Abstract: The aging test is to eliminate the damaged components in the element screening test on the premise of following the principle of the "bathtub curve", so as to improve the overall reliability of the components. The article mainly studies how to use the same aging test printed circuit board for chips of the same package size. It is not necessary to make different aging test printed circuit boards due to their different functions , thereby reducing manual and hardware costs and improving efficiency. Through the research of chips and aging test printed circuit boards , corresponding mother boards and daughter boards were designed. The design of universal aging test printed circuit boards was successfully completed. Based on this, the design was expanded, involving more than 30 types of chips of different sizes. There are hundreds of types of cover chips.

Key words: aging test, universal printed circuit board, mother board, daughter board
