Operating Basics
Handling the cLGA
Interface Clip (Probe
Head)
The cLGA interface clip in the probe head should always be handled with care.
Keep the following points in mind when you handle the clip:
Always handle the cLGA interface clip by the outer edges, and be careful to
avoid the contacts in the center. Do not touch the contacts with your fi ngers,
tools, wipes, or any other devices. (See Figure 5.)
Figure 5: Proper handling of the interface clip
Do not expose the connector to liquids or dry chemicals.
If the board pad array needs to be cleaned, only use isopropyl alcohol and
lint-free cloth as described above.
Immediately following cleaning, or immediately prior to placement of
connector to circuit board, blow off the board pad array and connector contact
array with clean, oil-free dry air or nitrogen to remove loose debris. First start
the blowing process by aiming away from the array areas, and then sweep
across the pad and contact arrays in a repeated motion to remove loose debris.
Place the connector onto the board pad array using the bosses or locator pins
for alignment. Use care to prevent incidental contact with other surfaces or
edges in the connector contact array area prior to board placement.
Always store the probe head in the protective cover when not in use. (See
Figure 8 on page 12.)
