When wiring the test fixture and socket modules, use low hydrochloric acid solder (HP 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 (HP part number: 0890-1496).
