Selective Soldering offers a significantly lower cost approach, over conventional wave soldering, when soldering through-hole components on mixed technology PCBs. By automating the soldering process you will not only improve product quality but this will also result in enhanced production throughput.
Solder Connection Puralloy® incorporates a range of larger diameter feed wires which have been designed with selective soldering in mind. The solder wire is manufactured to high tolerances and wound onto 4 kg reels at a constant tension to ensure a smooth take off through the machine feed mechanism into the solder pot.
