Abstract: A first circuit board has an electrode pattern, a ground pattern, a first through hole, and a second through hole. The first through hole penetrates through the electrode pattern. The second through hole penetrates through the ground pattern. A second circuit board has a signal line, an electrode terminal, and a ground terminal. The electrode terminal is extended from the signal line, and is electrically connected to the electrode pattern with the electrode terminal being inserted into the first through hole. The ground terminal is electrically connected to the ground pattern with the ground terminal being inserted into the second through hole, and has a width, a length, or an area or any combination thereof larger than a width, a length, or an area or any combination thereof of the electrode terminal.

Abstract: An optical modulating apparatus includes driver that is mounted on a printed circuit board such that a signal electrode pad and a ground electrode pad of the driver are exposed in an opening of the printed circuit board. An optical modulating device is mounted on the printed circuit board, opposing the driver across the opening. A flexible circuit board is disposed in the opening. An end of a signal terminal of the flexible circuit board is electrically connected to a signal electrode of the optical modulating device. An end of a ground terminal of the flexible circuit board is electrically connected to a ground electrode of the optical modulating device. The other end of the signal terminal is soldered to the signal electrode pad of the driver, and the other end of the ground terminal is soldered to the ground electrode pad of the driver.
