Removing and
Installing Chucks
When you change to a new device package, select the appropriate chuck
as shown in the chuck selection chart (see Figure 4-13).
CAUTION: Chucks are released from the beam suddenly. If the beam is
positioned over the SPA pins or input track, the sudden
release may damage those areas.
Change the chuck with the beam directly over one of the two main plate
recesses. Keep the beam raised by holding it up with two fingers while
you use a downward pulling/twisting motion to remove the chuck. With
one hand on the beam for support, insert the new chuck by lifting it
straight up until it snaps into position.
