Glass ceramic body static inhibitor and preparation method thereof

Abstract

The invention provides a glass ceramic body static inhibitor and a preparation method thereof. The static inhibitor comprises a glass ceramic substrate, a pair of inner-side electrodes and a pair of outer-side electrodes, wherein the inner-side electrodes and the outer-side electrodes are respectively positioned on the inner and outer sides of the glass ceramic substrate. The static inhibitor further comprises a cavity structure arranged inside the glass ceramic substrate. Through filling an organic filler, the sintering temperature and the sintering atmosphere during the manufacturing process of the glass ceramic substrate can be controlled, so that the glass ceramic substrate is formed through the splitting decomposition of the organic filler. Meanwhile, the interior of the glass ceramic substrate contains at least one part of gases generated during the splitting decomposition process of the organic filler. The pair of inner-side electrodes is positioned in the same horizontal plane. The outer end portions of the inner-side electrodes are respectively connected with the pair of outer-side electrodes at the two ends of the glass ceramic substrate. Meanwhile, the two inner-side electrodes are arranged at a preset interval to form a capacitor structure. At least the capacitor structure is enclosed inside the cavity structure. The preparation method is used for preparing the above static inhibitor. The static inhibitor is long in life cycle and is not easily invalid even after being used for a long period of time. Meanwhile, the short-circuit risk does not easily occur, and the triggering voltage is relatively low.

[0002] With the development of communication technology, the transmission rate of communication equipment is increasing day by day. In order to prevent the attenuation and distortion of the signal during high-speed signal transmission caused by capacitance, a large number of polymer electrostatic suppressors, polymer electrostatic suppressors and other products have emerged in large numbers. The ESD (Electro-Static discharge, electrostatic discharge) protection on the high-speed transmission signal line has a certain effect, but this series of products are prone to failure during long-term use. Most of the failure modes are short circuits caused by the failure of internal functional materials, and due to Functional materials always contain a certain amount of organic matter, which leads to a high initial trigger voltage of the product and a large span of electrical properties

However, in the IC module, the electrostatic peak is small and the energy is low, so that this kind of product cannot be triggered when it is used in the IC module, and it is impossible to control the clamping voltage within the allowable error range of the IC module.
