Description
AMI Semiconductor’s AMIS-720341-A (PI3041A) contact image sensor (CIS) chip is a 300 dots per inch (dpi) resolution, linear array image sensor chip. The sensor chip is processed using a CMOS image sensing technology and it belongs to the Image Sensor Product Line (ISPL) group within AMIS. Designed for cascading multiple chips in a series, the image sensor chips use a chip-on-board process. They are bonded end-to-end on a printed circuit board (PCB). This bonding process allows the CIS module manufacturers to produce variable CIS module lengths in increments of the chip array lengths. Hence, the modules are easily applied in a large number of document scanners found in today’s facsimile market. Some examples of these large document scanners are those that produce wide format maps and architectural drawings, down to the narrow width scanners, such as those found in check readers, lotto tickets, entrance gates tickets, etc. This is not to exclude office automation equipment, which requires an even more variety in scanning widths, as well as those with special mechanically configurations.
