What is Flip chip?

Flip chip, also known as controlled collapse chip connection or its abbreviation, C4, is a method for interconnecting semiconductor devices, such as IC chips and microelectromechanical systems (MEMS), to external circuitry with solder bumps that have been deposited onto the chip pads. The technique was developed by General Electric's Light Military Electronics Dept., Utica, N.Y. The solder bumps are deposited on the chip pads on the top side of the wafer during the final wafer processing step. In order to mount the chip to external circuitry (e.g., a circuit board or another chip or wafer), it is flipped over so that its top side faces down, and aligned so that its pads align with matching pads on the external circuit, and then the solder is reflowed to complete the interconnect. This is in contrast to wire bonding, in which the chip is mounted upright and wires are used to interconnect the chip pads to external circuitry.

Advantage of the Flip chips COB LED:

Wireless bonded LED technology, often referred to as flip chip, offers several key performance benefits over traditional SMT (Surface Mount Technology) LEDs including enhanced durability, enhanced heat dissipation and superior light performance Flip chip LEDs provide superior light performance compared to conventional LED technology.

Higher light oulput is achieved in a more compact space and the light performance is not disrupfed by shadows or other obstacles to consistent performance.

With wireless bonded technology the chip can directly emit light from the top and the side with no wire bond casting shadows or creating uneven light distribution, providing 15% more light output.
