We offer various tapes.
Backside Coating Tape

The Adwill LC Tape was developed to protect and reinforce the die backside in applications such as Flip Chip, in which the die is mounted onto a substrate from the circuit surface. While protecting and reinforcing the die backside, it also blocks light to minimize effects on the circuit surface. Since this product comes as a tape, uniformity in thickness can be maintained through simplified operations. Lamination can take place at relatively low temperatures so that the risk of circuit damage from heat is reduced.
