What is pcb stand for?It is short for "Circuit Board Printed", it is an important electronic component, it is the support of electronic components, it is the carrier of electronic components electrical connection. Because it is made of electronic printing, it is called the printed circuit board.

   What is pcb stand for?What is its function?After the electronic device uses the printed board,due to the consistency of the same kind of printed boards, the error of manual wiring can be avoided, and the electronic components can be automatically inserted or installed, automatic solder and automatic detection, which ensures the quality of the electronic equipment, improves the labor productivity, reduces the cost, and is convenient for maintenance.

   What is pcb stand for?What is its classification?According to the circuit level classification: it is divided into a single panel, double plate and multilayer board. Common multilayer board is generally 4 or 6, the complex multilayer board up to dozens of layers.

PCB board has the following three main types of division:single sided board,dual platen,multilayer board.

   What is pcb stand for?What are the characteristics of it?PCB has been more and more widely used, because it has many unique advantages, are summarized as follows:High density, high reliability, design, production, testability, maintainability, maintainability, etc..

   What is pcb stand for?What would be the developing trend ?Discussion on the developing trend of future production and manufacture technology of printed board,which is consistent with the domestic and foreign.It develops in the following directions:high density, high precision, pore diameter, thin wire, fine pitch, high reliability, multilayer, high-speed transmission, light weight, thin and so on.In the production, at the same time, to improve productivity, reduce costs, reduce pollution, to adapt to the development of many varieties, small batch production. Printed circuit technology development level, in general to the line width of the printed board, aperture, thickness / aperture ratio of the representative.

   Production flow:

Materials -- the inner -- laminated, drilling, copper deposition - line - diagram - etching -- resistance welding - character - sprayed tin (or immersion gold) - edge of the gong - V cut (PCB parts do not need) -- flight test ---- vacuum packaging.
