1. The operator must wear a grounded anti-static wrist, wear anti-static shoes and anti-static clothing.
2. If the LED is damaged by static electricity, it will show some bad characteristics: the leakage current increases, the static forward voltage decreases or rises, and it does not light or the illumination is abnormal under the low current test.
3. All equipment and instruments that are in contact with LEDs must be well grounded. Specially soldered soldering irons and tin furnaces must be well grounded.
4. The anti-static wrist must be tested every day. If it fails, it must be replaced.
