Abstract:
A chip package (200) includes a carrier (20), a chip (22), a second conductive means (26) and a transparent cover (28). The carrier (20) includes a base (24). The chip is mounted on the base and has an active area (222). The second conductive means electronically connects the chip with the conductive means. The first adhesive means is applied around the active area of the chip. The transparent cover is mounted to the base of the carrier. The cover is adhered with the first adhesive means so as to define a sealing space (32) for sealing the active area of the chip therein. It can be seen that the active area of the chip is sufficiently protected from pollution by the small volume of the sealing space.
Abstract:
A digital camera module (100) includes a lens barrel (20), a lens holder (22), an image pick-up module (26), and a protective member. The lens barrel defines a central hollow, and has at least one lens (202) received therein. The lens holder defines a central hollow. The lens barrel is movably received in the lens holder along an axis of the lens holder. The image pick-up module is arranged to receive light from the lenses. The protective member is configured for preventing dust and/or particle contamination associated with a relative movement of the lens barrel and the lens holder falling onto the image pick-up module.
Abstract:
A lens module (200) includes a barrel (20), a lens (30) and a shielding layer (51). The barrel includes a screening end (21) and a mounting end (22) positioned opposite to the screening end, and defines an aperture (23) in the screening end. A diameter of the aperture reduces in a direction from the screening end to the mounting end so that the aperture has a large diameter and a small diameter. The lens is received in the barrel. The shielding layer made of an opaque film is mounted on the screening end and defines a receiving hole (511) aligned with the aperture. The receiving hole has a diameter being in a range of the large diameter and the small diameter.

An image sensor chip packaging method includes: first, providing a carrier (20). The carrier includes a base (21) and a lead frame (23). The base has a chamber (214) defined therein. The lead frame has a plurality of conduction pieces (233). The conduction pieces of the lead frame are embedded in the base and are spaced from each other. An image sensor chip (30) is then mounted in the chamber. The image sensor has a photosensitive area (301) and a plurality of chip pads (302). A plurality of bonding wires (40) is then provided. Each wire electrically connects a corresponding chip pad of the image sensor chip and one of the exposed ends of a corresponding conduction piece of the carrier. A holder (50) having a holding cavity (54) is then provided. Finally, the carrier is then mounted in the holding cavity of the holder.
