Question:

In order to solve the problem of static electricity damage, an enterprise has carried out anti-static modification to the production line. Although the defective rate of SSD products has decreased after the modification, the percentage is still high.

Solution:

1. After on-site analysis and investigation, it was found that most of the test fixtures and operating tools on the operating line were made of insulating materials.

2. The presence of some isolated ground-insulated metalwork at the operating site.

3. When operated by personnel, the friction between objects and electrostatic induction often electrify the above supplies, causing adverse effects on SSD products.

4. Enterprise production line to promote the use of ion electrostatic eliminator. After another comparison test, the defective product rate than before the use of ion electrostatic eliminator decreased by about 6%.
