Abstract
The present invention relates to an improved system and method for manufacturing flexible circuit boards (FSBs) using optical alignment and various bonding systems. The invention provides an improved process to connect together the layers of rigid-flex, flexible, and printed circuit boards while maintaining alignment of the layers prior to and possibly after a lamination step. An optical alignment system is provided, a preferred arrangement is enabled as an automated pinless bonding system (PBS), for securely gripping, aligning, transferring, and clamping, bonding and moving a bonded FSB employing a multi-axis orientation. An alternative manual optical alignment and bonding system is provided.
Claims4
A registration system for bonding a rigid-flex panel layup of a plurality laminate elements in a selected stack orientation, the system comprising:
- a first optical measurement system for receiving said layup, for imaging portions of said layup, and for determining a first reference orientation data set of said layup relative to a desired orientation of said layup;
- a computer operation control system for determining a required correction factor between said determined first reference orientation data set for said layup and said desired orientation of said layup;
- a pin-less alignment and positioning system for receiving said required correction factor positioning instructions from said computer operation control system and for positioning each said layup from a top position to said desired orientation during a bonding of said layup;
- and
- wherein said pin-less alignment and positioning system includes a pre-alignment loading station;
- a plurality of imagery cameras on said pre-alignment loading station, said plurality of imagery cameras enabling a pre-alignment of a layup;
- and
- a gripper assembly employs at least a vacuum plate system, a cam adjustment system movable relative to said vacuum plate system for adjustment, and a motion sensor system for gripping and positioning each said layup in said desired orientation, whereby said registration system enables an alignment and bonding operational use.
