We offer various tapes.

Backside Coating Tape LC Tape

LC Tape

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.

  1. 1. This is a special adhesive tape that reduces damage to the circuit surface by blocking off light at the same time that it protects and reinforces the die backside. Featuring both high quality and stability, the tape has passed reliability tests in environments of high temperature and humidity.
  2. 2. Unlike a coating of liquid mold material, this product is available as a tape, ensuring outstanding uniformity in thickness, and allowing the simplification of conventional processes.
  3. 3. Since laminations can be done at relatively low temperatures, damage to circuit from heat is reduced. Can be used with Lintec's high performance laminator (RAD-3600F/12) for tape lamination, which in turn contributes to the structuring of highly reliable production lines.
  4. 4. The tape is laminated to the die backside before dicing, which helps prevent wafer chipping during dicing.
  5. 5. Laser markings such as the manufacturer's name or lot number can be inscribed on the tape's backside.
