The difference between PCB printed circuit board and integrated circuit:
1. Integrated circuits generally refer to the integration of chips, such as the north bridge chip on the motherboard, and inside the CPU, they are all called integrated circuits, and the original name is also called integrated blocks. The printed circuit refers to the circuit boards we usually see, as well as printing and soldering chips on the circuit board.
2. The integrated circuit (IC) is welded on the PCB board; the PCB board is the carrier of the integrated circuit (IC). The PCB board is a printed circuit board (Printed circuit board, PCB). Printed circuit boards are found in almost every electronic device. If there are electronic parts in a certain device, 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 electrically connect the various parts above.
3. To put it simply, an integrated circuit integrates a general-purpose circuit into a chip. It is a whole. Once it is damaged inside, the chip will also be damaged, and the PCB can solder components by itself. If it is broken, it can be replaced. element.
PCB is a printed circuit board, referred to as a printed board, and is one of the important components of the electronics industry. Almost every kind of electronic equipment, ranging 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, in order to make the electrical interconnection between various components, printed circuit boards must be used. plate.
The printed circuit board is composed of an insulating base plate, connecting wires and pads for assembling and welding electronic components, and has the dual functions of a conductive line and an insulating base 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, reduces the workload of wiring in traditional methods, and greatly reduces the labor intensity of workers; it also reduces the size of the whole machine. Volume, reduce product cost, improve the quality and reliability of electronic equipment.
An integrated circuit is a tiny electronic device or component. Using a certain process, the transistors, resistors, capacitors, inductors and other components required in a circuit are interconnected, and they are fabricated on a small or several small semiconductor wafers or dielectric substrates, and then packaged in a tube. , and become a microstructure with required circuit functions; all the components in it have been structurally integrated, making electronic components a big step towards miniaturization, low power consumption, intelligence and high reliability. It is represented by the letter “IC” in the circuit. The inventors of the integrated circuit are Jack Kilby (germanium (Ge)-based integrated circuits) and Robert Noyce (silicon (Si)-based integrated circuits). Most of today’s semiconductor industry uses silicon-based integrated circuits.
