Advantages of multilayer circuit boards

Information

The circuit board determines the process difficulty and processing price according to the number of wiring surfaces. Common circuit boards are divided into single panel and double panel. However, high-end electronic products are limited by product space design factors. In addition to surface wiring, multilayer circuits can also be superimposed inside. In the production process, after a layer of wiring is completed, it is positioned and pressed by optical equipment so that the multilayer circuit is superimposed on a circuit board, commonly known as a multilayer circuit board.

Multilayer circuit boards are currently the most widely used type of circuit boards in daily life. Has the following advantages:

1. High assembly density, small size and light weight;

2. Due to the high assembly density, the wiring between the components is reduced, the installation is simple, and the reliability is high;

3. Due to the repeatability and consistency of graphics, wiring and assembly errors are reduced, and equipment maintenance, debugging and inspection time are saved;

4. The number of wiring layers can be increased, thereby increasing design flexibility;

5. A circuit with a certain impedance can be formed, and a high-speed transmission circuit can be formed;

6. Circuit, magnetic circuit shielding layer can be set, and metal core heat dissipation layer can also be set to meet the needs of special functions such as shielding and heat dissipation.

With the continuous development of electronic technology, the computer, medical, aviation and other industries have continuously improved the requirements for electronic equipment. The circuit board is developing in the direction of reducing the size, reducing the quality and increasing the density. Due to the limitation of available space, single and double panels cannot further increase the assembly density, so it is necessary to consider the use of multilayer circuit boards with more layers and higher assembly density. Multilayer circuit boards have been widely used in the manufacture of electronic products because of their flexible design, stable and reliable electrical performance, and superior economic performance.

The evaluation system of the circuit board factory should follow the following principles

The evaluation system of the circuit board factory should follow the following principles

Establishing a good cooperative relationship with circuit board factories is conducive to cost reduction, response time reduction and the creation of new market value, etc. The core issue is how to choose the ideal circuit board factory. There are many factors involved in the evaluation of circuit board factories, and the evaluation index systems are diverse, both qualitative and quantitative, and the index weights are also different. Therefore, it is necessary to establish a universal and expandable evaluation index system for circuit board factories. , And the indicator system should follow the following principles:
The use of soft and hard circuit boards?

The use of soft and hard circuit boards?

In our daily life, circuit boards are mostly single-sided, double-sided, or multi-layer boards, rigid boards, metal-based circuit boards, aluminum, copper substrates, thermally conductive fiberboards, etc., do you know what a flexible and rigid circuit board is? Rigid-flex circuit board: refers to a special circuit board made by pressing a rigid circuit board (PCB) and a flexible circuit board (FPC). The main board materials used are rigid board FR4 and flexible board polyimide (PI). Rigid and flexible circuit boards combine the rigid characteristics of rigid circuit boards and the advantages of flexible circuit
Soft and hard circuit board production process

Soft and hard circuit board production process

The flexible and hard circuit board is the flexible circuit board and the rigid circuit board. After pressing and other processes, they are combined according to the relevant process requirements to form a circuit board with FPC characteristics and PCB characteristics. In the past, two hard boards were connected by using soft boards and connectors to connect each other. In order to improve the reliability of the connection between the rigid board and the flexible board, the flexible board is directly fabricated between two rigid boards in the printed circuit board (PCB) factory, which can avoid the subsequent connection process, whether it is a rigid board manufacturer or FPC manufacturers are now able to supply rigid-flex boards. Under the demand for light and thin end products, the
