Appendix F
In-Sight 1700 Wafer Reader Mount Conversion
The In-Sight 1700 wafer reader can be mounted either horizontally or vertically
depending on the positions of the read window and light trap (see Figure F-1). The
In-Sight 1700 wafer reader can be easily converted from one mounting configuration to
the other. In the following example, a horizontal mount In-Sight 1700 wafer reader is
converted to a vertical mount.
NOTE If possible, perform these steps within a cleanroom environment (Class 1000 or better) at an
electrostatic discharge (ESD)-safe workstation. 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
wafer reader will be used, the wafer 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.
