PCB is a printed circuit board, also known as a printed circuit board, which is the carrying part of the electronic originals.
1. The PCB is divided into single-layer, double-layer and multi-layer, and together with electronic components, it forms a unit circuit to complete certain preset functions and purposes.
2. Process control block (PCB) (a special data structure set by the system to manage the process, it is used to record the external characteristics of the process and describe the movement change process of the process. The system uses the PCB to control and manage the process, so the PCB is the system The only sign to perceive the existence of the process. The process and the PCB are in one-to-one correspondence.
3. How advanced a country's semiconductor technology is often reflects how high the country's modern industrial level is. The electrical interconnection and assembly of semiconductors must be based on circuit boards. Printed circuit boards are used in almost all electronic products such as communication equipment and computers. The English full name of the printed circuit board is Printed Circuit Board, abbreviated as PCB.
