Industry Applications

Desktop selective wave soldering machines of this type are well suited to industries that demand high reliability, including automotive electronics, industrial equipment, telecommunications, and medical devices — sectors where PCBs frequently combine surface-mount (SMD) and through-hole (THT) components. This technology is also widely applied across the automotive, medical, and military industries.

Advantages Over Traditional Wave Soldering

• Purpose-built for selective through-hole soldering on PCBs, allowing precise, targeted soldering at individual points without affecting nearby SMD components.
• Conventional wave soldering typically achieves around 75% solder penetration, while selective wave soldering machines can reach up to 100% penetration.
• Compared to full wave soldering, heat input into the board is significantly lower and no solder mask is required — ideal for boards with heat-sensitive components.
• Selective soldering is the preferred choice over traditional wave soldering for complex PCBs, mixed-technology boards, or when only specific areas of the board require soldering.

Compatible Components & Boards

Suitable for soldering connectors, relays, transformers, and other through-hole leaded components on high-density boards or boards combining SMD and THT technology.

Standards & Certifications (Industry Reference)

Selective wave soldering machines in this category commonly meet CE, ISO9001, ISO14001, and RoHS standards, ensuring stable performance and compliance with global requirements.

Nozzle Selection Notes

Key factors to consider when selecting a soldering nozzle include interchangeable nozzle sizes (typically 1–5 mm), laminar flow design to minimize solder splashing, and dual-wave nozzles for soldering adjacent pins simultaneously. The RF-BFH331 comes standard with a Precision Turbine Nozzle, which can be customized similarly to common 4-6-47H style nozzles available on the market.
