AMI Semiconductors AMIS-20639 PI3039 contact image Sensor (CIS) Sensor chip is a linear array image Sensor chip with a 600 elements per inch resolution. The Sensor chip is fabricated with AMI Semiconductorsproprietary CMOS image sensing technology. Since this image Sensor chip is intended for CIS module applications, multiple numbers of these Sensors will be serially cascaded to form a linear scanning image array of arbitrary length. These Sensors are butted end-to-end on a printed circuit board (PCB). The Sensors are mounted using the chip-on-board technology to form scanning arrays with various lengths
