Cover tape for carrying thermo forming electron with superior applicability.
Cover tape classification:
Heat-seal type
Pressure sensitive type
Application
Electric parts and semiconductor carrying
Product Features
Stable surface strength , easy to be set bending conditions.
Favorable usability for variety carrier tape materials (PS，PC，PET，PVC)
AT,ATA specifications: high transparency ,strong visibility,outstanding cost performance
ATA specification: More suitable for anti-static packaging for small parts due to the slight frictional electrification of epoxy packaging.
