Description

Carrier Auto Alignment Device for Camera Module Anisotropically Conductive Film Bonder {Camera Module ACF Bonder Carrier Auto Align System}

The present invention is an apparatus that allows the bonding operation to proceed after automatically correcting the position of the carrier in the ACF bonder facility of the camera module process.

TCP, COF, FPC, etc. are electrically connected by crimp bonding the terminals to the wiring pattern of the LCD and PCB module, and a separate crimping device is required to perform such crimp bonding. It must be transported to the crimping position.
