The embodiments of the present invention are described in detail below:

The method for testing the electrical property of the multi-number combination panel according to the present invention comprises the following steps:

Step 1: Combine a plurality of single material number plates into one production plate 10. The six first single material number plates 12, two second single material number plates 13, one third single material number plate 14, and two fourth single material number plates 15 are shown together in FIG. A production board. Wherein, the single number plate has a plurality of network units. The material of each of the single-number plates is the same as the thickness, the number of laminations, the thickness of the copper, the type of ink, the surface process and the manufacturing process. The network unit includes a branch formed by series and/or parallel connection of electronic components such as resistors, capacitors, and inductors, that is, each electronic component in the network unit is not isolated, and each of the electronic components is electrically connected to each other.

Step 2: Obtain network unit location information of each of the single material number boards.

The step of obtaining network unit location information of each of the single material number boards includes the following steps: generating the network unit information according to each layer circuit pattern of the single material number board; and the outer circuit line of the single material number board The graphic is matched to the drill tape of the production board 10; the flying probe testing device determines the network unit position information according to the outer circuit pattern and the network unit information.

Step 3: The flying probe testing device sequentially performs electrical performance testing on each of the network units according to the location information of each of the network units. The electrical performance test includes a test of whether the network element is open and/or shorted. When the flying probe test device tests the open and/or short circuit information of the network unit, the four flying pins are respectively contacted with the pads or the soldering rings on the production board 10 at both ends of the network unit, and the capacitance and/or resistance information is electrically tested to determine. Whether the network unit is shorted or open, and record accordingly.

The clamp of the flying probe test device clamps the splint area 11, and the flying needle is directly tested with the test points of each single material board during the test. Electrical contact makes good contact with the test points at the edge of the single-piece plate.

The production board 10 is provided with a plurality of laser alignment holes 16, and the laser alignment holes 16 illustrated in FIG. 1 are four and are respectively located at four corners of the production board 10. The flying probe testing device first performs laser alignment with the laser alignment hole 16 before performing electrical performance testing on the production board 10 to determine the position of each of the single material number plates on the production board 10. The flying probe testing device sequentially performs electrical performance testing on the single-number plate, and performs laser alignment with the laser alignment hole 16 to determine the single-number plate before testing the electrical performance step of the single-material plate. The position on the production panel 10. The flying probe test device aligns the laser alignment hole 16 before the electrical property test on the single-number plate on the production board 10, and determines the position of the single-piece plate on the production plate 10, so that the accurate identification of the single can be facilitated. The position information of the material network board of the material board can facilitate the electrical connection test of the network unit through the flying needle and the network unit end pad or the soldering ring, and the electrical performance test of the single material number board is fast and accurate.

The same single-number plate on the production plate 10 has two or more. Two or more of the same single-number plates can be freely typeset on the production plate 10. The flying probe testing device sequentially performs electrical performance tests on two or more of the same single-number plates. When the flying probe testing device tests that the network unit has open circuit and/or short circuit information, a corresponding error prompt is performed. Specifically, if the network is open or shorted during the test, the network coordinates of the wrong network are generated and Network number. After the error message is given, continue to test the electrical performance test of other network units and make corresponding records. Among them, the test software will mark the faulty unit with red shading, and the qualified unit will be marked with green shading. After the test is completed, the red unit coordinates will be repaired/discarded. If the repair is qualified, it needs to be retested. If it needs to be scrapped, then The unit is affixed with a scrap label (writing the defect name and responsible process, material number, etc.) and the electrical performance damage label. After being milled into small plates, the scrap is taken out and submitted to the MRB (disposable house) for recycling.

Alternatively, the electrical performance test of the current single-number board is stopped when an error message is given to a single material number board, and the electrical performance test of the single material number board that has not been tested for electrical performance is turned. In this way, the same single-number plate is placed in the same area on the production board 10, and the same single-number plate is sequentially tested for electrical performance by the flying probe test device, which can improve the electrical performance measurement of the production board 10. Test speed. And during the electrical performance test of each single material number board, if the acquisition network unit has open circuit and/or short circuit information, the corresponding error prompt is given, and the other single material number board is not turned to the electrical performance test. After the electrical performance test of the production board 10 is completed, after the production board 10 is cut into a plurality of small boards, the small board with the corresponding error prompt can be taken out for scrapping or recycling, and the test time can be saved and the work can be improved. effectiveness.
