Abstract

PURPOSE:To increase the part mounting density of an electronic device by increasing the number of connecting terminals and parts mounting area of a single in-line module without increasing the external size of a board. CONSTITUTION:Semiconductor elements are mounted on both the surface and rear of a flexible board 1 provided with connection terminals 2 and insulating members 4 are stuck between the terminals 2 and board 1. Since parts can be mounted on internal side faces of the board 1 and the terminals 2 can be electrically separated from each other on both the surface and rear of the board 1, the numbers of connection terminals and mounted parts can be doubled without increasing the external size of the board 1 from that of the conventional board.

In the conventional module described above, the component mounting portion has the front surface 5A and the back surface 5 of the substrate 5.
Since it is limited to B, if the number of mounted components is increased in order to make the module highly functional, the outer dimensions of the substrate 5 must be necessarily increased. As a result, it has been difficult to satisfy the demands for downsizing and high functionality of electronic devices which have become stronger and stronger in recent years, and this has hindered the expansion of the applicable range.
