Silver has many desirable material properties, such as high thermal conductivity, low modulus, low electrical resistance, and a significant capability to withstand power cycling strain, but its melting temperature (962 degrees C) presents a challenge as a die attach material. By creating nano particles, silver can be processed at solder-like temperatures (200-300 degrees C), provided some pressure is used. The process is referred to as sintering. Power cycling tests comparing soldered and wirebonded IGBT devices with sinter silver attach devices have shown more than an order of magnitude improvement in cycles to failure, while the sintered device is switching +50% more current without an increase in die temperature. Material solutions such as paste, film and preform are available to address a wide variety of customer design requirements. Surface finishes supported include gold, silver and copper. Join this webinar to learn how Alpha's Argomax(R) has made significant impact in electric vehicle inverter designs. Alpha has developed a number of equipment partners that can provide production volume support. The company has also established customer support centers globally to support customers interested in evaluating sinter silver materials in their applications.
