ことを特徴とするものである。A printed board with a reinforcing plate according to the present invention for achieving the above object has a rectangular printed board in which a plurality of insertion holes are formed along a predetermined direction, and a plurality of legs corresponding to the insertion holes. A printed board with an elongated reinforcing plate, wherein legs of the reinforcing plate inserted into the insertion holes are fixed by soldering, wherein the insertion holes are orthogonal to the fiber direction of the printed board. At each end of the two sides, the leg of the reinforcing plate has a protrusion projecting in the longitudinal direction of the reinforcing plate. The opposing portion and the side edge portion of the reinforcing plate in contact with the printed circuit board have a dimension smaller than the thickness of the printed circuit board and form a gap into which the printed circuit board is fitted. Things.

くなる。The reinforcing plate of the printed circuit board operates so as to prevent the printed circuit board from warping or cracking and bending of electronic component leads.
Thus, the strength of the printed circuit board is increased by the rigidity of the reinforcing plate, so that the printed board does not warp or crack. Further, the soldered temporary fixing portion of the reinforcing plate is more rigid than the electronic component lead, and since it is slightly longer, no external force is directly applied to the electronic component lead, so that the electronic component lead does not bend.
