An integrated circuit generally refers to the integration of a chip, such as a north bridge chip on a motherboard. Inside the CPU, it is called an integrated circuit, and the original name is also called an integrated block. The printed circuit refers to the circuit board we usually see, and the solder chip is printed on the circuit board.
The integrated circuit (IC) is soldered on the PCB; the PCB version is the carrier of the integrated circuit (IC). The PCB board is a printed circuit board (PCB). Printed circuit boards appear in almost every electronic device. If there are electronic parts in a certain device, the printed circuit boards are mounted on PCBs of various sizes. In addition to fixing various small parts, the main function of the printed circuit board is to make electrical interconnections between the various parts above.
Simply put, an integrated circuit integrates a general-purpose circuit on a chip. It is a whole. Once it is damaged inside, the chip is damaged. The PCB can solder components themselves. If it is broken, the components can be replaced.
