Setting Up
Inserting Other Devices
The programmer must be fitted with a Base and adapter appropriate for the
device you are using. When you insert a device into an adapter socket, consult
the illustrations on the adapter to determine device orientation. Most devices
are keyed so that they can fit into the socket only one way. For more
information, refer to the documentation included with the adapter.
9. Preventive Maintenance
Cleaning the Fan
Conductive Pad
Operate your programmer where the vent over the fan will not become
blocked, and remove any dust or dirt that accumulates on the fan vent.
The conductive pad (see Figure 2-20) is a key element in the MatchBook
technology. To help keep yields high and prolong the life of the pad, keep it
free of dirt and other contamination. We recommend you inspect and clean it
at least every 1000 device insertions or once a month, whichever comes first.

DO NOT REMOVE
The life of the pad also depends on the pin count and package type of the
device you are using. Different tolerances may result in different life cycles for
the pad. An increase in device insertion errors or continuity errors or a sudden
drop in programming yields may indicate the pad needs to be replaced.
Note: You may notice an indentation in the middle of the pad after
a number of insertions. The indentation is normal and does not
degrade the performance of the MatchBook. It is also normal for the
pad to show signs of discoloration as it is used.
Cleaning the Pad
Blow air over the pad to clean it. If you use compressed air, direct the air
stream from the front or back of the Base, not from the side.
CAUTION: To avoid lifting the pad off the circuit board, do not blow air
from the side of the pad.
