The Japanese developed can meet the requirements of high power LED module

Japan Tanaka Kikinzoku Industrial Company and S.E.I company announced on April 4, 2016, containing gold particles (0.1 M) of the low temperature bonding material "AuRoFUSE", developed can meet the requirements of high power LED module. Effect of LED lighting in light of the heat, the output power will decrease, therefore, how to improve the existing LED module heat dissipation problem. While the new product solves this problem.

The specific method is that using AuRoFUSE as bonding material for flip chip bonding, rather than the current mainstream of wire bonding. Flip chip bonding is the terminal protrusions (bumps) chip is connected to a lead frame and method of substrate in electrical mode, directly to the LED chip bonding to the substrate as a light emitting surface heat near the substrate, it is easy to make the heat. In addition, by removing the lead, not only can save the space occupied by the lead, the realization of miniaturization, but also can improve the electrical characteristics.

However, in the past for flip chip bonding, must use expensive aluminum nitride on a substrate. This is because the expansion coefficient of metal substrate and LED chip low price hot there is a big difference, the joint is easy to damage. In this technique, containing gold particles as the bonding material of AuRoFUSE, these gold particles can ease the deformation of thermal expansion, we can use the metal substrate with low price. With this technology, high output power and miniaturization can be realized LED module.

Tanaka Kikinzoku will be in April 6, 2016 in Tokyo Ming International Convention and Exhibition Center held a "Japan third high functional metal show", through the company's booth display module the LED. The future goal of the company is, the LED module uses extended to the import and export of frozen warehouse and can use the advantages of miniaturization of vehicle lighting etc..
