The drag welding process offers precise, efficient soldering for PCBs in tight spaces, enhancing stability and reliability through controlled nitrogen supply, despite longer welding times compared to traditional methods.
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.
Selective soldering can be done using two processes: drag soldering and dip soldering, with drag soldering being ideal for tight spaces on PCBs due to its precision and heat efficiency.
