Camera module for use in e.g. personal digital assistant, has conductive welding lead connected to signal terminal of composite printed circuit board, and under fill formed around connection zone between lead and signal terminal

摘要

The module has a composite printed circuit board (21) with a flexible printed circuit board (213) that is placed between two rigid printed circuit boards (211, 212). A perforation is formed in the board (21) for penetrating through the board (211). An image detection chip (22) is arranged on the board (211) and includes a conductive welding lead (23) and an image detection zone. The lead is connected to a signal terminal (211A) of the board (21). An under fill (24) is formed around a connection zone between the lead and the signal terminal. An independent claim is also included for a method for assembling a camera module.
