Semiconductor Tapes and Materials
     


 

UV tapes differ from Non-UV tapes in that they must be exposed to a UV light source prior to removal. This makes it possible to achieve a higher tack during processing while ensuring ease of removal after exposure.

Features and Benefits of UV Tape:

Pre-Cure: Post-Cure:
  • Higher tack to secure wafer during aggressive grinding process
  • Good for non-standard substrates such as FR4 and BGA
  • Acid resistant versions available for etch processes
  • Effective in securing small die during dicing to prevent die movement and fly-off
  • Exposure to UV light source breaks adhesive bond, thereby facilitating easier tape removal
  • Low post cure tackiness reduces wafer breakage during detaping; a benefit in thin wafer applications
  • Leaves wafer surface free of impurities, contamination, and other residue.
  • Facilitates easy die removal during pick & place operations

Features and Benefits of Non-UV Tape :

  • Good for standard grinding and dicing applications
  • Cost effective
  • Lower tack values for applications that can not withstand aggressive adhesion
  • Bypass additional process time associated with UV curing
