Information Needed to Start Up ProjectInformation Needed for New PCAP Project Start Up:1. CAD drawing for touch panel (1:1 Ratio needed if given in a PDF file. The file must be clearlyreadable.2. The drawing must indicate the construction of the touch panel, interface, FPC location, andDimensions.3. The location of FPC to fold and assemble into the LCD needs to be indicated so thatengineering can make the proper layout.4.
