た。[Problems to be solved] In the conventional printed board warpage prevention structure by attaching reinforcing jigs, it is necessary to select a jig according to the external dimensions of the printed board 10, or a special jig is required for each printed board. There are disadvantages in that it is costly to prepare the jig, as it is necessary to prepare the jig, and it takes time and effort to attach and remove the jig, resulting in poor workability. For example, when electrical components are mounted near the periphery of the printed board 10 as shown in FIG. 3, it is necessary to use a reinforcing jig 17 of a special shape so as not to interfere with the electrical components.

形成するものとする。 The above-mentioned disposable board 2 is formed by providing V-grooves 5 as shown in the figure on both the front and back sides of the printed board 1. The thickness of this V-groove 5 is as follows:
It is extremely thin, so that the disposable substrate 2 can be separated from the printed board 1 at the V-groove 5. In addition, the above-mentioned disposable board 2
shall be formed at the time of creating the original image in the design of the printed board 1.

貫通孔２ａと対応して孔３ａが設けられている。 In the part of the disposable board 2 of the printed board 1,
A warpage prevention member 3 is fixed to each. The warpage prevention member 3 is made of a hard material and is formed into an L-shaped cross section and approximately the same width and length as the sacrificial substrate 2. The reason why the warpage prevention member 3 is L-shaped is to provide sufficient strength against bending. The warpage prevention member 3 is provided with a hole 3a corresponding to the through hole 2a of the disposable substrate 2.

By providing several through holes at arbitrary positions on the disposable board and attaching a warpage prevention member formed into an L-shaped cross section to the disposable board using rivets, the disposable board can be equipped when designing a printed board. However, if the holding members and rivets are prepared in advance, it is possible to prevent printed board warping by simply crimping the rivets by the assembly worker, and there is no need to select a jig or special jig, reducing costs. It has the effect of connecting.
