Underfill

ALPHA® HiTech™ Underfills are one component, heat curable materials. They are epoxy based materials to be dispensed on the edges of the BGA, CSP or Flip Chip devices. The material then flows beneath the component through capillary action.  Upon completion of the curing process, the cured underfill helps strengthen the soldered assembled component allowing it to pass reliability tests such as Drop Shock, Impact Bend and Thermal Cycle (TCT).

 

ALPHA® Hi-Tech™ Underfills are designed for application in Automotive, Smartphone, Tablet, Notebook, and other portable related products. Users of the ALPHA® Hi-Tech™ Underfills can benefit from the following key product features:

  • Excellent Adhesion to FR4
  • Fast Flow / Penetration
  • Fast Curing Performance
  • Excellent Drop Shock
  • Reworkable
  • Halogen Free
