1700 Wafer Reader Mount Conversion
The 1700 reader can be mounted either horizontally or vertically depending on the
positions of the read window and light trap (see Figure F-0-1). The 1700 can be easily
converted from one mounting configuration to the other. In the following example, a
horizontal mount 1700 is converted to a vertical.
NOTE If possible, perform these steps within a cleanroom environment (Class 1000 or better) at an
electrostatic discharge (ESD)-safe work station. Use cleanroom-approved gloves to avoid
fingerprints on the read window. If the conversion is not done in a cleanroom, there is a possibility
of introducing "artifacts" on the optics. Also, depending on the Class of the cleanroom where the
reader will be used, the reader may no longer meet Class specifications after the conversion has
been done.
To convert the mount configuration:
1 Using a .050 inch Allen wrench, remove the two 2-56 x 3/16" button head screws that
attach the light trap, and the two screws that attach the read window.
