and it cannot be replaced.
Slotless Contact Repair General Information 1-1

Equipment Required
But Not Supplied
The following items are required, but not supplied with this kit:
A microscop e with  x10 magnication and lighting.
A source of clean, dry, compressed air or nitrogen.
Incoming Inspection
Refer to Table 1-1 to verify receipt of all parts in this repair kit.
The foam-lined storage case provides protection for the comp onents
in this repair kit during shipping. If the case or components app ear
damaged, set aside the kit and all packaging materials and contact
the nearest AgilentTechnologies oce listed at the back of this
manual.
If either of the following conditions exist, notify your nearest Agilent
Technologies oce:
The shipping contents are incomplete.

for the carrier's inspection. AgilentTechnologies will arrange for
repair or replacement of incomplete or damaged shipments without
waiting for a settlement from the transp ortation company.
Precision Slotless
Connectors
When properly used, a precision slotless connector should ha
ve the
same lifespan as a standard slotted connector. AgilentTechnologies
designed the precision slotless contacts to mate with all connectors
within a connector series, but the connectors must meet published
interface dimensions.
CAUTION
Mating a connector that do es not meet published specications can
damage a precision slotless connector. For this reason, ensure that
any device you connect is within its sp ecications.

Repairing A Slotless Contact
Introduction
If you susp ect a problem with the slotless contact, make a visual
inspection to determine if there is damage. As you use a connector,
dirt and metal particles can accumulate in and around the slotless
contact. In extreme cases this accumulation can render the contact
non-functional. Often, simply cleaning the contact xes the problem.
This chapter provides pro cedures on how to clean both the inner
contact and the center conductor, how to reinstall the inner contact,
and how to test for functionalit y. Also provided is a pro cedure on
how to replace the inner contact.
Repairing a damaged slotless contact is a six-step process:
1. Gage the connector. Because connector mechanical tolerances can
be very precise (on the order of a few h
undredths of microinches),
even a perfectly clean, unused connector can cause trouble if it
is mechanically out of sp ecication. If the pin depth is out of
specication, the connector is damaged beyond the capabilities of
this repair kit, and the device must b e repaired or replaced by
AgilentTechnologies.
CAUTION
Never use an out-of-sp ecication connector.
2. Under  x10 magnication, inspect the connector to determine the
damage.
3. Remove the damaged inner contact.
4. Inspect the center conductor. If it is undamaged, clean it.
5. Install the replacement inner contact.
6. Test the slotless contact.
Slotless Contact Repair Repairing A Slotless Contact 2-1

Inspecting A
Damaged Slotless
Contact
Inspect the contact under  x10 magnication to dene the problem.
Usually you can make the repair without disassembling the device to
which the precision slotless contact is attached.
Inspect the slotless contact to see if any of the following conditions
exist:
The inner contact has one or more ngers b entinward or crushed,
preventing proper contact to the male pin (see Figure 2-1).
If so, go to step 1 of \Removing A Slotless Contact."
The inner contact has one or more ngers broken (see Figure 2-2).
If so, go to step 2 of \Removing A Slotless Contact."
The inner contact is pushed inside the center conductor and will
not make contact with the mating connector's male pin (see
Figure 2-3).
If so, go to step 3 of \Removing A Slotless Contact."
The end of the center conductor is dented or scraped near where it
touches the inner contact (see Figure 2-4).
If so, the slotless contact may b e damaged b eyond the capabilities
of this repair kit, and the device must b e repaired or replaced by
AgilentTechnologies.

Removing A Slotless
Contact
Step 1
If one or more of the inner contact's ngers are b entinward or
crushed, you must straighten or remove those ngers b efore you
remove the entire inner contact. Figure 2-5 shows both the inner
contact and the center conductor.
Figure 2-5. The Inner Contact and Center Conductor
a. Under magnication, carefully try to insert the remo
val to ol (see
Figure 2-6).
b. If the damaged ngers preventyou from inserting the to ol, use the
tweezers provided to either move aside or remove the damaged
ngers (see Figure 2-7).
CAUTION
Avoid damaging the center conductor, which houses the inner
contact. Do not touch the tweezers to anything but the damaged
inner contact. Do not, under any circumstances, use anything to
squeeze or clamp on to the center conductor that might cause
damage.
c. After you move or remove the damaged inner contact ngers and
can insert the inner contact removal to ol, go to step 3.
2-4 Repairing A Slotless Contact Slotless Contact Repair

Figure 2-6. Inserting the Removal Tool
Figure 2-7. Moving a Damaged Finger
Step 2
If one or more of the inner contact's ngers are broken, you must
remove that nger b efore you remove the entire inner contact:
a. Under magnication, lo ok down inside the inner contact and
lo cate the broken nger or ngers.
The ngers mayhave already fallen out. If so, continue with
step 3.
b. If you can see the broken ngers inside the inner contact, turn the
device upside down and gently tap on it (see Figure 2-8).
Using this gentle tapping, try to force the broken ngers to drop
out or at least move forward far enough so that you can remove
them with the tweezers (see Figure 2-9). Do not, under any
circumstances, use anything other then gentle tapping.
c. After you remove the broken inner contact ngers and can
carefully insert the inner contact removal to ol, go to step 3.

Figure 2-8. Freeing a Broken Contact Finger
Figure 2-9. Removing a Broken Contact Finger
Step 3
If the inner contact is pushed inward and no longer makes contact
with the mating connector's male pin, you must remove and replace
the inner contact:
a. Under magnication, insert the removal to ol into the damaged
contact far enough so that it touches the b ottom of the inside of
the inner contact.
b. Turn the to ol clo ckwise to engage the to ol coupling thread with
the thread on the inside of the contact (see Figure 2-10).
c. Occasionally the inner contact spins with the to ol, preventing the
to ol from engaging. If this happ ens, apply a small amoun
t axial
pressure to the to ol and continue to turn it clo ckwise.
2-6 Repairing A Slotless Contact Slotless Contact Repair

d. Once the to ol is engaged by 2 turns, you can remove the inner
contact. Pull the to ol and inner contact straight out away from
the center conductor (see Figure 2-11 ).
CAUTION
Do not damage the center conductor as you remove the inner
contact.
e. Unthread the broken inner contact from the removal to ol and
discard the contact; it cannot be repaired or reused.
