Selective Soldering

Selective soldering uses a precise nozzle to apply solder only to designated areas of a PCB. This process is especially useful for mixed-technology boards with both through-hole and surface-mount components. Stewart Technology operates three selective soldering machines, allowing precise control over each solder joint. This makes it possible to solder components in areas that cannot be wave soldered and manage complex or delicate board designs. Selective soldering reduces thermal stress on sensitive components and prevents solder bridging, improving overall board reliability. This high level of control ensures that even the most complex assemblies are soldered accurately, which is critical for boards with tight spacing or sensitive electronic parts. This process provides a balance of efficiency and precision, making it ideal for customers who need reliable mixed-technology assemblies, while maintaining maximum product quality.
