What are the abnormal quality of circuit board development?
A multilayer board is a printed circuit board with three or more layers of conductive pattern layer and insulating material between them, and the conductive patterns are interconnected. Multilayer PCB is a product of high speed, multi-function, large capacity, small volume, thin and lightweight. According to the characteristics of the circuit board if divide into soft board (FPC), and (PCB), flex board (FPCB).
Double panel is an extension of a single panel, when the single layer wiring can not meet the needs of electronic products, it is necessary to use a double-sided board. Both sides of the copper covered with a line, and through the hole to pass through the two layers of the line, so that the formation of the required network connection.
The first is a single panel, in the most basic PCB, the parts are concentrated in one side, the conductor is concentrated on the other side. Because the wire only appears on one side, it is called the PCB. Single panel is usually simple, low cost, but the drawback is that it can not be applied to complex products.
Circuit board divided by the number of layers is divided into single panel, double-sided board, and multilayer circuit board three major categories.
