Back Grinding Tape

Main Features
- Strong adhesion to prevent water damage
- No adhesive residue keeps adherends clean
- Especially flat to help with grinding
- Can be used with uneven surfaces (bump wafers)
Other properties
- Reduced warping for ultra-thin grinding
- Heat resistance during grinding/polishing
- Can protect films for long periods and from heat
- Antistatic properties when peeling
- Chemical, acid and base resistance
- Protective function for high bumps

We offer two main types of tape: UV tapes which can be peeled without stress under UV radiation, and non-UV tapes designed to be peeled without UV radiation.
We can also change specifications and design new tapes especially for our customers upon request.
We also support trial production runs for small quantities. Please contact us to learn more.

Dicing Tape

Main Features
- High level of uniform expansion
- Reduces chipping
- Strong adhesive properties
- Prevents whiskers
- High heat resistance
Other properties
- Antistatic properties
- High transparency
- High elasticity

We offer UV-type dicing tapes that can be easily peeled off by reducing the adhesive strength through UV irradiation while increasing pick-up properties during die bonding.
We can also change specifications and design new tapes especially for our customers upon request.
We also support trial production runs for small quantities. Please contact us to learn more.
