Ultra-high resolution cameras enhance defect detection accuracy

16 Jul 2019

With 101 Mpixels and 151 Mpixels respectively the new VC-101MX and VC-151MX cameras from Vieworks provide the ultra-high resolution needed for increased detection accuracy of cracks and defects on silicon wafers or solar cell panels, or for failure analysis of integrated circuits. FPD, BGA and PCB inspection also benefit from the ultra-high resolution. Fast frame rates and a CXP interface increase sample throughput to improve yields and productivity.

The uncooled VC-101MX and VC-151MX versions feature the latest IMX461 and IMX411 CMOS image sensors from Sony. The VC-101MX-9 offers up to 8.7 frames per second at 11656 × 8742 resolution. For even higher resolution applications, the VC-151MX-6 offers up to 6.2 frames per second at 14192 × 10640 resolution. Equipped with the Vieworks’ innovative technologies proved by the world’s top FPD manufacturers, the VC-101MX and VC-151MX cameras offer not only highly uniform images but also high speed image processing capabilities.

Cooled versions of these cameras, the VP-101MX and VP-151MX, utilise the same sensors with the same resolution and frame rates, but provide enhanced sensitivity.

These cameras use thermo-electric Peltier (TEC) cooling technology to maintain the operating temperature of the image sensor at up to 15 degrees below ambient temperature. This provides the stability needed for long camera exposure times which lead to increased sensitivity for the most demanding of applications.

Vieworks’ thermoelectric cooling technology uses the Peltier effect to lower the temperature. It was originally developed for the medical market and continues to be used extensively there. It features a special heat dissipation design throughout the camera from the internal components to the housing. This dissipates heat away from the image sensor to minimise noise and ensures that any moisture is removed from the cold surfaces.
