Adhesive Film FALDA™ Epoxy Heat Cure Type Adhesive Film
Long-term High Heat Resistance TypeFALDA™

Through use of special thermoplastic resin with long-term heat resistance and a thermosetting resin polymer alloy technology principally consisting of epoxy, we have implemented unprecedented long-term heat resistance reliability of over 1,000 hours at 175°C.

Power Device Applications
Ideal for power devices and automotive ICs/electronic components that are used for long periods under high heat.
Adhesive Film
Electronic Component Applications
High stress mitigation and excellent high heat resistance make it ideal for MEMS and chip sealing.
Adhesive Film


  1. Compared to standard epoxy resin, there is little deterioration at high temperatures of 150°C to 175°C.
  2. With high stress mitigation, it follows the unevenness of chips well when laminating.
  3. Superior flexibility mitigates the CTE mismatch generated when adhering disparate materials.
