MANUFACTURE OF PRINTED WIRING BOARD

摘要

PURPOSE:To facilitate interconnection between the circuits on printed wiring boards and realize the low cost interconnection without degrading electric characteristics by a method wherein the land part of a thin printed wiring board is put on the land part of a thick printed wiring board which has a smaller land part area than the thin printed wiring board and an electric component is inserted through an aperture common to both the land parts and the thick printed wiring board, the thin printed wiring board and the electric component are made to be linked and electrically continuous. CONSTITUTION:The land part 3 of a thin printed wiring board 4 is put on the land part 2 of a thick printed wiring board 1 which has a smaller land part area than the thin printed wiring board 4. An electric component 6 is inserted through an aperture 5 common to both the land parts 2 and 3 with its terminal part or the like and the thick printed wiring board 1, the thin printed wiring board 4 and the electric component 6 are made to be linked and electrically continuous with solder 7. The aperture 5 common to the land part 2 of the thick printed wiring board 1 and the land part 3 of the thin printed wiring board 4 can be drilled by a conventional drilling process or punching process.
