This is a vacuum fixture plate
to hold down LCD display modules for the iPad.
It will be used to drill out
the mounting screw holes because the plastic keeps breaking when the
screws are inserted because they are too small.

The groove for the O-ring seal is being machined. This
cord comes on a reel and once the proper length is determined, I cut the
ends of the cord on an angle and place it in the fixture so that when the
cord gets compressed it pushes the angled surfaces into one another
ensuring a leak free joint.

The bottom of the fixture showing the vacuum line
plumbing. The fixture is segmented into 3 zones with a separate vacuum
generator evacuating each zone.
The vacuum port “pin hole” was
engineered to be just large enough to allow for a good vacuum on each
display but small enough so that if 2 or 3 displays were to be dislodged
or otherwise leak, the vacuum generator could still keep up with the leak
and provide sufficient vacuum for the other displays in that circuit.

Here is a good shot of the O-ring seal as well as the
vacuum port (in the center of the cross hairs) and the grid.
