Shell testing method

Abstract

An embodiment of the invention provides a shell testing method. The shell testing method comprises the following steps that a to-be-tested shell is provided; at least one screening test is carried outon the to-be-tested shell, wherein at least one screening test comprises a baking test so as to test whether the to-be-tested shell meets the preset shell performance requirement or not; and if the to-be-tested shell meets the preset shell performance requirement, preprocessing is carried out on the to-be-tested shell to obtain a preprocessed shell, and at least one environment reliability test is carried out on the preprocessed shell, wherein at least one environment reliability test is used for testing whether the performance of the preprocessed shell meets the preset reliability requirement or not. According to the method, the to-be-tested shell is subjected to screening test firstly to test whether the to-be-tested shell meets the preset shell performance requirement or not, so that whether the manufacturing process of the to-be-tested shell is qualified or not can be preliminarily judged, the potential cracking defect of the to-be-tested shell is improved in advance, the problemof cracking of the to-be-tested shell in the environment reliability test is avoided, and the number of times of repeated testing is reduced.

Description

technical field [0001] The present application relates to the technical field of electronic equipment testing, in particular to a testing method for a housing. Background technique [0002] At present, various electronic devices need to use casings to carry or accommodate other functional devices. Usually, the casing needs to undergo a series of environmental reliability tests before leaving the factory to verify the reliability of the casing in an extreme temperature environment. Usually some of the casings to be tested are of poor quality, and cracking problems are prone to occur during the environmental reliability test, resulting in the scrapping of all the test casings in this batch. It is necessary to change the process to make a new batch of casings, and then conduct the environmental reliability test. The test method of the casing has low test efficiency and delays the production progress of the product. Contents of the invention [0003] An embodiment of the pre...
