PCBA Soldering Techniques and Troubleshooting Soldering is the linchpin of the PCBA process, forging both electrical and mechanical bonds between components and PCBs. Several techniques, each with distinct merits, cater to different needs: Manual Soldering: Ideal for small - scale production and prototyping, this method relies on a quality soldering iron with temperature control. Clean the tip, tin it, heat the lead and pad together, then apply solder. Precision and avoiding overheating are crucial. Reflow Soldering: Tailored for surface - mount components, it involves applying solder paste, placing components, and passing the PCB through a reflow oven. The right temperature profile is key to success. Wave Soldering: Used in high - volume through - hole production, it passes the PCB over a molten solder wave. Proper pretreatment and optimized machine settings ensure good soldering. Selective Soldering: Perfect for boards with mixed components, a robotic head precisely solder
