Matsushita Electric as well as KYOCERA chemical have exhibited LED packaging materials

In the eleventh semiconductor packaging technology exhibition (January ~ 22 and the same time the INTER NEPCON JAPAN held on the same day), Matsushita Electric, and KYOCERA, such as a reference to the LED packaging materials. The LED market is expanding rapidly due to LED lighting products and LCD panel backlight. Especially in the LED lighting products, improve the brightness of LED has become one of the focal points of technology development. Thus the emergence of high heat dissipation and high reflectivity of the LED substrate material as well as the high rate of packaging materials, such as demand, the manufacturers have exhibited a response to accelerate the attitude.

Matsushita Electric exhibits a high heat dissipation floor material for LED lighting products, ECOOL". In addition to the thermal conductivity of 1W/mK has been put into operation, R-1787, 3W/mK, the company also reference exhibits thermal conductivity of up to 2W/mK and the bottom material. These floor materials can support 2W and 3W LED. In the thermal analysis experiment of the floor material, the LED temperature increases to 49.1 DEG C when the thermal conductivity is 0.4W/mK FR-4. While the thermal conductivity of R-1787 can be reduced to 36.5 1W/mK floor. In this experiment, the 1mm thick plate with 50mW LED was adopted.

As the company's liquid crystal polymer thin film material Vecstar new product group, Li Li exhibited a high reflectivity of the substrate can be used for the development of LED FB". The reflectivity of light at the wavelength of 470nm is as high as 80%, and can be maintained at a temperature of 150 DEG C for about 1000 hours at the temperature of 4 DEG C or at a temperature of 200 DEG C, and the reflectivity can be maintained by a factor of 80%. The company also references the mount a motor with the thin film material manufactured 200 m thick ultra-thin LED surface packaging backplane.

KYOCERA chemical reference exhibits a higher optical transmittance of the LED with a package resin. There are two types of solid and liquid, the wavelength of 460nm light transmittance, the solid type is 90%, liquid type is 91%. 85% higher than that of the common packaging material. Solid support transfer (Transfer) molding machine and compression molding machine.
