Abstract

Circuit panels, such as LCD panels, are inspected in-process and after final assembly to identify defects. Prior to final assembly, panels identified as having sufficiently few defects are repaired. Similarly after final assembly, panels identified as having sufficiently few defects are repaired. The inspection and repair systems are linked through a repair file. The inspection system identifies each defect by type and location and includes such information in the repair file. The repair system accesses such file and follows a prescribed repair method for a given type of defect at the location of such defect. Simple matrix panel defects include open line defects and line to line shorts. The inspection system includes an automated non-contact capacitance imaging system. The repair system may include a pair of lasers and a film dispenser. A first laser is used to selectively remove material and cut lines. The dispenser is for applying a liquid organic metallic film in the defect area. The second laser is for tracing a line in the film to form a conductive path repairing the defect.
