1. PCB must be processed before reflow soldering machine, to ensure that the components and board pads are in a solderable (clean and free of dirt, pads without oxidation, etc.) state.
2. Processing and welding must wear anti-static cap.
3. Processing welding wear anti-static gloves to avoid electrocution accidents.
4. If the soldering iron to use every day, should use the power socket switch to control the soldering iron on and off, or in the soldering iron power cord installed on the power switch to avoid frequent plugging and unplugging lead to loose, poor contact
5. Soldering iron head should not be immersed in solder for a long time, can not use other very corrosive chemical industrial products for solder
6. Small power soldering iron sometimes the heat does not reach, the welding time is too long, easy to burn electronic components, you can choose a slightly larger power soldering iron, sufficient heat, can reduce the welding time
7. IC in the entire welding should be the last to carry out, and must wear anti-static bracelets when welding, soldering iron to reliable grounding.
8. After the completion of welding, the residual flux on the circuit board should be wiped clean with alcohol to prevent the normal operation of the circuit.
9. After the completion of welding need to turn off the power, clean up the desktop.
10 soldering iron frequently used for a period of time, the need to replace the power cord to prevent the root of the power cord or internal breakage.
