PCB is a printed circuit board, also known as a printed circuit board, which is the carrying part of the electronic original.

1. The PCB board is a printed circuit board, also known as a printed circuit board, which is a provider of electrical connections for electronic components. The circuit is used as a tool for conduction between the originals. In the design, a large copper surface will be additionally designed as a grounding and power layer. The route and the drawing are made at the same time. The wiring density is high, the volume is small, and the weight is light, which is conducive to the miniaturization of electronic equipment.

2. The substrate of the board itself is made of materials that are insulated and not easy to bend. The small circuit material that can be seen on the surface is copper foil. The copper foil was originally covered on the entire board, but part of it was etched away during the manufacturing process, and the remaining part became a network of small lines. .

3. PCBs vary according to their substrate materials. High-frequency microwave boards, metal substrates, aluminum substrates, iron substrates, copper substrates, double-sided and multilayer PCBs are the abbreviations of Printed Circuit Board in English, and the Chinese name is Printed Circuit Board. Boards, also known as printed circuit boards and printed circuit boards, are important electronic components.
