Selective Soldering - What is it?
Selective Soldering is the process by which conventional leaded components are soldered onto a PCB. Originally devised for soldering those hard to get to areas of a circuit board /assemblies which historically were carried out by hand operators using soldering irons. It has now become a recognised design process within the PCB manufacturing industry. This procedure is usually conducted after the surface mount reflow operation.
This form of soldering offers a significantly lower cost approach, over conventional wave soldering, when soldering through-hole components on mixed technology PCBs. It offers the ability to eliminate the need for costly wave solder pallets when using the traditional masking method. Furthermore, the quick interchange of solder baths e.g. eutectic to lead-free and vice versa, helps reduce production costs. Removing the need for hand soldering, can greatly assist product quality and result in an enhanced production throughput.

Selective Soldering - Inert Environments
By soldering in an environment with minimal oxygen level results in reduced oxidation and gives a number of benefits:
Pillarhouse International is the leading force in the Selective Soldering industry, dedicated to the ongoing development of pioneering technologies. Their Selective Soldering machines use an inert Nitrogen atmosphere in which to solder. This enhances the process performance of fluxes that would otherwise be ineffective because of their reduced content of fluxing agents. Pillarhouse soldering machines use a number of technologies to suit the specific customers’ needs. Whether that is the high precision and flexibility of the patented 1.5mm Micro-Nozzle; our all-purpose AP-1 nozzles; or the high speed options of the Jetwave/Multi-dip soldering method.
