In the semiconductor industry, even tiny particles can ruin chips and wafers. Cleanroom coverall jumpsuits protect wafers and equipment from dust, fi bres, and static electricity. To keep them working well, it’s important to take care of them properly, especially in Class 10 to Class 100,000 cleanrooms.
1. Wash Carefully
Cleanroom jumpsuits must be washed in special cleanroom laundry systems. Follow these tips:
• Use ultra-pure or deionized (DI) water.
• Avoid bleach, fabric softeners, or harsh detergents.
• Make sure the laundry area is clean so no new particles stick to the jumpsuits.
Proper washing keeps the jumpsuits clean and safe for semiconductor work.
2. Dry Properly
Drying is also important to keep the jumpsuits in good shape:
• Dry with HEPA-fi ltered clean air to avoid dust.
• Use low temperatures to protect the fabric and any static protection.
• Don’t overheat or leave in the sun.
This keeps the jumpsuit strong and particle-free.
3. Check Before Each Use
Always inspect the jumpsuit before entering the cleanroom:
• Look for holes, tears, or worn fabric.
• Check zippers, snaps, and seams.
• Make sure any static protection threads (ESD) are not damaged.
Even small defects can cause contamination in semiconductor cleanrooms.
4. Wear the Jumpsuit Correctly
Proper gowning is very important:
• Touch only the inside of the jumpsuit.
• Make sure it doesn’t touch the fl oor or dirty surfaces.
• Zip it up completely.
• Put it on slowly and carefully to avoid shedding particles.
Following the right steps protects wafers and keeps the cleanroom safe.
5. Store Carefully
When not in use, store jumpsuits in a clean area:
• Use sealed bags or clean cabinets.
• Hang the jumpsuit to avoid folds.
• Keep away from sunlight and chemicals.
Good storage keeps them ready for the next use.
6. Track Usage
Reusable jumpsuits last around 50–100 washes depending on the fabric and cleanroom class. Keep track of how many times each jumpsuit has been used to know when it should be replaced. This helps make sure jumpsuits always work properly and meet cleanroom standards.
