Circuit board soldering generally involves reflow soldering, wave soldering, and electric iron soldering. Reflow and wave soldering are automated processes and are less susceptible to human error, while electric iron soldering is manual and more susceptible to human error.
1. Select the appropriate soldering temperature. Using a soldering iron at too high or too low a temperature can easily result in poor soldering.
2. Solder components from small to large. Solder smaller components first, then larger ones.
3. Pay attention to polarity reversal. Some components, such as capacitors, resistors, diodes, and transistors, have specific polarity; avoid reverse connection during soldering.
After undergoing SMT placement, DIP insertion, reflow soldering, wave soldering, or manual soldering, a PCB becomes a PCBA. Automated PCBA processing technology is becoming increasingly sophisticated. Manual soldering is often performed for several reasons: Electronic components are not resistant to high temperatures. Due to the implementation of EU RoHS and WEEE regulations, lead-free processes are becoming increasingly popular to accommodate and meet customer needs. During wave soldering, the furnace temperature is higher than that of lead-free processes, so some electronic components that are not resistant to high temperatures cannot be wave soldered.
Our 30,000-square-meter factory houses 24 SMT production lines, 8 plug-in lines, 4 wave soldering lines, 8 assembly lines, and 4 packaging lines. Equipped with a comprehensive digital management system, we are committed to building an Industry 4.0 smart factory. We offer comprehensive Industry 4.0 solutions, including PCBA (Printed Circuit Board Assembly) and SMT (Surface Mount Technology) fabrication services, as well as OEM and ODM services.
