What is the PCB?
PCB (Printed Circuit Board), known as Printed Circuit Board, also known as Printed Circuit Board, is an important electronic component, which is the support body of electronic components and is the carrier of electrical connection of electronic components.Because it is made of electronic printing, it is called "printed" circuit board.
Electronic equipment adopts the PCB, due to the consistency of the same kind of PCB, so as to avoid the artificial connection error, and can realize automatic instrumentation or SMT electronic components, automatic soldering, automatic detection, ensure the quality of the electronic equipment, improve the labor productivity, reduces the cost, and easy maintenance.
The printing plate develops from single layer to double-sided, multi-layer and flexible, and still maintains its own development trend. Due to constantly to develop in the direction of high precision, high density and high reliability, shrinking volume, reduce costs, improve performance, makes the PCB in the future development of the electronic equipment engineering, still maintained a strong vitality.
We're reviewed at home and abroad in the future technology development trend of PCB manufacturing is basically consistent, namely to high density, high precision, small aperture, thin wire, small spacing, high reliability, multiple stratification, high-speed transmission, light weight, thin, on the production at the same time to improve productivity, reduce costs, reduce pollution, to adapt to many varieties, small batch production.The technical development level of the printed circuit is generally represented by the line width, aperture, plate thickness/aperture ratio of the printed board.
