Electronic Printed Circuit Board

Electronic Printed Circuit Board

The Electronic Printed Circuit Board is an electronic circuit used in electronic devices to provide mechanical support and access to its electronic components. It is made by combining different sheets of non-conductive material, such as fiberglass or plastic, to easily hold the copper circuit.

According to the number of circuit boards, it can be divided into single-panel, double-panel, four-layer, six-layer and other multi-layer boards.

Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. For example, the motherboard for the personal computer is called the motherboard, and cannot be directly called the circuit board. Although there is a circuit board in the motherboard, It's not the same, so when you evaluate the industry, you can't say the same thing. For example, because the integrated circuit parts are mounted on the circuit board, the news media called him an IC board, but in essence he is not equivalent to a printed circuit board. We usually say that the printed circuit board refers to the bare board - that is, the board without the upper components.
