Abstract
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.
