Method capable of preventing getter dropping particles as well as getter and reinforcing coating assembly

Abstract

The invention discloses a method capable of preventing getter dropping particles. The method comprises the following steps: S1 of spraying a reinforcing coating at a joint of the end surface of the powder and a conductor, wherein the conductor penetrates through the powder; and S2 of curing the sprayed reinforcing layer. According to the method disclosed by the invention, the reinforcing coating is sprayed to the joint of the end surface of the powder and the conductor, and the sprayed reinforcing coating is cured, so that the end surface of the powder is reinforced, and therefore, particles are prevented from dropping from the joint of the end surface of the powder and the conductor. Besides, the reinforcing coating is further sprayed to residual powder left on the conductor to further prevent dropping particles. The reinforcing coating can be specifically protective glue, nano sliver paste or a metal coating with low gas release amount. The invention further discloses a getter and areinforcing coating assembly.

Description

technical field [0001] The present invention relates to the field of getters, and more particularly, to a method of preventing getters from falling particles and a getter and reinforcement coating assembly. Background technique [0002] Getters are widely used in vacuum electronic devices to eliminate the residual gas in the package and the re-released gas during aging, and provide a good vacuum working environment for electronic devices. Non-evaporable getters are one type of getters. The non-evaporable getter is made of a getter material with a high evaporation temperature, which can be activated by proper heat treatment to meet the getter performance. [0003] as attached figure 1 And attached figure 2 shown, with figure 1 The front view of the getter provided for a specific embodiment of the prior art, figure 2 for figure 1 The side view of , wherein 10 is a powder, 20 is a conductor. [0004] However, non-evaporable getters will shed particles during the activa...

Problems solved by technology

However, as the sintering strength increases, the brittleness of the getter material itself will increase, and the part of the getter end face that is in contact with the conductor will more easily shed particles when subjected to high-level shocks and vibrations
