Abstract:
The present invention provides a method for fabricating a quad flat no-lead package structure, comprising a chip carrier and at least a chip. The chip is disposed on the top surface of the chip carrier, while the back surface of the chip carrier includes a plurality of flat no-lead conductive leads as I/O pads of the chip carrier for the external circuitry. A plurality of pads, corresponding to bonding pads of the chip, is disposed on the top surface of the chip carrier. The aforementioned package structure can employ wiring bonding technology, flip chip technology or surface mount technology to attach the chip to the chip carrier.
Abstract:
A camera module is provided. The camera module comprises: a holder having an upper portion, a lower portion, and a bottom; a lens member held on the upper portion of the holder; a hinge disposed on the bottom of the holder; a cover coupled to the hinge and to the bottom of the holder, the cover being allowed to open and close to cover the bottom of the holder, the cover and the lower portion of the holder forming a space; and an image sensing and processing device disposed on the cover, wherein when the cover is close, the space can accommodate the image sensing and processing device.
Abstract:
A package structure for optical image sensing devices is disclosed. The package structure includes an image sensing integrated circuit chip having a light receiving side and a backside. The image sensing integrated circuit chip has a light sensing area on the light receiving side. A plurality of light sensing devices are arranged in the light sensing area for converting incident light into electrical signals. A plurality of bonding pads are arranged along one or two sides of the light sensing area. Black sealing glue is asymmetrically coated on the outskirts of the light sensing area. The black sealing glue has at least two coating widths. A glass lid is glued over the light sensing area with the sealing glue.
Abstract:
A pointing device includes two lenses with wide and narrow view angles respectively. In a short distance range, the pointing device utilizes the lens with wide view angle to increase visible range. In a long distance range, the pointing device utilizes the lens with narrow view angle to increase size of a formed image of a reference point. In addition, the pointing device senses images through both of the lenses with wide and narrow view angles to obtain rotational information. The pointing device can provide not only positional information but also angular information.
Abstract:
A camera module is provided. The camera module comprises: a lens; a holder having a lower portion, the holder holding the lens; a circuit board; and an image sensing and processing unit including an image sensing device and an optional signal processing device stacked on and electrically connected to the image sensing device, the image sensing and processing unit being packaged on one side of the circuit board; wherein the holder is fixed on the circuit board, the image sensing and processing unit inside the lower portion of the holder. Further, if the circuit board is a flexible circuit board, then a hard plate can be disposed on the other side of the flexible PCB corresponding to the image sensing and processing unit in order to enhance the mechanical strength.
