Maintenance
Make sure that terminals are not connected to the instruments before you repair the
test fixture. When you remove the bottom cover, loosen the four flathead screws
using a screwdriver, as shown in the following figure.
When wiring the test fixture and socket modules, use low hydrochloric acid solder
(Agilent part number: 8090-0433) to prevent the flux in the solder from spreading
unnecessarily. When soldering, make sure the terminals do not make contact with
each other. After soldering, make sure that there are no lint bridges so that leakage
current is minimal.
Keep the following items in mind when repairing socket modules:
•
Place a ferrite bead at the 8 mm point of the terminal on the socket side and fix
the bead using epoxy adhesive.
•
Never allow the ferrite beads to make contact with each other.
•
For the three socket modules used for power devices, wrap the contact of the
wire and socket terminal using heat-shrink tube (Agilent part number:
0890-1496).
