Application example

Removal of air bubbles in touch-cell lamination process

The OCA/LOCA lamination process in the TSP manufacturing can cause air bubbles to form between the window and the film/glass. Plasma treatment aims to remove/suppress the air bubble formations.

Enhancing ACF bonding strength

Surface treatment on the ACF bonding part of a touch cell using plasma enhances the bonding strength, thus improving reliability.

Pretreatment prior to anti-fingerprint coating on cover windows

Anti-fingerprint coating aims to prevent contaminations from the user’s fingerprints on the cover windows of smartphone and PADs.

Rework of anti-fingerprint coating

Anti-fingerprint coating process sometimes causes the problem of so-called back-coating effect, which means the backside of the coating surface gets contaminated with overflown coating liquid.
