Publication number: 20060276059Abstract: A Flat Flex Connector (FFC) has connector flanges embedded in its insulated electrical traces. The flanges engage electrical circuits in a camera module such as a CMOS or CCD and are clamped into electrical engagement. The opposite end of the FFC makes electrical contact with another electrical device such as a semiconductor circuit. The assembly allows electrical connection of two or more devices in a confined space in which the electrical device are not easily aligned for electrical contact.Type: ApplicationFiled: April 21, 2006Publication date: December 7, 2006Applicant: Neoconix Inc.Inventors: Larry Dittmann, John Williams, William Long
