Abstract

The invention discloses an electronic circuit product chip scale maintenance intelligent detection card which comprises a power supply, an input port, a both-way port, a communication interface unit and a control unit. The input port collects level signals and identity (ID) information of a detecting object and sends the level signals and the ID information to the control unit; the both-way port collects frequency signals and analog quantity signals of the detecting object, sends the frequency signals and the analog quantity signals to the control unit and sends driving signals to the detecting object according to commands of the control unit; the communication interface unit is connected with the control unit and an external personal computer (PC); and the control unit receives information collected by the input port and the both-way port, processes the information into recognizable information of the PC, sends the information to the external PC through the communication interface unit, simultaneously receives control commands sent by the external PC and sends driving commands for driving the detecting object to the both-way port. The electronic circuit product chip scale maintenance intelligent detection card has generality and intelligent detection methods.

Description

technical field [0001] The invention relates to a device for chip-level maintenance of electronic circuit products, in particular to a general-purpose intelligent detection card for chip-level maintenance of electronic circuit products. Background technique [0002] The maintenance of electronic circuit products requires the help of special tools, especially in some occasions where chip-level maintenance is required, such as computer motherboards, it is often necessary to use specially designed test cards to complete the maintenance work. This detection card has an interface circuit that matches the circuit board to be tested, and is used in maintenance with special fault detection software. A test card dedicated to computer motherboards has an interface expansion circuit corresponding to a specific slot on the motherboard, which can be plugged into the motherboard, and then read the test results of the self-test program in the BIOS and display them through codes. Code defi...
