Wave Soldering
Wave soldering is a mechanical and technique that allows multiple lead wires to
be soldered to a Printed Circuit Board (PCB) as it passes over a wave of molten
solder. In this process a PCB on which electronic components have been placed
with their lead wires extending through the through the holes in the board, is
loaded onto a conveyor for transport through the wave soldering equipment. The
conveyor supports the PCB on its sides, so its underside is exposed to the
processing steps, which consists of the following :
(a) flux is applied through foaming, spraying, brushing, and
(b) wave soldering is used pump liquid solder from a molten both on to
the bottom of board to make soldering connections between lead wire
and metal circuit on the board.
