The difference between circuit board and chip

Many people think of a circuit board as a chip, but the two are fundamentally different.

Chip, also known as IC, refers to all electronIC components in general. It is a circuit module that integrates a variety of electronic components on a silicon board to achieve a specific function. It is the most important part of an electronic device, carrying out computing and storage functions. In the computer world, the chipset is usually referred to as the chip in the computer motherboard or expansion card, equivalent to the engine in a car.

The PCB in Circuit Board design refers to the Printed Circuit Board, the Chinese name is printed circuit board is an important electronic component, is the support body of electronic components, is the carrier of electrical connection of electronic components. Because it is produced by electronic printing, it is calLED "printed" circuit board.

 PCB circuit board

Electronic equipment using printed board, because of the consistency of SIMilar printed board, so as to avoid the error of manual wiring, and can realize the automatic insertion or installation of electronic components, automatic soldering, automatic detection, to ensure the quality of electronic equipment, improve labor productivity, reduce costs, and easy maintenance.

Taking four-layer printed board as an example, the production process mainly includes PCB layout, core board production, inner PCB layout transfer, core board drilling and inspection, lamination, drilling, copper chEMIcal precipitation of hole wall, outer PCB layout transfer, outer PCB etching and other steps.

The production difficulty of the chip is like doing space rocket, PCB circuit board is to do the car, the difficulty of making the chip is higher.

One, the plate is different

1, circuit board: the board of the circuit board has ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency plate, thick copper plate, etc.

2. Chip: A chip is a circuit manufactured on the surface of a semiconductor wafer sheet.

Two, the number of layers is different

1. Circuit board: According to the number of layers, the circuit board is divided into single panel, double panel, and multi-layer circuit board.

2, chip: chip is integrated substrate and circuit board composed of double-sided miniaturized circuit panel.

Three, different uses

1, the circuit board is on the insulating substrate, according to the predetermined design of the formation of connecting wires from point to point and printed components of the printed board. As the support of electronic components and the electrical connection carrier of electronic components, in other words, the existence of the circuit board is to assist electronic components to better play their due performance.

2. Chip is the general name of semiconductor component products. It is the carrier of integrated circuit, which is segmented by wafer. Chipset mainly determines the function of the motherboard, and then affects the performance of the whole computer system. It is the core component of the motherboard.
