PCB introduction

Printed circuit boards, also known as printed circuit boards, printed circuit boards, referred to as construction and circuit boards, often use the English abbreviation (PCBPrinted circuit board) or write PWB (Printed wire board), with the insulation board as the substrate, cut into a certain size At least one conductive pattern is attached thereto, and holes (such as component holes, fastening holes, metallized holes, etc.) are provided to replace the chassis of the electronic component of the prior device, and the interconnection between the electronic components is realized. . Since this board is made by electronic printing, it is called a "printing" circuit board.

    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 end 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 a printed circuit board refers to a bare board - that is, a circuit board without components.
