Shin-Etsu Chemical Co., Ltd. develops packaging materials for LEDs that reduce gas permeability

Under the conditions of maintaining light resistance and heat resistance, the ASP series reduces the shortcomings of silicon materials - gas permeability. As a packaging material for LEDs, the gas permeability is reduced to about 1/100 of the methyl silicon used previously and about 1/10 of that of phenyl silicon. As a result, it is possible to prevent the intrusion of oxygen in the air, thereby preventing oxidative corrosion of the peripheral parts of the LED chip. Its refractive index is as high as 1.57, which can improve the light extraction rate. For the product, "ASP-1010A/B" having a hardness of 55 (SHORED) and "ASP-1020A/B" having a hardness of 65 (Durometer A) are available.

Investment Casting II

Investment Casting, also known as lost wax casting, includes wax pressing, wax repairing, tree formation, paste, wax melting, casting metal liquid and post-treatment processes. Lost wax casting is the process of making a wax mold of the part to be cast, and then coating the wax mold with mud. After the clay mold is dried, melt the wax mold inside in hot water. Melt the wax mold out of the clay mold and then roast into pottery mold. Once roasted. Generally, a casting port is left when the mold is made, and then molten metal is poured into the pouring port. After cooling, the required parts are made.
