PCB Mapping.

During PCB mapping the PCB-camera measures the cross fiducials on a highly precise glass

plate. This glass plate is calibrated with a measurement machine and this data is taken into

consideration during the measurement sequence.

The linearity of the X and Y axis guidance system for PCB-camera movement is measured

within the entire placement area.

RV-Mapping.

During RV-mapping the C&P head places the new calibration tool onto the mapping glass board

exactly at the nominal positions of the glass plate. The PCB-camera measures the placement

accuracy of these placements.

The linearity of the X and Y axis guidance system for C&P head movement is measured by the

segment offset bottom at these positions.

IC-Mapping.

During IC-mapping the Twin head places the new calibration tool on the mapping glass

board exactly at the nominal positions of the glass plate. The PCB-camera measures the

placement accuracy of these placements.

The linearity of the X and Y axis guidance system for Twin head movement is measured by

the segment offset bottom at these positions.

Attention:

For application on double transport, please turn Version 3 for 90 degree;

The arrows on the mapping plate indicate the direction.

Calibration of Mapping Plates

Mapping plates must be recalibrated every four years.

The date for the next recalibration is on the calibration certificate.

Please contact the SCC in Munich for detailed information.
