The company's products are currently on the Chinese market using a "eutectic" packaging technology products, 28mil wafer chip can use a large current of 1.2A, Fang Fang imitation can not and can not use such a large current, otherwise it will soon burn. (For more information about "eutectic" packaging technology, please request and refer to our "eutectic" process data).
The advantages of the 28mil eutectic process LED are:
First, the brightness of more than "imitation" * 42mil products. (Measurement of brightness immediately) * As for the company's statement, we first introduced the "matrix type" infrared LED in 2009. One year later, imitations have appeared one after another. Now there is a general market in the market.
Second, the life expectancy is slightly longer than the 42mil product encapsulated in silver paste. (A large number of different company's experimental data can prove, and welcome customers to do 720 hours of light failure experiments to prove the length of life)
Third, the quality is much higher than the silver glue encapsulated 42mil products. (The packaging equipment and materials are far better than the Fang Fang imitation products, and the defect rate is controlled below 0.1%)
Fourth, the price is lower than the 42mil products in the Fangfang imitation silver plastic package.
Many people assume that the chip is bright, the chip can carry a large current, and the chip has a long life. In fact, this is wrong. In fact: heat dissipation determines the current, and the current determines the brightness, regardless of the size of the chip. LED products made by the same size chips have a different effect from day to day. It is like: Because of the different technologies and methods of engine design and manufacturing, the power and function of the Ferrari 1500cc is stronger than that of the BYD 3000cc. Also, due to differences in packaging technology and materials, our eutectic packaged 28mil LEDs outperform rivals' silver-encapsulated 42mil LEDs in brightness and lifetime. Of course, being able to persuade yourself is the result of self-experimentation, and the experimental data will speak.
What is the difference between our products in packaging technology and materials and Fang Fang imitation?
First, we are a national manufacturer of LED using eutectic packaging technology, the rest are using traditional silver plastic packaging method, the difference between the two thermal resistance is more than 3 times, the cooling rate is greatly different, the heat dissipation area of ​​the Fangmi 42mil silver plastic package Although it is more than twice as big as our new 28mil product, under the same current of 1.2A, everyone's brightness is slightly the same, and the heat generated is also slightly the same, but because our heat treatment is faster (less thermal resistance) and does not reduce at all Life is even longer. We can provide dozens of peer experimental results to prove that our 28mil chip can not only use the 1.2A high current, and the light failure is also slightly less than the imitation 42mil. It is recommended that your company can do the same test to convince yourself that we are willing to supply experimental samples for free.
Second, in addition to eutectic technology, in fact, we have adopted a newer packaging method and materials, making our LED at the same current, the brightness of imitation products is about 1.3-1.5 times stronger, you can immediately use the "infrared illuminance meter "And confirmed by the naked eye.
Third, the packaging of equipment and materials determines the quality of the LED, welcome to visit our packaging equipment at any time, and call your company also asked to visit other competitors' packaging factory for comparison. I believe that after your visit, you will highly appreciate our quality. This is the reason that the quality of the company's products has been recognized in the market for the past few years. Today, there is no change in the quality of the new 28mil and the original 42mil.
Conclusion: The eutectic process LED has the same brightness as the silver paste process LED, and its lifetime is longer than twice (because the heat treatment is different), or its life is the same and the brightness is more than 1.5 times stronger.
