Abstract

The invention discloses a safe and efficient keyboard motherboard function test device which comprises a keyboard motherboard clamping fixture, a control board, a keyboard signal line, a keyboard test key board, and a desktop computer. The keyboard motherboard clamping fixture comprises a base, a test base plate, an insulating pressure plate, and a pressing handle. The test base plate is installed on the base. The control board is arranged in the accommodating cavity of the base. The test base plate is provided with a limit groove for placing a motherboard. The limit groove is internally provided with a telescopic probe corresponding to the keyboard motherboard. The insulating pressure plate is provided with insulating fixed pins. The insulating pressure plate and the test base plate are correspondingly arranged up and down. The pressing handle is connected with the insulating pressure plate. The keyboard test key board is provided with a keyboard motherboard connection jack and a keyboard signal output interface. Simulated and actual keyboard test is carried out through the keyboard motherboard, the keyboard test key board and the desktop computer. The problem that a notebook computer is directly burned out by over-voltage and over-current in actual test of the keyboard of the notebook computer is prevented. The input of material and financial resources is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit board testing, in particular to a keyboard main board function testing device. Background technique [0002] After the notebook keyboard circuit board is assembled and processed, it is necessary to carry out a simulated keyboard test on the circuit board before leaving the factory to ensure the quality of the delivered circuit board. When testing the notebook keyboard, the circuit board needs to be loaded into the notebook keyboard. Test each key of the keyboard to complete the test of the keyboard, and check whether the function of each key is in normal use. The test principle of this test method is: use the keyboard circuit board to be tested to replace the keyboard circuit board of the notebook itself, and then press the keys on the keyboard circuit board to be tested one by one to perform keyboard testing, and the notebook is used to test the keyboard keys result. [0003] Due to the mass pr...
