One of the most highly demanded applications for 80Au20Sn is semiconductor laser die-attach due to recent advancements that have made lasers an economical option for a multitude of new products. However, a key challenge with semiconductor lasers is thermal management, as these devices generate a significant amount of heat. Indium Corporation Product Specialist Jenny Gallery will present on how to manage heat with AuSn preforms at SPIE Photonics West, Jan. 22-27, San Francisco, Calif., U.S.
One method for facilitating thermal transfer from the die to the substrate is to reduce the bondline thickness through the use of thinner 80Au/20Sn preforms. By using a thinner preform in the bondline, the heat is transferred away from the die more quickly,
increasing the longevity and potential of the die. In The Effect of AuSn Preform Thickness on Thermal Transfer in Semiconductor Laser Technologies, Gallery will examine the impact of AuSn preform thickness on thermal transfer by examining voiding percentages on several 80Au/20Sn preforms ranging from 0.002” to 0.00035” thick.
