PCB Board Soldering Process 2
Despite the benefits, single-nozzle drag soldering has longer soldering times and lower efficiency compared to traditional wave soldering, but advancements in multiple nozzle designs are improving output. Special solder nozzles are needed for different PCBs, presenting a challenge for design engineers to ensure stable soldering. Preheating in the selective soldering process is essential for proper flux viscosity and can be customized based on specific needs.
