PCB Technical - Rigid circuit board

Printed circuit boards can be divided into rigidprinted boards and flexible printed boards according to the materials produced. Rigid circuit boards are mainly manufactured using copper clad laminates as the base material. Rigid printed boards include phenolic paper laminates, epoxy paper laminates, polyester glass mat laminates, and epoxy glass cloth laminates. The following editor will explain in detail what is a rigid circuit board and its characteristics And role.

Rigid circuit board introduction:
Rigidity: The ability to resist deformation. Generally refers to the ability of a material to not deform under the action of external force. Circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board. The combination of these two means a circuit board that is not easily deformed.

Rigid circuit board features:
1. High density:

For more than 100 years, the high density of printed boards has been able to develop along with the improvement of integrated circuit integration and the advancement of mounting technology.

2, high reliability:

Through a series of inspections, tests and aging tests, the PCB can be guaranteed to work reliably for a long time (use period, generally 20 years).

3. Designability:

For the various performance requirements of PCB (electrical, physical, chemical, mechanical, etc.), printed board design can be realized through design standardization, standardization, etc., with short time and high efficiency.

4. Productivity:

Using modern management, standardization, scale (quantity), automation and other production can be carried out to ensure the consistency of product quality.

5. Testability:

has established relatively complete test methods, test standards, various test equipment and instruments to detect and appraise the eligibility and service life of PCB products.

Rigid circuit board function:
After electronic equipment adopts printed boards, due to the consistency of similar printed boards, manual wiring errors can be avoided, and electronic components can be automatically inserted or mounted, automatic soldering, and automatic detection, ensuring the quality of electronic equipment, Improve labor productivity, reduce costs, and facilitate maintenance.

The role of printed circuit boards
1. Printed circuit boards, also known as printed circuit boards, are the providers of connections. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is to greatly reduce wiring and assembly errors, and improve the level of automation and production labor rate. According to the number of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multilayer circuit boards. Because it is made by electronic printing, it is called a "printed" circuit board.

2. The printed circuit board is mainly composed of two types of materials: insulating base material and conductor, which play the role of support, interconnection and some circuit components in electronic equipment. Integrated circuits and electronic components such as resistors and capacitors cannot function as a single individual. Only when they have a foothold on the printed circuit board and have a conductive junction to connect them, can they perform their functions in this whole.

3. The printed circuit board is the skeleton supporting the components and the pipeline connecting the electrical signals. In addition, some printed circuit boards have components such as resistors, capacitors, and inductors attached to them, which become functional circuits and act as devices.

4. The role of the printed circuit board in the electronic equipment is: to provide fixed and assembled mechanical support for transistors, integrated circuits, resistors, capacitors, inductors and other components; to realize transistors, integrated circuits, resistors, capacitors, inductors, etc. The wiring and electrical connection and electrical insulation between components are used to meet their electrical characteristics; it provides identification characters and graphics for the inspection and maintenance of components in the electronic assembly process, and provides solder mask graphics for wave soldering.

5. Because the printed circuit board is used in the electronic equipment, manual wiring errors are avoided, and automatic insertion, welding and detection are realized. This ensures the quality and reliability of the electronic product, improves labor productivity, reduces production costs, and facilitates maintenance.
