BondFlow™ Adhesive

BondFlow™ is a revolutionary, new die attach adhesive. It can be applied onto the backside of a wafer and B-staged prior to wafer singulation. This backside die attach adhesive will cure in only 2 seconds under 50 – 100 psi pressure at 250°C.

Materion Delivers

The benefits of BondFlow™: Our unique adhesive can be spin-coated or printed onto a wide variety of surfaces. It adheres well to bare ceramics, silicate (window) glass, CVD diamond and Al, Au, Ni, Si and GaAs.

  • Spin-coated layers have excellent thickness uniformity
  • B-staged layer is non-tacky with long shelf life at room temperature
  • B-staged coating cures on a hot plate at 250°C after only 2 seconds
  • Pressure during cure: 50 to 100 psi (340 to 690 kPa)
  • Minimal squeeze-out and tilt
  • Cured bond retains adhesion strength even after 3 minutes at 400°C
  • Multiple dice can be bonded in sequence without any movement of each die after cure, (similar to AuSn)
  • Thermal conductivity of 2.4 W/m-K.
  • Cured bondline thickness 3 to 20 µm.
  • Dielectric BondFlow™ also available, with breakdown strength of 140 V/µm
