Type AA® Cover Tape is an antistatic, transparent, heat sealable cover film. It is engineered to protect and contain surface mount components in embossed polystyrene carrier tapes.
Type AA® Cover Tape contains a top layer of 0.00092” thick polyester base film and a bottom layer of 0.00128” thick heat activated adhesive coating layer. Both layers are antistatic to ensure the protection of static sensitive devices.
Type AA® Heat Activated Cover Tape is provided standard with 300, 400, 500, 600 and 1000 splice-free meters on a 3” inner diameter plastic core. Widths available include all EIA standard widths for carrier tapes between 8mm and 56mm, plus custom widths by special request.
