Pogo Pin Replacement Instructions
For N1020A TDR Probes with Spring Loaded
Ground Contacts
This Instruction manual is for all TDR Probes that have a Spring Loaded Ground Contact
Pin with a mating socket in the Probe. It will describe how to remove a pin (either to
move to a new hole, or because it is broken) and then how to replace a pin into the
desired hole. If you require further information please contact ICM. (See below for
contact information.)
In order to remove the Spring Loaded
contact pin (Pogo Pin) you need to use a
set of needle nose pliers. Use care when
squeezing the pin as you do not want to
damage it, but you must hold fairly
securely.
Hold the Pogo Pin firmly with the pliers
and pull it STRAIGHT out from the TDR
Probe.
Notice that the Pogo Pin is coming out of
the Probe along the axis of the mating
socket. If you do not pull straight out with
the pliers you could bend or break the Pogo
Pin.
After you have removed the Pogo Pin from
the Probe do a quick inspection to make
sure it was not damaged during the
removal. If it is ok proceed to the next step.
Pogo Pin Installation: Select the hole that
you wish to put the Pogo Pin in. (The holes
are laid out to have different RF to Ground
pitches for a wider range of applications.)
Again it is important to place the Pogo Pin
into the socket with a pair of pliers. Notice
that every effort is made to place the Pogo
Pin into the socket in a straight manner
along the common axis.
Use the pliers to push the Pogo Pin into the
socket as far as it will go. Do not force it at
this point.
After you have pressed the Pogo Pin into
the Probe as far as you can with the sockets
you will need to give it a final push to get
it the rest of the way into the prove. To do
this, use a solid, flat tool. (Perhaps the
opposite end of a pair of tweezers as in this
case.)
Push firmly with the flat tool to “pop” the
Pogo Pin into the socket. You should feel a
final movement in the Pogo Pin when it
secures itself into the mating socket.
After pushing the Pogo Pin into the Probe
you should see only the compressive part
of the Pogo Pin. (It should look similar to
the picture at the right.)
If you have any other questions or concerns please contact ICM.
