Embossed Tape is treated for electrostatic-resistance to prevent electrostatic charges that might occur when the cover tape is peeled-off for mounting.
This enables reduction of pick-up problems for the mounting machines, as well as preventing ESD destruction of the semiconductors.

Since Embossed Tape faces less variation in pocket size caused by the environment (temperature, humidity), clearance in a pocket is stable.
This gives higher durability of the Embossed Tape when kept in storage under high temperature/high humidity, and contributes to a reduction of pick-up problems when mounting.
Pocket size variations were measured after leaving for one day under high temperature/high humidity condition (70°C/85%).
