Description:

Peripheral Imaging Corporation PI3042A CIS, Contact Image Sensor is a 400 dot per inch (dpi) resolution, linear array image sensor chip. The sensor chip is processed using PIC’s proprietary CMOS Image Sensor Technology. Designed for cascading multiple chips in a series, the image sensor chips, using chip-on-board process, are bonded end-to-end on a printed circuit board (PCB). This bonding process allows users to produce variable CIS module lengths in increments of chip array lengths. Hence, the wide variety of image reading widths can easily be applied to the numerous document scanners, found in facsimile, as well as, the narrow width scanners, such as, those found in check readers, lotto tickets, entrance gate tickets and other office automation equipment which requires a wide variety of scanning widths.

Figure 1 is a block diagram of the imaging sensor chip. Each sensor chip consists of 128 detector elements, their associated multiplexing switches, buffers, and a chip selector. The detectors element-to-element spacing is approximately 62.5 μm. The size of each chip without scribe lines is 8080 μm by 385 μm. Each sensor chip has 7 bonding pads. The pad symbols and functions are described in Table 1.
