Type AHPC Cover Tape is a clear, antistatic, heat sealable cover tape engineered to protect and confine surface mount components contained in our carrier tape. AHPC is designed to adhere at various temperatures and dwell times within industry standards.
Type AHPC Cover Tape is constructed in two layers, a 0.00092” polyester base film covered by a 0.00128” heat-activated adhesive coating layer. Both layers are antistatic to protect static sensitive devices.
Type AHPC Cover Tape is provided splice-free on 3” inner diameter plastic cores.
Recommended Sealing Conditions
The detailed sealing parameters apply to single strike seal mode. Multi-strike, or overlap sealing, may require adjustment outside of these ranges.
|Temperature||170° – 200° C|
|Dwell Time||0.2 – 0.5 sec|
|Pressure||30 – 35 PSI|
|Seal Rail Width||0.015 – 0.020″ (0.38 – 0.51 mm)|
Shelf Life and Storage
Type AHPC Heat Activated Antistatic Cover Tape has a shelf life of 24 months from the date of manufacture when kept in recommended conditions. Store this product in its original packaging in a climate-controlled environment where temperatures do not exceed 40°C (104°F) and relative humidity is under 80%.
