摘要： A method and of determining scanner coordinates to accurately position a focused laser beam. The focused laser beam is scanned over a region of interest (e.g. an aperture) on a work-surface by a laser scanner. The position of the focused laser beam is detected by a photodetector either at predetermined intervals of time or space or as the focused laser beam appears through an aperture in the work surface. The detected position of the focused laser beam is used to generate scanner position versus beam position data based on the position of the laser scanner at the time the focused laser beam is detected. The scanner position versus beam position data can be used to determine the center of the aperture or the scanner position coordinates that correspond with a desired position of the focused laser beam.

摘要： A system and method of probing work pieces is described. A first and second arm each having a pivot point and a guide end are pivotally coupled together at the respective pivot points. A probe tip holder is coupled to at least one of the first arm or the second arm. A guide means guides movement of the guide ends of the pivotally coupled arms, such that movement of the guide end of the first arm and the second arm move the probe tip holder in a plane parallel to the work piece surface.

摘要： A material machining system for machining a workpiece (PCB, PWB etc.) for drilling blind vias. The system includes a laser supply system (20, 26, 30) for supplying discrete machining beams (22a, 22b) that are separate from each other. A deflecting devices (28, 32) is provided for deflecting each of the discrete machining beams to generate multiple independent beams at a plurality of positions within a field of operation on the workpiece. A scan lens (34) having an entrance pupil configured to receive the multiple independent beams from the deflecting devices is provided proximate to the entrance pupil of the scan lens. A computer is used for controlling the deflecting devices to change the respective positions of the multiple independent beams in at least one co-ordinate direction within the field of operation. The deflecting devices include galvo/mirror pairs at the entrance pupil of the scan lens. This is accomplished since the scan lens has a relatively large entrance pupil and the mirror parts are small. The advantage of this arrangement is the ability of all beams to access a full working field (typically 2×2 inches) on the workpiece simultaneously, so that the highest efficiency of laser power utilization is achieved.
