Improved methods and apparatus is disclosed for electrical testing of electronic circuits such as those existing in microcircuit devices including chip carriers, printed circuit boards and substrates. The invention provides for the testing of the continuity of electronic circuits in progressively smaller devices having increased density of circuits and having pads closely spaced. A quasi-fluidized bed of conductive particles is provided for effectively contacting pads on a first side of a substrate. Pads on another side of the substrate which are connected to the pads on the first side are then contacted by a test device. The circuit interconnecting respective pads on the two sides of the substrate can then be assessed for electrical continuity.

The invention relates to a circuit and a method for measuring battery electric quantity. The circuit comprises a sensing resistor, a voltage and current converting circuit, a subtractor, a comparer, a logic circuit and a power supply management unit, wherein a first conversion circuit of the voltage and current converting circuit obtains a first voltage signal according to one end of two ends of the sensing resistor and converts the first voltage signal into a first current signal; a second conversion circuit of the voltage and current converting circuit obtains a second voltage signal according to the other end of two ends of the sensing resistor and converts the second voltage signal into a second current signal; the subtractor provides a current difference signal according to the firstcurrent signal and the second current signal; the comparer outputs a comparison signal according to the current difference signal and the current dead band; the logic circuit outputs a logic signal according to the comparison signal and a preset signal; and the management unit calculates the battery electric quantity according to the logic signal.

The invention discloses a testing method and a system for testing personnel of a display panel. In the testing method of the display panel inspector, after the inspector judges the standard images displayed on several panels, a simulated defect information is displayed to the inspector, and the identification result of the inspector is compared with the simulated defect information , to identify the correctness of the judgment made by the inspector. The present invention displays the virtual defect information to the inspectors to monitor the judgment of the inspectors by using the system, and monitor the accuracy of the judgment of the inspectors in real time, thereby improving the accuracy of the inspection and reducing customer complaints.

The invention provides a method for manufacturing an FPC, which includes: providing an FPC small board, and at least one FPC single piece is arranged on the FPC small board; performing a first punching shape treatment on the FPC small board; and cleaning the FPC small board ; Provide a supporting substrate, set the FPC small plate on the supporting substrate; carry out the second punching shape processing on the supporting substrate and the FPC small plate on it; inspect the FPC single piece on the supporting substrate; The support substrate is peeled off to obtain a single piece of FPC. Compared with the prior art, the present invention disposes the FPC small board on the supporting substrate before performing the second punching shape processing on the FPC small board, and the FPC small board is supported by the supporting substrate to prevent the FPC small board. Wrinkling or warping improves the punching accuracy, so that the FPC small plate can obtain a flat FPC single piece after the second punching shape treatment, which effectively improves the yield of the FPC single piece and reduces the occurrence of customer complaints. .
