  This utility model relates to the field of electronic and electrical equipment, particularly to the technical field of electronic and electrical printed wiring boards, and more specifically to a fixed mold for precision machining of the wiring board.

  With the continued development of electronic and electrical technology and the spread of integrated circuit applications, the application range of printed wiring boards has become wider. Especially, as the circuit scale has increased, various circuit control functions have become more complex. If a continuous chip wiring board is increasingly applied to manufacturing crafts, and one or several single chips are defective in the continuous chip, the regular continuous chip wiring board cannot perform a normal circuit function.

  In the prior art, for a continuous chip wiring board having a plurality of defective single chips, it is necessary to cut out the defective single chips and replace them with non-defective single chips for repair. Such continuous chip wiring board replacement repair is an environmental protection technology that is adopted in the production of wiring boards and is highly efficient, highly profitable, and greatly reduces waste. Various disadvantages of disposal can be avoided.

  However, since the localization accuracy is not high in the conventional repair technique, the displacement of the replaced wiring board is increased, and such a defect extremely restricts the development of this technique.

  In order to solve the above-mentioned problem of insufficient accuracy in the conventional technology, a cutter with high accuracy was adopted, but since a method of positioning pins is normally adopted for a mold for positioning a wiring board, Abnormal cases such as pin slippage and pin dropout are likely to occur during the process of use, cutting accuracy could not be ensured, and the final wiring board replacement and repair accuracy was affected.

  The precision fixing pin of the fixing mold for precision machining the wiring board is a precision fixing bolt.

  When a fixed mold for precision machining of this utility model wiring board is adopted, a plurality of integrated wiring boards processed directly by the mold forming program with high precision numerical control sealing on this mold board There is a stereotactic pin, and multiple precision detachable stereotactic through-holes and precision fixing bolts that match it are distributed around this stereotactic pin, realizing fully automatic machining of the stereotactic pin and simplifying the manufacturing craft process In addition, it is possible to ensure that the error of the pin size and position is minimized, and to greatly improve the localization accuracy of the wiring board. In addition, the stereotaxic pin and the mold substrate are integrally connected, and fundamentally, it is possible to eliminate abnormal situations such as pin misalignment and dropout in the process of use, and to ensure reliability during the process of production. it can.
