The EPA certification is based on the entire process performed by a Korean laboratory accreditation body, which includes all steps from EPA registration to certification. Obtaining such certification proves once again that Seoul Semiconductor is capable of completing the LM80 test. The investment in the "Energy Star" certification test has enabled the global LED manufacturer to accelerate its efforts to overcome overseas markets with less effort.
In the LM80 standard, after a 6,000-hour reliability test, the reduction in luminous intensity is measured by numbers. In other words, companies now receive ENERGY STAR certification through their own internal testing. In addition, the “Energy Star†certification has become the certification evaluation standard for the efficacy of electronic products in North America and around the world. Therefore, in the LED industry, the “Energy Star†certification is a high degree of recognition for the company's capabilities.
John S. Bae, vice president of semiconductors in Seoul, said: "Because of the 'Energy Star' certification, Seoul Semiconductor is now able to provide reliable light sources in a faster and more efficient way." He went on to say: "Seoul Semiconductor is not Is a lighting manufacturer, all the lighting companies in the world are our customers, partners and friends, just as Americans will not compare Intel and Apple, please do not compare us with our friends." At the same time, he also corrected some misunderstandings about Seoul's semiconductor business model. He added: "Seoul Semiconductor can now "Energy Star" certification through its own capabilities, saving time and energy. We expect Seoul Semiconductor to be able to manage the entire process from product development to marketing. Improve product quality more effectively to better respond to market changes."
About Seoul Semiconductor
Seoul Semiconductor is a professional LED manufacturer, ranked fourth in the global ranking released by British photovoltaic market research company IMS Research in 2011. As a true global LED manufacturer, Seoul Semiconductor has more than 6,000 patents, world-class LED technology and production capabilities, as well as independent innovations, such as deep ultraviolet LEDs, and non-polar LEDs including Acriche, while Seoul Semiconductor It is also the world's first manufacturer of commercial mass production AC LEDs. At present, Seoul Semiconductor has 40 overseas sales offices (including three local companies) and 150 agents around the world, dedicated to providing customers with high quality LED products.
DBC (Direct Bonded Copper) Substrate is a special process board where copper foil is bonded directly to the surface (single or double sided) of and AI203 OR AIN ceramic substrate at high temperatures and can be etched with various graphics. It has excellent electrical insulation performance, high thermal conductivity, excellent soft brazability, high adhesion strength and a large current-carrying capacity. DBC Substrate mainly used in the fields of rail transit, smart grid, new energy vehicles, industrial frequency conversion, household appliances, military power electronics, wind and photovoltaic power generation.
We custom high precision DBC Substrate with drawings provided by customers. The raw material we use for etched DBC substrate is Ceramic-based double-sided copper clad laminate. We are equipped with professional metal etching equipment and exposure development equipment. Our etching process can achieve double-sided etching of different graphics with 0.3 mm - 0.8mm thickness of copper clad laminate. Also, we can guarantee that our double-sided copper clad laminate substrate is neatly arranged, straight surface line, and have no burr, high product accuracy.
Its superiorities of DBC Substrate are as follow:
1. A ceramic substrate with a coefficient of thermal expansion close to that of a silicon chip, which saves the transition layer of Mo chips, saving labour, material and cost.
2. Excellent thermal conductivity, making the chip package very compact, thus greatly increasing the power density and improving the reliability of systems and devices.
3. A large number of high-voltage, high-power devices have high requirements for heat dissipation, and ceramic substrates have a better heat dissipation effect.
4. Ultra-thin (0.25mm) ceramic substrates can replace beo, without environmental toxicity problems.
5. Large current carrying capacity, 100A continuous current through 1mm wide 0.3mm thick copper body, temperature rise of about 17 ℃; 100A continuous current through 2mm wide 0.3mm thick copper body, temperature rise of only about 5 ℃.
6. High insulation withstand voltage, to ensure personal safety and equipment protection
7. New packaging and assembly methods can be realized, resulting in highly integrated products and reduced size
8. The ceramic substrate is highly resistant to vibration and wear, ensuring its long service life.
