Abstract: A method for assembling the fingerprint identification module is provided. Firstly, a protective cover and a fingerprint sensing element are combined together. Then, the fingerprint sensing element is placed on the circuit board. Then, a triggering element is placed on the circuit board. Then, an adhesive thickness is obtained according to a predetermined thickness and the thicknesses of the protective cover, the fingerprint sensing element, the triggering element and the circuit board. Then, an adhesive film corresponding to the adhesive thickness is placed on the circuit board. Since the appropriate adhesive film is selected according to the demand, the thickness of the fingerprint identification module is substantially identical to the predetermined thickness.

Abstract: A method for assembling a fingerprint identification module is provided. During the process of cutting the sensing strip, the thin junction slices between the fingerprint sensors are retained. Consequently, the size of the top surface of the fingerprint sensor is close to a predetermined size. After the thin junction slices are cut, the concave structures are formed on the bottom surfaces of the fingerprint sensors. Consequently, the size of the bottom surface of the fingerprint sensor is smaller than the size of the top surface of the fingerprint sensor. Even if the cutting skew is generated during the cutting process, the fingerprint sensor can pass the size test. Consequently, the production efficiency is enhanced.

Abstract: An optical disc drive and a soundproof structure thereof are provided. The optical disc drive includes a case, a tray and a door. The case has a panel, which with the door forms the soundproof structure. The panel has an opening, an outer surface and at least a first rib on the outer surface and near the opening. The tray is in the case, the tray carrying an optical disc to enter and eject from the case through the opening. The door is disposed on the front border of the tray, having at least a second rib on a surface opposite to the outer surface of the panel, leaning against the outer surface of the panel away from the first rib by a gap. A noise transmitted outwards is reduced through a space encolsed by the first and second rib.

Abstract: A CD-RW resonance removing apparatus comprises a first holding-down plate where at least the driving plate, the sliding rods and the read/write head are mounted; a second holding-down plate to balance the total weight of the first holding-down plate and other components mounted on it; multiple elastic pads attached to the first holding-down plate, called first elastic pads, for connecting the first holding-down plate to the chassis frame; and multiple elastic pads attached to the second holding-down plate, called second elastic pads, connect the second holding-down plate to the first holding-down plate. The first and second elastic pads could be with different K values and damping values. The balancing weight by the second holding-down plate, the absorbing vibration by the second elastic pads, and the isolating vibration function of the first elastic pads, all together, eliminate resonance during operation.

The first holding-down plate connects to a chassis frame through a series of first elastic pads, and a second holding-down plate is connected in parallel to the first holding-down plate through a series of second elastic pads. Active components are installed on the first holding-down plate and the second holding-down plate.

Abstract: A resonance removing mechanism installed on CD-RW drive to remove resonance. The CD-RW drive contains a tray, a read/write head, a CD-RW driving plate and other components. All these components are installed on a chassis frame. The tray is controlled by the motor at the front of the chassis frame through a set of gears and a linking component so that it can expand and contract on the chassis frame. The read/write head is installed on the first holding-down plate together with the CD-RW driving plate through two sliding rods. The first holding-down plate connects to the chassis frame through a serial of the first elastic pads, while a serial of the second elastic pads is installed and connects to the second holding-down plate parallel to the first holding-down plate to form a resonance removing mechanism.
