IC carrier: generally, it is a board on the chip. The board is very small, generally, it is 1/4 nail cover size, and the board is very thin 0.2-0. The material used is FR-5, BT resin, and its circuit is about 2mil / 2mil. For high-precision boards, it used to be produced in Taiwan, but now it is developing to the mainland.
The IC carrier board is mainly used to carry the IC, and there are lines inside to conduct the signal between the chip and the circuit board. In addition to the function of the carrier, the IC carrier board also has a protection circuit, a dedicated line, a heat dissipation path, and a component module. Standardization and other additional functions.
