摘要： A tertiary positioner system (80) of this invention employs X- and Y-axis translation stages (86, 88), galvanometer-driven mirrors (64, 66), and a fast steering mirror (“FSM”) (120) to direct a laser beam (90) to target locations (121) on a workpiece (92). A positioning signal is received by a low-pass filter (103) that produces filtered position data for driving the X- and Y-axis translation stages. The actual positions of the X- and Y-axis translation stages are subtracted from the unfiltered positioning data to produce an X-Y position error signal for driving the galvanometer-driven X- and Y-axis mirrors. The actual mirror positions are subtracted from the actual positions of the X- and Y-axis translation stages to generate a positional error signal representing the difference between the commanded and actual positions of the laser beam. The positional error signal drives the FSM to rapidly correct any positional errors.

摘要： An electronic testing machine includes a plurality of test modules. Each test module has a plurality of contact pairs for testing electronic components. An apparatus and process for electrical test setup and calibration of the electronic testing machine includes a plate having at least one contact per track movable between test positions to electrically insert a test device selectively between any one contact pair, and a control program. The test device can be selected from a group consisting of a volt meter, a current meter, a precision voltage/current source, a calibration resistor, and a calibration capacitor. The control program can perform at least one test function through the plate. The test function can be selected from a group consisting of alignment verification, voltage/current source verification, insulation resistance (IR) leakage measurement verification, part-present contact check verification, capacitance and dissipation (CD) measurement verification, IR/CD compensation, and IR/CD calibration.
