High reliability ceramic capacitor (II)

How to improve the reliability of ceramic capacitors?

No one is perfect, the device is the same, it is impossible to have only advantages, no shortcomings. Ceramic capacitors are simple because of their raw materials - soil. It is everywhere, and it is easy to take, so it has been promoted on a large scale. However, ceramics are fragile and the reliability is not high, which has always plagued people.

So how can people solve this problem and let ceramic capacitors be mass-produced? The following is a solution for a capacitor solution provided by Shanghai Runxin Technology Partner. It is also the first ceramic capacitor solution in the world to solve this problem and achieve mass production.

As we have already said before, the ceramic capacitor has an external electrode, and the external electrode includes the innermost Cu layer, the middle Ni layer and the outermost Sn layer. In order to make the capacitor's anti-bending property better, avoid between the body and the electrode. Hard tough, this scheme first proposed to add Soft Term between the Cu and Ni layers, which seems to be very simple, but it is not. It is often said in the industry that the ceramic capacitors are finally put to the study of materials, and the small material formulation differences have a great impact on the performance of the products. This program has also made countless attempts in the process of technical realization, and finally found a more suitable formula. At present, there are many manufacturers of flexible high-reliability ceramic capacitors on the market, but the principles are similar.
