1. The origin of PCB
What is PCB? Printed circuit board (PCB) was born in the first half of the 20th century. Since its invention, PCB has continuously made breakthroughs in technology. The advancement and wide PCB board application technology have led to the rapid development of semiconductor packaging technology. Thanks to this, ordinary users can use increasingly compact and efficient electronic products.
2. The definition of PCB
PCB is the basic building block of most modern electronic devices. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. During custom PCB manufacturer electronic printing, it it is given the name printed circuit board.
3. The composition of PCB
PCB is composed of multiple electronic components, which mainly include semiconductors, connectors, resistors, diodes, capacitors, and radio equipment. These electronic components are mounted on the PCB and communicate with each other through the PCB.
4. The characteristics of PCB
PCBs have mechanical and electrical characteristics. Most of the PCBs produced in the world are rigid, and only a few are flexible. These flexible PCBs can be bent and folded, or withstand hundreds of thousands of flexible cycles, without the circuit being interrupted. These flexible PCBs account for about 10% of the market share. Among them, there is a small part called rigid flex circuit boards. Part of this circuit board is rigid, which is very suitable for installing and connecting components, and the other part of it is flexible, which in turn provides users with the advantages of flexible circuits.
