Abstract: A method of this invention is for manufacturing a circuit board in which terminal fittings and electronic components are provided on a first surface of a main substrate that has the first surface and a second surface, a sub substrate that has a first surface and a second surface is arranged on the second surface side of the main substrate, and the sub substrate and the main substrate are connected by relay terminals. The main substrate and the sub substrate are formed in advance in a state of being connected in the same plane. During the method, the main and sub substrate are initially physical connected, at which time electrical components are attached to at least the main substrate. After physically separating the main and sub substrates, they are electrically connected.

Abstract: A printed circuit board with a terminal having a novel structure that enables terminals to stand on their own on the printed circuit board without using a seat, while reducing or eliminating damage to through-hole plating or an inner layer circuit. A printed circuit board with a terminal includes a terminal having soldering sections that are inserted, without being press-fitted, into through-holes of a printed circuit board and are fixed by soldering. The terminal has a fixation leg and the printed circuit board has a press-fit hole, the terminal is positioned and retained on the printed circuit board by the fixation leg of the terminal being press-fitted into the press-fit hole of the printed circuit board, and an inner circumferential surfaces of the through-holes are provided with plating, whereas an inner circumferential surface of the press-fit hole is not provided with the plating.

Abstract: The present invention provides a laminate printed board having a novel structure that is able to ensure alignment accuracy of the interboard terminals soldered to one printed board and that is also able to achieve a simplification of the process of soldering the interboard terminals. Through-hole lines in which a plurality of through-holes extend in lines are formed on a first printed board. Additionally, a press-fitting fastener hole is formed within the through-hole lines and a first end of an interboard terminal is press-fitted and fastened to the press-fitting fastener hole. Additionally, first ends of others of the interboard terminals are inserted through and flow soldered to through-holes on the first printed board.
