Flip chip technology how to change the LED industry

Recently, burns worldcom photoelectric co., LTD., general manager of Lin Yujie share the application advantages of flip chip and packaging development trend in the future.

He said, flip chip chip has 10 times the point electrode size, metal surface welding, stronger welding strength, low thermal resistance, the rated working voltage is close to the theoretical value of 2.8 v; At the same time, the sapphire surface light, the external quantum efficiency is higher, allows the phosphor powder spraying, no gold, no stent, allow more than 2 times of current injection, etc.

The obvious advantages of flip chip chip in lighting applications, has a higher ratio of (lumens/RMB), higher reliability, more light Angle, higher luminous density, system costs down, shorten the manufacturing process, easy to gauge
