Background

The electronic ceramic is widely used for manufacturing electronic functional elements, and is essentially different from common electric power ceramic in chemical components, microstructures and electromechanical properties. These differences are due to a series of special technical requirements imposed on electronic ceramics by the electronics industry, the most important of which is to have high mechanical strength, high temperature and humidity resistance, radiation resistance, wide variation of dielectric constant, small dielectric loss tangent and adjustable temperature coefficient of capacitance. High electric strength and insulation resistance, excellent aging resistance and the like.

Electronic ceramics can be widely applied to the aspects of energy, household appliances, automobiles and the like, but due to the light and thin property, the electronic ceramics are easy to crack when drilling, in the traditional drilling process, because a clamp can only cover the local part of the ceramics, the vibration force applied to the ceramics can only be borne by a region contacted with the clamp, so that the vibration force applied to the whole ceramics can not be uniformly distributed, and the light and thin ceramics are easy to crack, so that the traditional clamp equipment can not meet the drilling operation of the light and thin ceramics.
