Specific measures to avoid static electricity in the purification workshop
Specific measures to avoid static electricity in the purification workshop
1. Maintain the corresponding environmental humidity in the purification workshop. In North China or in dry winter, the common faults caused by electrostatic induction are far more than in coastal cities or other seasons. Therefore, in some key sites, such as computer rooms, semiconductor material workshops, and instrumentation production workshops, the issue of maintaining the corresponding environmental humidity should be considered. Especially for these closed air-conditioned workshops, there should be machines and equipment to manipulate the environmental humidity.
2. Semiconductor components should be placed in anti-static plastic containers or anti-static packaging bags. Such anti-static containers have good electrical conductivity and can reasonably avoid the generation of static electricity. Therefore, those that meet the standard should be contained in metal material containers or packaged with metal material foils.
3. The ion air gun, positive ion head, ion air rod and other equipment should be used in the purification workshop to avoid electrostatic induction in the corresponding range.
4. Install electrostatic floor or blanket. Existing plastic floor or blanket products with corresponding electrical conductivity can reasonably prevent electrostatic induction caused by people's walking.
5. The actual operating staff of the purification workshop should wear anti-static hand straps on their wrists. Such hand straps should have good grounding device characteristics. Such measures are more reasonable.

In clean area management and quality control, laminar flow interference testing has received much attention, and whether it is only applicable to Class A laminar flow remains to be considered.
