Rotating Wafer Maps with Python

Rotating Wafer Maps with Python

As a production engineer, we often deal with map images. A wafer map is generated after CP testing, showing the pass/fail dies on the wafer. The packaging factory needs this map to select the pass dies for packaging. Sometimes, due to different notch orientations, the upstream and downstream wafer maps need to be rotated 90° … Read more
