Alpha Launches PowerBond Preforms for Increased Strength and Thermal Fatigue Resistance


Reading time ( words)

Alpha Assembly Solutions, the world leader in the production of electronic soldering and bonding materials, has recently introduced ALPHA PowerBond Solder Preforms for high temperature, high reliability, lead-free interconnects for automotive and power semiconductor applications.

“ALPHA PowerBond Preforms contain approximately 5-10% of antimony (Sb), which enable solder joints to have increased strength, thermal fatigue resistance and higher liquidis temperatures, compared to traditional tin/silver/copper-based lead-free systems," said Gyan Dutt, global portfolio manager for Die Attach Solutions at Alpha Assembly Solutions, a part of the MacDermid Performance Solutions Group of Businesses. “These preforms can also be customized with ALPHA TrueHeight Preforms technology for bond-line thickness and tilt control or can be pre-coated with ALPHA AccuFlux, an ultra-low voiding flux formulation, for difficult-to-solder surfaces."

  • ALPHA PowerBond 2110 Preforms balance high creep resistance of Sn90Sb10 system with high thermal conductivity required for power semiconductor devices.
  • ALPHA PowerBond 2100 Preforms provide highest creep resistance and tensile strength for high operating temperature applications.
  • ALPHA PowerBond 2050 Preforms expand upon industry standard Sn95Sb5 alloy to provide improved wetting characteristics.
