Difference:PCBis printed circuit board vs ICis an integrated circuit.
Integrated Circuit i s a general circuit integrated into a chip, it is a whole, once it is damaged, then the chip is damaged. PCB can weld components by itself, and the components can be replaced when broken.
IC board: generally chip on the board, the board is very small, generally on the size of 1/4 nail, the board is very thin 0.2~0. 4mm, the material is FR-5, BT resin, pttern size is about 1mil/1mil. For the high precision board, before the general production in Taiwan, and now to the mainland development trend.
PCB board: is our mobile phone, computer and the surrounding board, there are N-book board, memory, LCD, H-DI and other boards, features: Board is generally around 1.0, pattern size is 3mil / 3mil. (feel can not do 2/2, process is not the same) material fr-4, epoxy resin, now belongs to the cheap PCB
