What Are The Types Of Printed Circuit Boards?

What are the types of printed circuit boards? What industry does printed circuit board belong to?

For the production of printed boards, because many designers do not understand the production process of circuit boards, the circuit diagrams they design are only the most basic circuit diagrams and cannot be directly used for production. Therefore, it is necessary to modify and edit the circuit file before actual production, not only to produce a film suitable for the production process of our factory, but also to produce corresponding punching data, mold opening data, and useful information for production. other data. It is directly related to the various production projects in the future. The following editor will introduce to you "what industry does the printed and what are the types of printed circuit boards?"

1. What industry does the printed circuit board belong to?

Circuit board manufacturing belongs to the modern electronics industry. Circuit board is also called: PCB board, aluminum substrate, high frequency board, PCB circuit board , PCB, circuit board, printed circuit board, Shenzhen circuit board, Shenzhen circuit board, flexible board, flexible board and so on. The circuit board is also called: PCB board, aluminum substrate, high frequency board, PCB circuit board, PCB, circuit board, printed circuit board, Shenzhen circuit board, Shenzhen circuit board, flexible board, flexible board and so on.

2. What are the types of printed circuit boards?

1. Single-sided printed circuit board

A single-sided printed circuit board is coated with copper foil on one surface of an insulating substrate with a thickness of 0.2~0.5mm, and a printed circuit is formed on the substrate by printing or etching. It is suitable for electronic products with low density of electronic components, such as radios, doorbells, desk lamps and other general electronic products, and is more suitable for handmade.

2. Double-sided printed circuit board

The double-sided printed circuit board is coated with copper foil on both surfaces of the insulating substrate with a thickness of 0.2~0.5mm, and printed circuits can be made on both sides. It is suitable for electronic products with relatively high density of electronic components, such as televisions, oscilloscopes, MP4 and other electronic products with complex circuits. Due to the high wiring density of double-sided printed circuits, the volume of electronic products can be reduced, which requires a special manufacturing process, and general manual production is not easy to meet the requirements.

3. Multilayer printed circuit board

A printed circuit board made of more than three layers of printed circuits on an insulating substrate is called a multilayer printed circuit board. It is made of several layers of thinner single-panel or double-layer panels, and its thickness is generally 1.2~2.5mm. In order to design and manufacture the circuit sandwiched in the middle of the insulating substrate out of the printed circuit board , the holes for installing components on the multilayer printed circuit board need to be metallized, that is, the inner surface of the small hole is coated with a metal layer to make it different from that sandwiched in the insulating The printed circuit in the middle of the substrate is connected. Its characteristic is that it is designed and manufactured by using printed circuit boards in conjunction with integrated circuit blocks , which can reduce the volume and weight of the product, and can also add a shielding layer to improve the electrical performance of the circuit.

4. Soft printed circuit board

The base material of the flexible printed circuit board is soft layered plastic or other soft modulus materials, such as polyester or polyimide insulating material, and its thickness is between 0.25 and 1mm. It also has single-layer, double-layer and multi-layer points. It can be terminated and connected to any specified position, such as the electrical connection between the clamshell and the body of the mobile phone. It is widely used in electronic computers, communications and instruments, etc. on electronic products.

5. Flat printed circuit board

Embed the printed wires of the printed circuit board into the insulating substrate so that the wires are flush with the surface of the substrate to form a flat printed circuit board. A wear-resistant metal layer is plated on the wires of the flat printed circuit board, which is often used in transfer switches, computer keyboards and other equipment.
