Control system for ablating high-density array of vias or indentation in surface of object

Abstract

An control system for controlling movement of a product to be imaged relative to a laser and operation of a laser. The control system comprises a mechanism for obtaining drill position data from a data storage device. The control system further includes a mechanism for simultaneously sending necessary signals to alter a path of a laser beam emitted by the laser relative to the object to be imaged. The control system further includes a mechanism for providing a feedback to indicate that the path laser beam, from the laser to the product to be imaged, is suitably altered. The control system further includes a mechanism for firing the laser beam for one of burning, drilling or forming a desired formation in a surface of the object to be imaged. The control system further includes a mechanism for returning the control system, when necessary, for reading further drill position data from the data storage device.
