The development of ceramic circuit board industry

Information

The ceramic circuit board industry is no longer an emerging industry, but it is still a thriving "boy" for China. Now the domestic ceramic circuit board industry has entered a period of rapid development. Each industry has the idea of dividing the cake, and at the same time, it has also incorporated ideas from other fields, directly bringing changes to the entire industry. The biggest change is the channel.

As we all know, when more and more competitors begin to appear in a certain industry, we must consider to seize more markets through more channels. But this is not the case with ceramic circuit boards. The ceramic circuit board industry in the past was a purely online industry, and all transactions basically depended on offline communication, which can ensure that everyone makes a lot of money. However, the ceramic circuit board industry used to be only a "land trade" business. It was fixed in its own circle and could not contact the outside world, and the outside world could not contact them. It is almost impossible to grow bigger. Until the capital noticed this piece of cake and started to enable the network mode, the old PCB manufacturers did not wake up.
The advantages of ceramic circuit boards

1. The ceramic circuit board is loaded with heavy weight, and the 100A current continuously passes through the copper body with a thickness of 1mm and 0.3mm, and the temperature rises by about 17℃. A current of 100A is continuously passed through a copper body with a thickness of 2mm and 0.3mm, and the temperature rise is only about 5°C.

2. The ceramic circuit board has better heat dissipation performance, low thermal expansion coefficient, stable shape, and warpage is not easy to deform.

3. Good insulation, high pressure resistance, to ensure personal safety and equipment.

4. Strong bonding force, using bonding technology, the copper foil will not fall off.
Disadvantages of ceramic circuit boards

1. Fragile, this is the main shortcoming of ceramic circuit boards, so it can only be used to make small-area circuit boards.

2. The price is high, and there are more and more requirements for electronic products. Ceramic circuit boards are used for relatively high-end products, and low-end products are not used at all.

The use of ceramic circuit boards

1. Used for high-power electronic modules, solar panel modules, etc.

2. High frequency switching power supply, solid state relay

3. Automotive electronics, aerospace and military-needed electronic products

4. High-power LED lighting products

5. Communication antenna, car ignition

From the overall performance point of view, the ceramic circuit board PCB is far better than the usual FR-4 board, but it is also very high from the cost point of view! Therefore, it is wise to choose ceramic circuit boards according to the needs.

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
