An image sensor package is one of the most important components of any digital imaging device. It is a combination of an image sensor (such as a Charge Coupled Device or active-pixel sensor) mounted on an LGA (Land Grid Array) printed circuit board, held in place by a plastic holder, and covered by double-sided antireflective glass. This document describes the techniques for packaging such imaging devices, widely used in digital still/video cameras, digital camcorders, mobile cameras, and security cameras.
