The structure of the circuit board

With the development of science and technology, the circuit board is an active industry in the contemporary electronic component industry. Under the circuit board, follow the Jingchuangda circuit board manufacturer to understand the circuit board structure.

The circuit board structure is mainly composed of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. The main functions of each component are as follows:

Pad: A metal hole used to solder the pins of components.

Vias: There are metal vias and non-metal vias. Metal vias are used to connect component pins between layers.

Mounting hole: used to fix the circuit board.

Wire: The copper film of the electrical network used to connect the pins of the components.

Connectors: components used to connect between circuit boards.

Filling: Copper coating for ground wire network, which can effectively reduce impedance.

Electrical boundary: used to determine the size of the circuit board, all components on the circuit board cannot exceed the boundary.

The above is the structure of the circuit board. If you want to know more information about the circuit board, you can pay attention to Jingchuangda circuit board manufacturers.
