[Text|High-tech LED reporter Xiong Yuheng] At present, LED packaging methods mainly include planar packaging and die-top packaging. Because of its simple operation and low packaging cost, planar packaging is widely used by small and medium-sized packaging companies. However, the drawback of this packaging method is that the light efficiency and luminous flux are low, which is not comparable to the products packaged by the lens packaging process.
The die top package belongs to the traditional lens packaging process. The encapsulant is injected into a hemispherical lens mold, heated and solidified, and then demolded to form a hemispherical lens. However, the process is complicated in operation and the packaging cycle is long, and at the same time, the huge equipment investment leads to high production cost, and the ordinary packaging enterprise cannot bear it at all.
Therefore, how to find a new lens packaging process with simple process, low cost and suitable for large-scale production has become a difficult point for every packaging enterprise to break through.
“The LED thixotropic methyl silicone rubber developed by Anpin has changed the current die-packaging process in the LED lens package, which provides a new lens packaging process for packaging companies, which can solve the problems of the traditional packaging mode. "Ding Xiaowei, Chairman of Shenzhen Anpin Silicone Materials Co., Ltd. (hereinafter referred to as "Anpin Silicone") mentioned.
Anpin Silicone is committed to the research, development, production and operation of silicone products. The company's products cover silicone oil, silicone rubber, silicone resin, cable refractory materials and silicone modified materials, water-based emulsions, etc., especially in LED packaging materials. It has a high level of research and development and production of thermal conductive materials.
According to Ding Xiaowei, Anpin LED thixotropic methyl silicone rubber can be directly injected onto a flat substrate by adding a new type of silicone thixotropic agent. No mold is needed to achieve mold-free packaging, simplifying mold processing and installation in the mold top process. , injection molding, high temperature curing with mold, peeling mold, etc., the process is simple and the light efficiency and luminous flux are much higher than the planar package.
At the same time, the product can also achieve 360-degree illumination, greatly improving the light efficiency. "Our LED thixotropic methyl silicone rubber has been close to or even surpassed similar products at home and abroad in terms of thixotropy, extrudability, light transmittance, anti-aging, adhesion and other technical indicators. In 2013, the company's LED thixotropic type A Base silicone rubber accounts for 40% of the market in its class," Ding Xiaowei said.
The 2014 (5th) High-tech Golden Globe Awards - the annual LED good product selection has entered the WeChat voting stage: August 1st - 7th is the pre-registration time, August 8th - September On the 30th, it will enter the official voting stage of WeChat. This product of silicone will carry the above-mentioned LED thixotropic methyl silicone rubber to compete for the 2014 Golden Globe Award.
Ding Xiaowei is very optimistic about the application prospect of this product in the LED packaging industry. "LED thixotropic methyl silicone rubber is not only easy to operate, but also simple in process, low in cost and high in production efficiency. It is more suitable for mass production and more important. It is the patented technology of the product, and it is expected to break through the technical barriers and enter the international market."
