Abstract
PURPOSE:To make the interconnection of the lands easy as well as to make the packaging density high by making the wiring grating cylindrical. CONSTITUTION:On the side of a cylindrical printed wiring board 1, an LSI 2 is mounted through a parts stand 3, the lands 6 are interconnected by wiring patterns 4 and viaholes 5. Also, a lead 10A of the LSI 2 is electrically connected to a lead 10B of the parts stand 3. The lead 6 are placed at the contact points of the lead 10B and the cylindrical printed wiring board 1, and the wiring patterns 4 are placed along a wiring grating 7. The wiring patterns can be placed on both the surface and the rear. The connection of the wiring pattern on the surface and that on the rear is done by the viaholes 5 and the lands 6. Since part of the edge of the wiring grating 7 is eliminated by this, the electrical connections between the lands 6 becomes easy, whereby the packaging density of the LSI 2 and the like can be made high.
