Flip chip technology is currently very popular concept, its advantages I believe we all understand. But the biggest reason why it is not yet universal is twofold:
First, how new technologies will take some time to explore will be formed, and ultimately the market will determine his life.
Second, the flip-LED subverts the traditional LED technology, from the chip until the package, this will require higher equipment, take the package that can do flip-chip front-end equipment costs will certainly increase a lot, which set The threshold, so that some companies simply can not come into contact with this technology.
Chip flip chip technology is one of APT's core technologies
Chip flip technology advantages:
Flip chip and flip chip compared with the loading, it has better heat dissipation; the same time, we have to adapt and flip-chip epitaxial design, chip technology, chip graphics design. Chip products with low voltage, high brightness, high reliability, high saturation current density and other advantages; coupled with the flip chip can be integrated in the protection of the substrate circuit, the chip reliability and performance significantly help; In addition, Compared with the vertical structure, the use of flip-chip, easier to achieve ultra-high power chip-level module, a variety of integrated chip light source technology, LED chip module yield and performance have greater advantages.
LED light on the modular concept
What is LED light source module? LED light source, cooling components and drive power assembly molding, integrated to complete the "light, electricity, heat," highly integrated assembly. This move makes the product simple and cheap, is the future development of semiconductor lighting a trend. Years ago, Chaoyi Lighting Division has introduced integrated LED driver chip. By modularizing the LED light source, the intermediate link from the chip to the system can be reduced. This whole process, abroad called: system package.
