Verification and repair station of PCBS

A verification and repair station for examining a printed circuit board (PCB) at a plurality of predetermined co-ordinates thereon for enabling an operator to classify suspected faults and to effect manual repair thereof if necessary. A worktable is provided for securing thereon the PCB in precise registration with an origin of the worktable and a fixed camera produces a magnified image of an illuminated area of the PCB. The co-ordinates are stored in a memory of a computer whilst a translatory drive is coupled to the worktable and to the computer for moving the worktable under control of the computer through mutually orthogonal axes so that successive co-ordinates are aligned with the camera. A visual display monitor coupled to the computer and to the camera for displays the magnified image of the illuminated area of the PCB and the computer is programmed to generate a drive signal in respect of any one of the co-ordinates which lies in a half of the worktable remote from the operator prior to its being aligned with the camera. A rotary drive coupled to the worktable and to the computer is responsive to the drive signal for rotating the worktable through 180 DEG .
