[0002] Soldering is a welding method that uses a low-melting-point metal solder to heat and melt, then penetrate and fill the gaps between metal parts. It is named because the solder is often a tin-based alloy. A soldering iron is often used as a heating tool. It is widely used in the electronics industry, especially in the circuit board manufacturing industry. Soldering is used to solder electronic components on circuit boards. When soldering electronic components, a circuit board soldering manufacturing device is used.

[0003] After exploration and analysis, the following shortcomings exist in actual use:
