Caution
Electrostatic Breakdown

Keep glass window clean saturating cotton swab alcohol lightly wiping surface, allow glass dry, blowing with filtered Care should taken avoid mechanical thermal shock because glass window easily damage. Prevent generation static electricity friction making work with bare hands putting cotton gloves non-charging working clothes. Discharge static electricity providing earth plate earth wire floor, door stand work room. Ground tools such soldering iron, radio cutting pliers pincer. necessarily required execute precaution items static electricity. right mitigate precautions confirming that trouble rate within prescribed range.
Window Glass

Incident Light
sensor sensitive infrared light. Note that infrared light component degrades resolution PRNU sensor.
Mounting
This package sensitive mechanical stress. Toshiba recommends using inserters mounting, instead using lead forming equipment.
Soldering
Soldering solder flow method cannot guaranteed because this method have deleterious effects prevention window glass soiling heat resistance. Using soldering iron, complete soldering within seconds lead temperatures 260°C, within three seconds lead temperatures 350°C.
