Promerus has developed materials with unique property sets for wafer level packaging applications as part of its Avatrel® Materials program. These materials have been designed for stress compensation, passivation and electrical redistributionAvatrel2585P_Wafer_Image.jpg applications. Clear advantages of this family include:

  • Direct photo-imaging
  • Thick film ability
  • Very low stress
  • Low dielectric constant
  • Low moisture absorption
  • High glass transition temperature
  • Low temperature cure
  • Excellent transparency
