The jig for electrical inspection is formed on the bottom surface or the upper surface of the casing for actually electrically connecting the wiring pattern of the wiring substrate, and the electric inspection jig is connected to be used for inspection. A plurality of connectors (pins) that transmit electrical signals (measured) to the external wiring of the tester or the like are formed on at least one side of the casing.

In addition, the electric inspection head is provided with wirings electrically connected to the probes of the plurality of probes in the housing, and is also provided with a plurality of connections on the fixture body for electrical inspection. Wiring of each connector of the device (needle) is electrically connected. In addition, the wiring of the jig for electrical inspection and the wiring of the jig for electrical inspection are electrically connected to each other (for example, refer to Patent Document 1).

In the case of the electric inspection jig, if the number of inspections of the wiring board increases, the probe of the jig for the electric inspection wears and deteriorates. Therefore, the jig for electrical inspection is provided for the electric inspection jig. It is detachable, and when the probe is deteriorated, it can be appropriately repaired by removing the jig for electrical inspection from the jig for electrical inspection.

On the other hand, the wiring pattern of the wiring board varies depending on the model, and the number of connectors (needle) and the number of wirings for the electrical inspection jig of the electrical inspection jig, and the number of wirings, and the electrical inspection are required to be changed. The number of probes and the number of wires for the jig head are required. For this purpose, the type of each wiring board needs to be prepared for the electrical inspection jig. Therefore, it is necessary to prepare a plurality of jigs for electrical inspection in accordance with the type of the wiring board, and there is a problem that the cost for performing electrical inspection is inevitably increased.

In addition, when replacing the jig for electrical inspection according to the type of the wiring board, when replacing the jig for electrical inspection, it is necessary to perform the following operation, that is, to be attached to the main body of the electric inspection tool to be used. The cable of the connector (needle) is successively removed, and is successively mounted to the connector of the body of the new electrical inspection jig to be used. Generally, the number of pins of the connector is up to several thousand, so it takes a long time for the cable to be removed and installed for such a connector. Therefore, there is a problem that the time required for performing the electrical inspection of the wiring substrate is inevitably prolonged.

In addition, when the jig for electrical inspection is replaced in accordance with the type of the wiring board, the wiring board for electrical inspection must be aligned with the jig for electrical inspection, and the electric inspection of the wiring board is also performed. The time required is necessarily long-term.

On the other hand, in the manufacturing process of the wiring board, when the electrical inspection as described above is included as an essential step, the cost required for the manufacture of the wiring substrate is also increased, and the time required for manufacturing is prolonged. .

In addition, with respect to similar and identical constituent elements, the same reference numerals are used for all drawings.

As shown in FIG. 6 and FIG. 7, the jig for electrical inspection 20 of the present embodiment has a through hole 111H penetrating in the thickness direction substantially at the center of the first casing 111 of the jig body 11 for electrical inspection. A screw member 117 is inserted into the through hole 111H. The screw member 117 is composed of a head portion 117A, a shaft portion 117B, and a screw portion 117C. The head portion 117A is exposed from the upper surface 111C of the first casing 111, and the screw portion 117C is also exposed from the lower surface 111D of the first casing 111. Further, the through hole 111H is formed so as to be partitioned by the wall surface material of the cover shaft 118 so that the first wire 113 provided in the first casing 111 does not come into contact with the screw member 117 inserted into the through hole 111H.

On the other hand, a thick portion thicker than the other surface is formed on the upper surface 131C side of the third casing 131 of the electrical inspection jig connecting body 13, and a thread for the screw member 117 is formed substantially at the center thereof. The portion 117C is screwed into a threaded hole 131H.

In the present embodiment, the needle-shaped member 115 is not attached to the lower surface 111D of the first casing 111 of the jig body 11 for electrical inspection, but is formed by a flange 114 that extends through the opening of the through hole 111H.

Therefore, it is not necessary to replace the jig 11 for electrical inspection in accordance with the type of the wiring board to be inspected, etc., so that the cost required for electrical inspection of the wiring board can be reduced. Further, since the number of connectors (needles) and the number of the first wires 113 of the jig 11 for electrical inspection can be fixed, there is no need to perform an operation of attaching the body 11 to the jig 20 for electrical inspection to be used. The cables of the connectors (pins) are sequentially removed, and are successively attached to the connectors (pins) of the body 11 of the new electrical inspection jig 20 to be used. Further, since it is not necessary to replace the jig body 11 for electrical inspection, the alignment of the jig for electrical inspection with respect to the wiring substrate to be electrically inspected can be simplified.
