Each enterprise is divided into several situations to the burin-in process of electric sub-member plate at present:
(1) is placed under the hot environment aging several hours～tens hours earlier, detects one by one more after cooling.
(2) electric sub-member plate is installed on the product device, the complete machine energising was worn out in tens hours.
(3) do not wear out, directly installation detects.
First method is used the most generally, advantage is to realize easily, but not power up, the aging detection under the high-temperature work environment, can not find the fault under the actual working environment, some device is degradation at high temperature, get back to and recover normal under the normal temperature again, potential faults fails to get rid of, and therefore this aging method is defective.Second method, ageing efficiency is low, generally should not adopt.The third method does not wear out, and can not screen the failure rate height of product to defective electric sub-member plate.
