A detection device and method of use thereof

Abstract

The invention relates to a detection device and an application method thereof. The detection device is used for detecting the electric property of a circuit board. The circuit board comprises a connector, a first branch circuit and a second branch circuit, wherein the first branch circuit comprises a goldfinger set, a first line and a first element; the first goldfinger is electrically connected to the connector through the first line and the first element; the second branch comprises a second goldfinger set, a second line and a second element; the second goldfinger set is electrically connected to the connector through the second line and the second element; the second branch circuit is connected in parallel with the first branch circuit; the detection device comprises a first conductive adhesive and a second conductive adhesive; the first conductive adhesive corresponds to the first branch circuit and is used for detecting the electric property of the first branch circuit; the second conductive adhesive corresponds to the second branch circuit and is used for detecting the electric property of the second branch circuit; the conduction control of the first conductive adhesive and the conduction control of the second conductive adhesive are mutually independent; and when the electric property of only one of the first branch circuit and the second branch circuit needs to be detected, only the corresponding first conductive adhesive or second conductive adhesive can be conducted.

Description

technical field [0001] The present invention relates to a detection device and its use method, in particular to a high measurable rate detection device and its use method. Background technique [0002] Generally, after the printed circuit boards, semiconductor packaging components or wafers with multiple detection points (such as electronic component contacts) are manufactured, they need to be tested by a special jig to confirm whether they are good products or whether there is an open circuit phenomenon. . [0003] figure 1 For the schematic diagram of circuit board electrical testing in the prior art, please refer to figure 1 , there are a plurality of probes 111 on the detection fixture 110, which are used to contact the measuring point 123 on the circuit board 120 to realize electrical testing, and the measuring point 123 is electrically connected to the golden finger 121 and the connector 122, but, as figure 1 As shown, the measuring point 123 will be in an exposed s...

Problems solved by technology

There is a whole strip of conductive glue 211 on the detection jig 210, which is used to press and contact the golden finger 221 to realize electrical detection, but this detection method is not very high for the detection rate of the parallel branch, for example, different golden fingers 221 The branches connected to the connector 222 are connected in parallel, so if there is an electrical problem in one of them, the detection jig 210 cannot detect it, so figure 2 Although the detection method improves the electrostatic problem, the problem of diffraction is not high and the measurable rate is not high.
