PC00459G CM210901

Wire: The electrical network copper film that connects the pins of a component.

Connector: A component that connects circuit boards.

Filling: The grounding network of copper, can effectively reduce the impedance.

Electrical boundary: Determine the size of the circuit board. All components on the circuit board cannot exceed this boundary.

Circuit board classification:

According to the number of layers, circuit boards are divided into single panel, double panel, and multilayer circuit boards. A single panel, on the most basic PCB, has parts on one side and wires on the other. This type of PCB is called a single-sided circuit board because the wires appear on only one side. Dual panel is an extension of single panel, when single-layer wiring cannot meet the needs of electronic products, dual panel may be needed. Both sides are covered with copper and have a route, and the line between the two layers can be guided through the hole, so that it forms the required network connection. The multilayer board refers to a printed board having more than three layers of conductive graphics layers and insulating materials between them, and the conductive graphics between them are interconnected according to requirements. Multilayer circuit board is electronic information technology to high speed, multi-function, large capacity, small volume, thin, lightweight direction of development products.
