Ultraviolet Dicing Tape ProFilm DU177E

Wafer Dicing Tape

ProFilm™ DU177E is a protective surface film designed to deliver consistent, precise and repeatable wafer production yields. Enhanced with superior ultraviolet adhesive coating technology, ProFilm™ DU177E offers Total Thickness Variation (TTV) control, expandable base film, and a special low extractable release liner that reduces silicon residue by a significant margin.

  • Specially formulated polyolefin film for unparalleled protection
  • Coated with stable UV curable pressure-sensitive adhesive
  • Features expandable chloride-free base film
  • Easy die removal post ultraviolet light exposure
  • Film minimizes or eliminates die rocking and other picking defects
  • Film is transparent and untinted to help human and electronic vision die defect recognition

ProFilm™ DU177E is constructed in three layers:

  • Polyolefin Base Film (6.0Mils)
  • UV Sensitive Adhesive (1.0Mils)
  • Release Film (0.92Mils)

ProFilm™ DU177E is available in a variety of configurations. Standard widths include 200mm, 230mm, 250mm, 275mm, 300mm, 330mm and 400mm. Rolls are provided in splice free lengths of 100m on a 3” I.D. plastic core. Both custom widths and lengths may be available by special request. ProFilm™ DU177E rolls are polybag wrapped and individually boxed.
