Replacing a pogo pin
Hazardous voltages may be present on an installed probe card even after the output is
disconnected, that if contacted, may cause personal injury or death.
To replace a pogo pin:
1. Reset the tester hardware.
2. Remove the probe card from the probe card adapter assembly (see
(on page 3-10)).
3. Using a pair of needle-nose pliers, pull the defective pogo pin out of its socket.
The pogo pins are not symmetrical. Damage to the socket may occur if the pogo pins are
inserted incorrectly.
4. Locate the rounded end of the replacement pogo pin (see the following figure).

5. Insert the rounded end of the pin into the socket. The double-chisel tip, on the other end of
the pogo pin, must protrude out of the socket. This end of the pogo pin contacts a pad on the
probe card.
6. Reinstall the probe card.
