AlN Laser Diode Carriers - Pre-deposited AuSn
Description
For laser mounting a thin layer of vacuum-deposited AuSn can be selectively applied over conductor areas. The standard alloy ratio is nominally 76Au/24Sn, normally at ~4-5 microns thick. On reflowing, the Au in the underlying conductor and on the underside of the laser chip, combine with the pre-deposited solder to form an alloy approximating to the eutectic ratio of 80Au/20Sn. The resulting alloy flows and wets very well to both the laser and the carrier, resulting in excellent low-void joints minimising thermal resistance and hotspots. The alloy ratio can also be tailored for specific applications.
