ELECTRONIC CIRCUIT DEVICE HAVING MULTIPLE WIRING BOARDS

摘要

PROBLEM TO BE SOLVED: To provide an electronic circuit device of high density, which can reduce the rise of a temperature while the complication of constitution and work is suppressed. SOLUTION: A base plate 4 has columns 42 and 43 erected perpendicularly to a main face from the main face of the main plate 41 of the base plate 4. The step faces 421 and 431 of the columns 42 and 43 support a printed circuit board 1. The top faces 422 and 423 of the columns 42 and 43 projected from the opening of the printed circuit board 1 support a printed circuit board 2.
