1. During welding, the colloid shall not be immersed in tin.
2. When welding and heating, it is not allowed to apply force to the lead wire, it is not allowed to move, and it should be fixed.
3. General welding conditions: (at the position where the pin length is more than 3mm) manual welding: 300 ℃ < 2 seconds 260 ℃ < 5 seconds wave soldering: 260 ℃ < 5 seconds
4. If there is forming requirement, it must be carried out before welding, at the position more than 5mm away from the colloid.
5. Since the device is a sensitive device, electrostatic protection, equipment, desktop, electrostatic ring and other grounding are required.
6. When forming, pay attention to fixing two pins to avoid strain, and use fixing fixture.
