Micro-G® Operational Background
Once the hardware setup is complete the system is ready to be used.
A general idea of how the Micro-G® functions is needed for the user
to fully understand the parameters behind a Micro-G® process.
The Micro-G® head attaches to the polishing fixture and has a
micro-stepping drive mechanism integrated so the user can control
the polishing fixture position with respect to the polishing platen
position at micron level accuracy. Thus, it is important to understand
the protrusion length of the object to be polished from the bottom
surface of the polishing fixture before moving forward with a pro-
cess. By knowing the protrusion length of the object for polishing the
user can determine how much movement is needed to put the object
in contact with the polishing film. Imaging setup using the DE2910
Opti-Spec Video Scope allows the user easy methods to determine
fiber positions.
The equipment software will position the fixture to a “Home” position
upon power up of the equipment. This is used as a starting point for
referencing the highest up position of the polishing fixture. There is
approximately 3500 microns (3.5mm) of space between the fixture
and the polishing surface when the system is in the “Home” position.
Space between will vary based on the pad thickness.
After “Home” reference is established, the user will define positional
fixture movements down from “Home” towards the polishing platen.
Thus, if the object to be polished protrudes 300 microns below the
polishing fixture, an additional 2700 microns of downward movement
by the fixture are needed to put the object to be polished in contact
with the polishing film.
