Measurement method of corrosiveness of electronic and electrical appliance service environment

Abstract

The invention discloses a measurement method of the corrosiveness of an electronic and electrical appliance service environment. The measurement method comprises the following steps: placing a copper test piece into the measured electronic and electrical appliance service environment, reducing a corrosive product film on the surface of the copper test piece through a cathode reducing method, then calculating the average thickness TCuO2 of a Cu2O corrosion product, the average thickness TCuO of a CuO corrosion product and the average thickness TCu2S of a Cu2S corrosion product, and finally calculating the total thickness average value Te, serving as a measurement result, of a surface corrosion product to acquire the corrosiveness of the measured electronic and electrical appliance service environment. Therefore, the measurement method can accurately measure the weak corrosiveness of the electronic and electrical appliance service environment under a condition of not affecting the electronic and electrical appliance service environment, so that the problem of low measurement precision caused by the adoption of a copper hanging piece weight loss method for calculating the corrosion rate in the prior art is solved.

Description

technical field [0001] The invention relates to a method for measuring the corrosivity of the service environment of electronic appliances. Background technique [0002] With the advent of the era of information and automation, large-scale precision electronic and electrical systems are gradually applied to daily life and production, such as the server system center of the network, the news media director room, the control center of the production workshop, and the experimental equipment system of the laboratory. Precision electronic appliances mostly use high-purity copper as the conductive material. The corrosion of copper will affect its conductivity, resulting in damage or failure of electronic components. This not only affects the working efficiency of electrical equipment, but also is difficult to troubleshoot and high maintenance costs. [0003] In view of the above situation, how to effectively measure the corrosiveness of the service environment of electronic applia...

AI Technical Summary

Problems solved by technology

The corrosiveness of the service environment of electronic appliances is relatively weak, and the corrosion product film is between a few nanometers and hundreds of nanometers. The traditional copper hanging piece weight loss method is often used to calculate the corrosion rate. The corrosivity of the
