As shown in FIG. 3, each input / output printed wiring 28 has a distal end portion disposed on the outer peripheral portion of the substrate 18 and a base end portion connected to the printed wiring of the printed wiring board 12 (not shown). A rectangular connection land 30 is formed at the tip of each input / output printed wiring 28. These connection lands 30 correspond to a plurality of terminals 36 of the connector 34 connected to the operation check jig 32 via wiring. Further, notches 38 for guiding the connectors 34 are formed on both sides of the plurality of connection lands 30 on the outer peripheral portion of the discard substrate 18, and the connectors 34 are guided by the notches 38 to the outer periphery of the discard substrate 18. By being connected, the plurality of terminals 36 of the connector 34 and the plurality of connection lands 30 of the discard board 18 are electrically connected.

  In addition, on the side opposite to the input / output printed wiring 28 via the printed wiring board 12, a plurality of connecting printed wirings 40 serving as contact points for connecting the assembled boards are disposed between the discarded board 18 and the printed wiring board 12. , It is formed across the connection point 22 of the printed wiring board 12. These printed wirings 40 for connection are for electrically connecting the printed circuit boards 10 to each other (the discarded substrates 18 that are independent of each other), and have basically the same configuration as the input / output printed wiring 28. It is said that.

  That is, the distal end portion of the connection printed wiring 40 is disposed on the outer peripheral portion of the discarded substrate 18, and the proximal end portion is connected to the printed wiring of the printed wiring board 12. A rectangular connection land 42 is formed at the tip of each connection printed wiring 40.
