Ceramic circuit board is a new type of circuit board with ceramics as the substrate and a variety of different circuit components attached to the outside. It is widely used in the manufacturing of the electronics industry. It has many advantages due to its good thermal conductivity, high pressure resistance, and stable chemical properties. Become an important part of electronic product manufacturing. With the increasing number of ceramic circuit board products, how to distinguish a high-quality ceramic circuit board from many manufacturers and brands requires certain skills.
1. Look at the material of the ceramic plate. Since the ceramic PCB circuit board uses the ceramic substrate as the support board of its circuit, the quality of its material has a very important influence on the performance and service life of the ceramic circuit board to a certain extent. The quality-guaranteed ceramic circuit board should be made of ceramic substrate materials with stable chemical properties (high temperature resistance, strong acid and alkali resistance), high thermal conductivity, and many good quality ceramic substrate materials.
2. See if the ceramic circuit board is finely crafted. Since ceramic circuit boards are precision circuit board components, there are countless resistance and capacitance elements on a small area ceramic board. High-quality ceramic circuit boards require strict requirements on the distance and adhesion of electronic components. Of course, ceramic circuits The high flatness of the appearance and flat edges of the board can also reflect its processing quality.
3. Pass the trial. One of the great advantages of ceramic circuit boards is their good thermal conductivity, which in turn ensures their resistance to high pressure and durability. The manufacturer can let the circuit board work for a period of time, then cut off the power supply to stop its work, test its temperature and the current flow rate of the entire circuit, if the temperature is too high, it means that its thermal conductivity is poor, and it is not a good quality ceramic circuit board.
4. Understand the information of ceramic circuit board proofing manufacturers. The manufacturer of ceramic circuit boards is formal, has a large scale, and has a variety of qualifications, which often means that its production and manufacturing are through formal and strict production processes and requirements, and the selection of materials will also be guaranteed. It shows that it is a ceramic circuit board that has passed the quality certification; of course, at the same time, we must also understand the corresponding brand reputation of the ceramic circuit board and its user evaluation. These two aspects of information can often directly show the ceramic circuit board to a certain extent. Quality situation.
In the end, the products are based on excellent products and reputation and integrity to attract and retain customers. From the raw materials themselves to the final products, every link is guaranteed to be genuine at a fair price. Manufacturers also carefully choose and consider the needs of their products to avoid risking their products. After all, win-win cooperation is the long-term way.
