Pcb printed circuit board, is a provider of electrical connection of electronic components. Its development has been more than 100 years of history; its design is mainly layout design; the main advantage of using circuit board is greatly reduce the wiring and assembly errors, improve the level of automation and production labor.
According to the pcb printed circuit board layer can be divided into a single panel, double-sided board, four board, six board and other multilayer circuit board.
Due to the printed circuit board is not a general terminal product, so slight confusion in the definition of the name. For example: personal computer motherboard, said board, can not be directly referred for the circuit board, although the main board circuit board, but is not the same. Therefore, the assessment industry when they are related but can't say the same. Another example: because there are integrated circuit parts loaded on the board, so the news media called him IC board, but in essence, he is not equivalent to the pcb printed circuit board. The pcb printed circuit board we usually refers to the circuit board that no bare board components.
Prior to the emergence of a pcb printed circuit board, the interconnection between the electronic components is to rely on the direct connection of the wire to form a complete line. At present, the circuit board is only as an effective experimental tool, and the printed circuit board has become the dominant position in the electronic industry.
Over the past decade, China's pcb printed circuit board (Circuit Board Printed, referred to as PCB) manufacturing industry developed rapidly, the total output value, the total output of both ranked first in the world. Due to the rapid development of electronic products, the price war has changed the structure of the supply chain, China has industrial distribution, cost and market advantages, has become the world's most important production base of pcb printed circuit board.
The pcb printed circuit board is developed from single layer to double sided board, multilayer board and flexible plate, and develops to high precision, high density and high reliability. Constantly reduce the volume, reduce costs, improve performance, making the pcb printed circuit board in the future development of electronic products, still maintain a strong vitality.
Future pcb printed circuit board production and manufacturing technology development trend in the performance to the high density, high precision, pore diameter, thin wire, small spacing, high reliability, multilayer, high-speed transmission, light weight, thin direction.
