Currently, there is a growing demand for environmental protection and stronger measures in link governance in the country. This poses a challenge as well as an opportunity for PCB factories. By actively addressing the issue of environmental pollution, PCB factories can position themselves at the forefront of the market with FPC flexible circuit board products and regain the opportunity to grow.

1. To prevent damage to ICs, it's important to discharge static electricity from the human body through a ground wire when operating with an electrostatic ring. The human body can generate static electricity above 10,000 volts, and ICs above 300V can be damaged.

2. When wearing gloves or finger sleeves, avoid touching the machine board and golden finger parts with bare hands.

3. For proper welding, ensure that the temperature, welding angle, welding sequence, and welding time are correct.

4. Take PCB correctly by holding the edge of the board. Both SMT and DIP processing by PCBA integrate parts on the PCB. The main difference is that SMT doesn't require drilling holes in the PCB, while DIP requires inserting the PIN pins of the parts into the pre-drilled holes. Avoid touching the components on the circuit board.

5. Use low-temperature welding whenever possible. High-temperature welding can accelerate the oxidation of the iron tip and reduce its service life. If the iron tip temperature exceeds 470 degrees Celsius, the oxidation rate is twice that of 380°C.

6. Apply appropriate pressure when welding to avoid damaging or deforming the iron head. As long as the iron tip can fully contact the solder joints, heat can be transferred. Choose different iron heads based on the size of the solder joints to ensure better heat transfer.

7. Avoid knocking or shaking the iron nozzle during soldering as this can damage the heating iron core and cause tin beads to splash, shortening the heating iron core's service life. If tin beads splash on the PCBA, a short circuit may occur, leading to poor electrical performance.
