Nitto Denko’s ELP UE-115AJR


1. Product Overview

Nitto Denko’s ELP UE-115AJR is a UV-expandable tape designed for semiconductor applications. It features excellent chipping performance, controlled adhesion reduction after UV irradiation, and compliance with the RoHS2 directive. The tape consists of a PVC base film, acrylic adhesive, and PET liner, ensuring high performance in wafer processing.

2. Applications

  • Wafer dicing: Provides strong adhesion before UV exposure, securing wafers during cutting.
  • Die separation: After UV irradiation, adhesion reduces significantly, allowing for easy die pick-up.
  • Semiconductor processing: Ideal for precision applications requiring controlled adhesion and clean removal.
