The Double-sided circuit board assembly have copper tracking and component pads on the top and bottom side of the PCB board, and often each side is interlinked by through-hole vias. Double-sided assembly requires the placement of components on both sides of the PCB .
To populate the underside with surface mount components, the PCB is inverted and the pasting and component placement process simply repeated. The second pass through the reflow oven does not melt the previously soldered side, as the joints are protected from the direct heat by being on the underside of the assembly.
