How to choose the soldering temperature when lead-free soldering
For the choice of lead-free soldering temperature, the thickness of the PCB, the size of the pad, the device and the surrounding area should have a large heat dissipation area. The recommended solder joint temperature is about 350 °C, and the soldering iron can meet the requirements. The size of the head is as large as possible, because the larger the tip, the larger the heat capacity, the lower the set temperature, and the less heat loss. In this case, the welding speed will be relatively increased to ensure the welding quality. The life of the tip is also greatly extended.
