Description
technical field [0001] The invention belongs to the technical field of testing and aging of driving boards, and in particular relates to a device for testing and aging of driving circuit boards of PCR instruments. Background technique [0002] At present, the commonly used aging method for driving circuit boards in the PCR field is: after commissioning and testing, perform off-line high and low temperature impact aging on the single board, and then conduct retesting to select unqualified boards. Such a process does not carry out fatigue period tests on the components in the board, nor can it pick out unstable single boards during operation, and the operation process is too cumbersome. The human factor in debugging the testing process is too large. Contents of the invention [0003] The object of the present invention is to provide a device for testing aging of a driving circuit board of a PCR instrument. [0004] The present invention includes a main board power supply, ...
