Abstract

Provided are a camera module constituted such that the conductive state of connecting terminals on two printed circuit boards is easily inspectable by visual observation when inspecting and a method for inspecting the camera module. This camera module has an anisotropic conductive film intervening between a plurality of first connecting terminals provided in a row arrangement on a first printed circuit board formed from a rigid circuit board or a flexible circuit board and a plurality of second connecting terminals provided in a row arrangement on a second printed circuit board formed from a flexible circuit board and creates conductivity respectively between the plurality of first connecting terminals and second connecting terminals by pressing with a pressure bonding head. The anisotropic conductive film is mixed with pressure coloration capsules, and before pressure is applied by the pressure bonding head, the outer edge of the anisotropic conductive film in a second direction orthogonal to a first direction, in which the plurality of first connecting terminals and second connecting terminals are adjacent to each other, protrudes from a location equivalent to that outer edge part or from that outer edge part in the second direction for either or both of the first printed circuit board or second printed circuit board.

Description

technical field

[0001] The present invention relates to a camera module in which two circuit boards are connected by interposing an anisotropic conductive film between a rigid circuit board or a flexible circuit board and a flexible circuit board, and an inspection method of the camera module. Background technique

[0002] Conventionally, an ultra-small camera module has been mounted on a small and thin portable terminal such as a mobile phone or a PDA (Personal Digital Assistant), thereby enabling not only voice communication but also image capture and communication.

[0003] Such a camera module incorporates at least an imaging lens and an imaging element including a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) image sensor. When the optical image of the subject is imaged on the imaging element through the imaging lens, it is photoelectrically converted and output as an image signal to external devices such as mobile terminal...
