Dicing Die Attach Film｜Tape for Semiconductor Process

Die Attach Film is adhesive film which is used for semiconductor process.

It is combined with dicing tape, and it is called as Dicing Die Attach Film.

Optimized dicing tape for Die Attach Film achieves excellent pick up performance
Applicable dicing process is not only blade and also stealth laser dicing
Conductive Die Attach Film is also available
