Embodiment Construction
[0041] The present invention will be described in further detail below in conjunction with each accompanying drawing.
[0042] see image 3 , is a specific embodiment of the combined base used in the circuit board testing machine of the present invention. The circuit board testing machine includes several test points, which are usually connected to the base through cables or wires.
[0043]The combined base includes two unit bases that can be assembled; each unit base includes a regular-shaped base plate 101 . A plurality of conductive points 102 are disposed on one end of the substrate 101 , and a plurality of socket points 103 are disposed on the other end of the substrate 101 . The substrate 101 can be a multi-layer circuit board, and the electrical connections between the conductive points 102 and between the conductive points 102 and the socket points 103 can be realized in the multi-layer circuit board. Of course, the connection wires can be arranged in different laye...

The invention relates to a combined base and a jig for a circuit board testing machine. The seat includes at least one unit base, the unit base includes a substrate with a regular shape, a number of conductive points arranged at one end of the substrate, and a number of socket points arranged at the other end of the substrate; the conductive points are arranged in at least two conductive point matrixes, and the conductive points The matrix is arranged in the length direction of the substrate; the conductive points at the same position in each conductive point matrix are electrically connected to the same socket point at the same time. For testing machines with different test points, multiple unit bases of the present invention can be simply spliced, avoiding the trouble of making corresponding bases for each testing machine, and has the advantages of convenient use, good versatility, and low cost. The conductive point matrix of each unit base is arranged in the length direction of the plate, avoiding the defect that N conductive points are criss-crossed when they are connected to the same socket point. It has simple wiring and can design enough conductive points according to user needs.
Description
【Technical field】 [0001] The invention relates to an electrical performance testing device, in particular to a combined base and a fixture of a testing machine for testing short circuit and open circuit of printed circuits. 【Background technique】 [0002] After the circuit board manufacturer completes the production of the circuit board, the circuit on the circuit board must be tested for open circuit and short circuit. The prior art test equipment for circuit board short circuit and open circuit includes special testing machine, universal testing machine and flying probe testing machine, wherein the testing speed of flying probe testing machine is slow, mainly suitable for testing engineering samples, and used for mass production of circuit boards The test equipment is mainly a special test machine and a general test machine. [0003] The special test machine and the general test machine test the circuit board to be tested through the test fixture. A test fixture generall...
