1, must be operated with electrostaticring, the human body can produce more than 10000 volt static electricity, and300V or more IC will be damaged, so the human body static electricity needs todischarge through the ground wire.

2. When operating with gloves or fingersleeve, bare hands shall not directly touch the machine board and the parts ofgoldfinger.

3. Correct welding temperature, weldingAngle and welding sequence should be maintained and appropriate welding timeshould be maintained.

4. Take THE PCB correctly: Hold the edge ofthe PCB correctly when taking the PCB. Pcba processing SMT and DIP areintegrated parts on the PCB board. The main difference is that SMT does notneed to drill holes in the PCB, but the PIN pins of the parts need to beinserted into the drilled holes in the DIP. Do not touch the components on thecircuit board.

5. Use low temperature welding as far aspossible: high temperature welding will accelerate the oxidation of the ironhead and reduce the service life of the iron head. If the iron head temperatureexceeds 470℃. Its oxidation rate is twice that of 380℃.

6, do not apply too much pressure on thewelding: when welding, do not apply too much pressure, otherwise the iron headwill be damaged and deformed. Heat can be transferred as long as the iron headis in sufficient contact with the solder joint. Selecting different tipsaccording to the size of the solder joints also enables better heat transfer ofthe tips.

7. Do not tap or shake the nozzle duringwelding: Tapping or swinging the nozzle will damage the heating core andsplashing tin balls, shortening the service life of the heating core. If thetin balls splash on the PCBA, a short circuit may be formed, resulting in poorelectrical performance.
