Description

Technical Field

[0001] The invention relates to the technical field of lasers, in particular to a laser TO packaging eutectic platform. Background Art

[0002] After decades of development, semiconductor lasers have become increasingly familiar to society due to their advantages such as small size, light weight, high electro-optical conversion efficiency, long life and high reliability. They have gradually replaced traditional gas and solid lasers in the fields of communications, medical treatment, display, industrial production and security. The popularity and diversification of applications have made the market have higher and higher requirements for the packaging quality of semiconductor lasers.

[0003] At present, most semiconductor lasers in TO coaxial packaging use the gold-tin eutectic packaging process. The heat sink preform made of gold-tin eutectic alloy can be welded to the gold layer on the surface of the LD chip at 300-310°C without flux, and the solidification process is fast, which greatly shortens the welding cycle. At the same time, with other excellent properties, the gold-tin solidification process is currently widely used in semiconductor lasers in TO coaxial packaging. Because the gold-tin eutectic needs to be carried out in a high-temperature environment, the equipment currently packaged using the gold-tin process has a eutectic table structure that can be heated.

[0004] Most of the mature TO die bonding machines on the market can only perform gold-tin eutectic bonding on one specification of TO coaxial packaged semiconductor lasers. If you want to replace TO devices of other specifications, you need to replace multiple hardware structures such as the suction nozzle and eutectic table of the equipment. Replacing the hardware structure not only takes a long time to operate, but also requires subsequent debugging before it can be used. In addition, frequent replacement of the eutectic table will also cause the newly installed eutectic table to have problems such as inconsistent position and unstable equipment operation, thereby affecting the product quality of subsequent die bonding products. Summary of the invention

[0005] In response to the above problems, the present application provides a laser TO packaging eutectic table, which can simultaneously perform solid crystal packaging on the TO tube sockets commonly found on the market, thereby improving the working capacity of the equipment using the eutectic table structure and avoiding the current hardware debugging of switching products, which not only saves time but also avoids the problem of unstable state caused by various types of debugging of the equipment.
