3.3. Location of the photosensitive area

The photosensitive area is not marked neither on the front nor on the backside of the IC. As a visible reference, a metal ring of the IC can

be used. From the solder ball side it is visible. Also from the front side (photosensitive area) it can be seen with a camera which is sensitive

in the near infrared wavelength domain (950 .. 1'150nm).
