Usage Precautions

  1. Storage Conditions: Keep in a cool, dry place (15‑30℃, 40‑70% RH), away from direct sunlight, high temperature, and high humidity.
  2. Moisture Protection: After opening, it is recommended to use the entire reel at once. If not fully used, reseal for moisture protection.
  3. Sealing Parameters: When using for the first time, adjust parameters according to carrier tape material and equipment characteristics.
  4. ESD Protection: Ensure equipment is properly grounded during use to prevent static buildup.
  5. Peel Force Verification: Use a peel force tester to verify that the peel force is within the specified range before production.
  6. Shelf Life: Use within 12 months of unopened original packaging. After expiry, re‑validate sealing performance.
