting legs (61) of the heater bar (23), may extend diagonally therethrough to prevent missed welds.
