Bench drill releases industry-leading high conductivity low expansion drill copper heat sink

Recently, Taiwan Diamond Co., Ltd., a well-known optoelectronics company, released a high-conductivity, low-expansion drilled copper heat sink. According to reports, this product currently has a relatively high technological process in China. According to the unique low thermal resistance and low coefficient of expansion of the diamond, the composite type of innovative copper-metal composite material has been applied to Foxconn's products and received good feedback. A good product requires more than just science. The detection and verification need to be verified through extensive use in practical applications. In any case, this product has positive and practical significance for the development of high-power LED products in current lighting applications, and has academic value.

Taiwan drillers said that as high-power LED applications continue to expand in the field of lighting, high-power LED heat dissipation has become a common problem, whether it is LED lights, car lights or large LED TV backlight heat is In order to solve this problem, this paper recommends to the reader a new type of drilled copper heat sink, which is a patented product (China Patent No.: ZL 03142946.7) and hopes that it can bring a new interpretation of LED heat dissipation.

It is reported that this product uses artificial diamond particles to penetrate copper into two layers of upper and lower alloys and diamond diamonds in the middle. This conforming material not only has a much higher thermal conductivity than existing copper and aluminum heat sinks, but its thermal expansion rate can be adjusted to make it closer to semiconductor chips. Such drilled copper heat sinks can be soldered directly to the chip to prevent heat flow from being blocked by the thermal paste. The use of drilled copper heat sinks in high power, high heat electronic products can solve the problem of heat dissipation.

According to reports, drilled copper heat sinks are mainly used in the following areas: 1. LED high-power street lamps and automotive headlight circuit boards can be far beyond the existing materials in the industry. 2. The thermal chips of the CPU and GPU in the notebook computer far exceed the existing materials in the industry in terms of thermal conductivity and thermal expansion rate. 3, large panel LCD TV LED backlight circuit board.
