When buying piezoelectric ceramic pieces, we need to understand through the following ways:

?? First look at surface roughness.

The surface roughness is a very key part to judge the quality of ?? piezoelectric ceramic plate. If the surface roughness is relatively large and the dimension accuracy of ?? is not high, such piezoelectric ceramic plate is certainly not good from the comprehensive effect.

?? Second look at the ?? parameter of the piezoelectric ceramic plate.

?? The parameters of the piezoelectric ceramic plate are also very important, such as the relevant parameters of some materials of the piezoelectric ceramic plate, etc., these are very important.

?? The third is to learn to see the ?? process of piezoelectric ceramic pieces.

? ? piezoelectric ceramic chip process is very complex, ? ? have mixed - shape processing and so on, for example, the process is more complex, so in the piezoelectric ceramic piece after also need to undertake high pressure plans and aging test, ? ? did aging test of piezoelectric ceramic piece ? ? is certainly not high quality, ? ? so on this issue, We must pay attention to ?? to find the right way, because sometimes if you can't find the right way, there is no way to buy the right piezoelectric ceramic products.

Fourth: look for professional personnel to check piezoelectric ceramic piece

Quality of piezoelectric ceramic piece we ? ? inspection process, but also to find the professional and technical personnel, accompanied by ? ? buyers in the process of purchasing of piezoelectric ceramic piece, it's easy to own ? ? into some detours, because their for piezoelectric ceramic pieces of technology do not understand, make oneself buy piezoelectric ceramic chip quality is not high, Therefore, we also need to find professionals to accompany ?? procurement personnel to purchase together, ?? procurement personnel know more about the details of procurement, and professionals know how to judge the quality of a piezoelectric ceramic plate, ?. Therefore, it is better for procurement staff of purchaser to complete the procurement of piezoelectric ceramic plate together with professionals.
