The reason why the production of multi-layer circuit boards does not pass

Information

1. The quality of the circuit board raw materials does not meet the standards.

The quality of the raw material is the guarantee of the basic quality of the multilayer circuit board. If the quality of the raw material of the circuit board is not good, the produced circuit board will have bubbles, board warpage and uneven thickness.

2. The circuit board production process is unqualified.

Each process in the production process must be strictly implemented in the production process, and each process must be equipped with corresponding test equipment to ensure the stable quality of the multilayer circuit board. Because many circuit board factories do not meet the standards in production technology, the circuit boards they produce are sold at lower prices. If such circuit boards are put into use, various problems are prone to occur.

3. The circuit board production equipment does not meet the standard.

With the development of science and technology, the multi-layer circuit board production equipment is being updated faster and faster, and the price is getting more and more expensive. The fundamental way to improve the quality of circuit boards is to ensure the quality of the equipment from the hardware, increase equipment investment, and make the equipment run stably. Therefore, some small circuit board factories cannot purchase expensive equipment, resulting in the production of multilayer circuit boards that do not meet the production requirements.

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
