Title:
CIRCUIT BOARD AND ELECTRONIC CIRCUIT MODULE
Document Type and Number:
WIPO Patent Application WO/2017/164062
Kind Code:
A1
Abstract:
This circuit board (100) is provided with: a circuit board main body (1) in a rectangular parallelepiped shape having first to sixth faces; a first electrode (2) which is provided on the first face and includes first land electrodes (2a, 2b) and second land electrodes (2c, 2d); and a third electrode (4) which is provided on the second face and includes third land electrodes (4a, 4b) and fourth land electrodes (4c, 4d). The first electrode (2) and the third electrode (4) have a shape of 180° rotational symmetry with respect to a first axis (A) and a second axis (B), the first axis (A) passing through the centers of the first and second faces and being perpendicular to the first and second faces, and the second axis (B) passing through the centers of the fifth and sixth faces and being perpendicular to the fifth and sixth faces. An internal circuit is configured to be an identical electronic circuit in both the case where an electronic component is connected to the first electrode (2) and the case where the same electronic component is connected to the third electrode (4).
