What is the use of circuit boards?
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.
The circuit board makes the circuit miniaturization and intuitive, and plays an important role in the mass production and optimization of the electrical layout of the fixed circuit.
Printed circuit board or printed circuit board
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.
