Completes metrology and Lifetime test in 3 minutes<br />
The automated <strong>Ingot</strong> <strong>Inspection</strong> <strong>System</strong> performs<br />
lifetime and conductivity testing, measures ingot weight,<br />
length, diameter and perpendicularity, and then laseretches<br />
and verifies a 2-D barcode at both ends of the<br />
ingot. Test results are recorded to disk or network, and<br />
system performance and calibration can be confirmed at<br />
any time by running an on-board “standard ingot” stored<br />
within the tool. The tool responds to commands from a<br />
client’s factory automation system, but can also function<br />
as stand-alone tooling within a laboratory environment.<br />
<strong>Ingot</strong> weight is precisely calculated by four load cells,<br />
with dimensions and face perpendicularity measured by<br />
laser transducers. Conductivity testing is performed by<br />
an off-the-shelf test head utilizing four tungsten carbide<br />
needles, delivering output accuracy of approximately<br />
0.3%. Lifetime testing is via client-provided hardware<br />
integrated into the system by <strong>DWFritz</strong>. The PC-based<br />
controls system includes a custom-designed touchscreen<br />
interface, enabling the user to monitor or manually<br />
control the complete metrology process.<br />
