Abstract

The invention discloses an electronics ageing test system. The electronics ageing test system is characterized in that the test system is a backend system controlling a PLC (programmable logic controller) module to be connected with a temperature module, a moisture module, a temperature regulating module, a moisture regulating module and a time regulating module respectively. The time regulating module is connected with a product to be tested. A signal source module is connected to the product to be tested after communicated with the PLC module. According to the arrangement, the electronics ageing system has the advantages that indoor temperature and moisture setting range is wide, optional continuous adjustment is achieved within the normal temperature within 85 degrees and 0%-100% RH (Relative humidity); with complete protection functions, the system is smoothly tested in a safe and stable manner; signal inputting and timing are performed according to the product performance, thus the on-line test of the electronics is accurate; reliability of the electronics is greatly improved.

Description

technical field [0001] The invention relates to the field of quality detection of electronic products, in particular to an electronic product aging test system. Background technique [0002] Electronic products, whether they are components, components, complete machines, or equipment, must undergo aging tests. After the electronic product has been manufactured, it has formed a complete product, which can already exert its use value, but after using it, it is found that there will be various problems, and it is found that most of these problems occur within a few hours to dozens of hours at the beginning. Later, it was simply stipulated that electronic products must pass an aging test before being put into the market. [0003] In order to achieve a satisfactory pass rate, almost all electronic products have to undergo aging tests before leaving the factory. The aging test of electronic products refers to testing the electronic products before leaving the factory according t...
