Customer-Designed Cassette Configuration - Agilent Technologies E5035A Operation Manual

Customer-designed Cassette Configuration

Agilent E5022/E5023 allows the user to use a customer-designed HGA cassette. When you
use your own designed cassette, you have to let the system know the dimensions of the
cassette. This is prevent the cassette from bumping into the spindle and shroud. The
location of the HGA boss center and several points outside of the cassette must be specified
as shown below using a down face cassette. Since the up face is the line asymmetry of the
down face it is impossible to define the down face and up face separately.
Figure 3-5 Customer-Designed Cassette Dimension
The center location of the right side guide pin is defined as the origin of coordinates.When
a cassette has two guide pins on one side, the head pin becomes the origin.
The x and y coordinates of the HGA boss center is defined as the 'position'. From the x and
y coordinates, two or three location points must be specified in order to let the system
know the shape of the cassette. The user can specify certain points outside the cassette.
As shown in Figure 3-5 the outer area covered by the lines connecting Points 1,2 and 3
form what is called as the "permission area". The spindle and shroud is allowed to exist
within this area. On the other hand, the inner area is defined as the inhibit area where the
spindle is not allowed to exist.
NOTE
Although, the DLL functions of E5022/E5023 allows you to specify the locations for more
than three points of the outer area, the VEE measurement program supports up to three
points only. See the "hpe5022_hgaCassetteDimention" function in the programming
manual for details.
