Digital camera module and method for assembling the same
First Claim
1. A digital camera module comprising:
- a lens module comprising a holder, a barrel slidably received in the holder, and at least one lens element fixed in the barrel, the holder defining a plurality of channels therein, each channel defining an enlarged end opening;
a plurality of wires each received in a corresponding channel;
a focusing structure attached to the holder; and
a chip package comprising a plurality of pads formed on the surface thereof, the positions of the pads corresponding to the enlarged end openings of the channels;
wherein an amount of conductive adhesive is deposited on the pads and retained by the enlarged end openings of the channels, the lens module is attached to the chip package by means of the conductive adhesive, and each wire is electrically coupled to a corresponding pad so that the chip package is thereby configured for controlling the focusing structure to selectably drive movement of the barrel.

Abstract
An exemplary digital camera module (200) includes a lens module (20), a chip package (30) and a focusing structure (40). The lens module includes a holder (24) and a barrel slidably received in the holder. At least one lens element (222) is fixed in the barrel. The holder has several channels (246) defined therein. Each channel respectively has an enlarged end opening (2468) and receives a corresponding wire (28) therein. The focusing structure is attached to the holder. Several pads (36) are formed on the surface of the chip package. Each wire electrically connects with a given pad using a conductive adhesive (52), and, via such a connection, the chip package is able to control the focusing structure to drive movement of the barrel. The respective enlarged end openings serve to help retain the corresponding conductive adhesive proximate/adjacent a given pad.
