Description

Technical Field

[0001] The present invention relates to the technical field of automated detection, and in particular to a mainboard voltage-stabilizing plug-in test tool. Background Art

[0002] Laptop motherboards integrate too many electronic components. When testing the motherboard's functions, precise measurements are required from the perspective of use, including screen display, keyboard and mouse operation, various connector plug-in tests, touchpad tests, etc. The tests on multiple connectors include mechanical plug-in performance tests and contact conductivity electrical tests.
