Selective Soldering is an advanced soldering process used in electronics manufacturing to solder specific components onto a printed circuit board (PCB) without affecting other areas. Unlike wave soldering, which applies solder to the entire PCB, selective soldering uses a focused soldering iron or a soldering nozzle to target only the joints that need soldering. This process is ideal for soldering through-hole components on PCBs with both surface-mount and through-hole parts. It provides precise control, minimizes the risk of damage to sensitive components, and is especially useful for low to medium-volume production runs or complex boards.
