PCB manufacturing: ceramic circuit board

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.

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 degree Celsius. 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.
