Problems solved by technology

However, the formation of the two opposite electrodes needs to involve photolithography and etching technology, and the production cost is high, and the length and width of the narrow gap between the electrodes are limited to a certain extent, which may easily cause the trigger voltage of the product to be too high and the dispersion is large, and the narrow Excessive current density between the gaps will also cause the electrode end face to be ablated

Description

technical field [0001] The invention relates to an electrostatic suppression element and a manufacturing method of the element, in particular to an electrostatic suppression element and method manufactured by using LTCC ceramic matrix stacking technology and pressure-sensitive ceramic material as a functional phase. Background technique [0002] All substances in nature are composed of atoms. Protons (positive charges) and electrons (negative charges) in atoms exist in every corner of our lives. Whenever two different materials come into contact with each other and separate, The so-called "triboelectric" effect occurs, and the subsequent transfer of charge to an object with a lower potential is called "electrostatic discharge (ESD)". It is difficult to completely eliminate static electricity in the process of static electricity protection, but we can take protective measures to minimize the generation and accumulation of static electricity, so the important issues facing des...
