1. Description of the data in the table: The operation time of each electronic unit in the remanufacturing process (the mainboard detection time is measured in hours; the repair time of the power supply, fan, mainboard, and hard disk is measured in minutes; the detection time of hard disk and memory is measured in minutes; and other time units are measured in seconds).

2. Data function: used to evaluate technical difficulty.

3. How to obtain: stopwatch timing.
