The present invention relates to a substrate unit and a substrate assembly, and a camera module using the same. The present invention may comprise: a first substrate part having rigidity; a second substrate part stacked on one surface of the first substrate part and having flexibility; a third substrate part extending outwardly from the second substrate part and having flexibility; and a reinforcing part which is disposed at a portion where the edge portions of the first substrate part and the third substrate part meet, the reinforcing part having a recessed portion which is formed by recessing the first substrate part inwardly so as to inhibit interference between the first substrate part and the third substrate part. The present invention is capable of resolving the interference between a rigid PCB and a flexible PCB and the tearing thereof by providing a reinforcing part in a connection portion of the rigid PCB and the flexible PCB.

An edge connector includes a first row of golden fingers and a second row of golden fingers. The first row of golden fingers is adjacent to a plugging end of the edge connector, and the second row of golden fingers is adjacent to the first row of golden fingers. In a plugging direction of the edge connector, each golden finger in the first row of golden fingers has a first end proximate to the plugging end and a second end opposite to the first end. A first end of a grounded golden finger in the first row of golden fingers is protruded from other golden fingers, and second ends of two or more than two golden fingers in the first row of golden fingers are not aligned with each other.

An RFID tag includes an RFID IC, flexible substrates including first wiring conductors and rigid substrates including second wiring conductors. Substrate surfaces of the flexible substrates include first regions connected to the rigid substrates and second regions that include opposite surfaces and are not connected to the rigid substrates. First conductor portions and second conductor portions included in the first wiring conductors are electrically connected to each other via the second wiring conductors. The RFID IC is connected to the first wiring conductors, the second wiring conductors, or both the first wiring conductors and the second wiring conductors.

A solid-state drive (SSD) includes a first rigid printed circuit board comprising a surface that defines a first plane. A second rigid printed circuit board of the SSD comprises a surface that defines a second plane that is substantially parallel to the first plane. A flexible interconnect couples the first rigid printed circuit board and the second rigid printed circuit board. The flexible interconnect partially encloses a volume. A capacitor is disposed within the volume.
