PURPOSE:To provide a double-sided mounting printed substrate and a mounting method therefor, adapted for reducing the number of steps of switching a production facility inexpensively and many kind and small quantity production. CONSTITUTION:A large-sized printed substrate 20 is formed of printed substrates 21, 22, 23, 24 and disposable substrates 25, 26. Patterns, mounting components and mounting positions of the front surface of the substrate 21 and the rear surface of the substrate 22, the front surface of the substrate 22 and the rear surface of the substrate 21, the front surface of the substrate 23 and the rear surface of the substrate 24, and the front surface of the substrate 24 and the rear surface of the substrate 23 are the same. Surface mounting components 29 are mounted on the front and rear surfaces of the substrates 21, 22, 23 and 24 by one type of a production facility. Discrete components 30 are brought into close contact with each other on the front surface of the substrate 22 and the rear surface of the substrate 21. And, leads of the rear surface of the substrate 22 and the front surface of the substrate 21 are soldered. |
