1, integrated circuit generally refers to the integration of chips, such as the northbridge chip on the motherboard and the internal CPU, all of which are called integrated circuits, formerly known as integrated blocks. Printed circuit refers to the circuit board we usually see, and the solder chips printed on the circuit board.

2. The integrated circuit (IC) is soldered on the PCB; PCB is the carrier of integrated circuit. PCB is a printed circuit board (PCB). Printed circuit boards will appear in almost every kind of electronic equipment. If there are electronic components in a device, then printed circuit boards are embedded in PCBs of different sizes. In addition to fixing various small parts, the printed circuit board is mainly used to electrically connect the above parts.

3. Simply put, an integrated circuit is to integrate a general circuit into a chip, which is a whole. Once the inside is damaged, the chip will be damaged, and the PCB can weld components by itself. If it is broken, it can be replaced.

Extended data:

PCB, that is, printed circuit board, is one of the important components of electronic industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers, communication electronic equipment and military weapon systems, as long as there are electronic components such as integrated circuits, printed boards are used to electrically interconnect the components.

Printed circuit board (PCB) is composed of insulating bottom plate, connecting wires and bonding pads. It is used to assemble and weld electronic components and has the dual functions of conducting wires and insulating bottom plate. It can replace complex wiring and realize the electrical connection between components in the circuit, which not only simplifies the assembly and welding of electronic products, but also reduces the workload of traditional wiring and greatly reduces the labor intensity of workers. But also reduces the volume of the whole machine, reduces the product cost and improves the quality and reliability of electronic equipment.

An integrated circuit is a micro electronic device or component. Using a certain process, the components and wiring needed in the circuit are connected together, made on a small piece or several small pieces of semiconductor wafer or dielectric substrate, and then packaged in a package to form a microstructure with the required circuit function; All the components are integrated in structure, which makes electronic components take a big step towards miniaturization, low power consumption, intelligence and high reliability. It is represented by the letter "IC" in the circuit. Inventors of integrated circuits are jack kilby (Ge-based integrated circuits) and robert noyce (Si-based integrated circuits). Today, most applications in the semiconductor industry are silicon-based integrated circuits.
