PCB circuit board (printed circuit board), also known as printed circuit board, printed circuit board, referred to as printed board, English referred to as PCB (printed circuit board) or PWB (printed wiring board), with insulating board as the base material, cut into A certain size, with at least one conductive pattern on it, and holes (such as component holes, fastening holes, metallized holes, etc.), used to replace the chassis of the electronic components installed in the past, and to realize the connection between electronic components interconnected. Since this board is made by electronic printing, it is called "printed circuit board". It is not accurate to call "printed circuit board" as "printed circuit" because there are no "printed components" on the printed board but only wiring.
It is an important electronic component and a support for electronic components.
Printed circuit boards are not general end products, and the definition of the name is slightly confusing.
For example, motherboards for personal computers are called motherboards, but not circuit boards. Although there are circuit boards in motherboards, they are not the same. Therefore, when evaluating the industry, the two are related but cannot be said to be the same.
Another example: because there are integrated circuit parts loaded on the circuit board, the news media call it an IC board, but in fact it is not equivalent to a printed circuit board. The printed circuit board we usually refer to refers to a bare board—that is, a circuit board without components.
Classification according to the number of PCB circuit layers: PCB printed circuit boards are divided into single-panel, double-panel and multi-layer boards. Common multi-layer boards are generally 4-layer boards or 6-layer boards, and complex multi-layer boards can reach dozens of layers.
