Purpose: To give fixture users pointers on fixture maintenance and care.
- Store in a protected place when not in use such as a metal cabinet or book shelf.
- Make sure that the shelf it sits on is clean. The installed standoffs will allow the fixture to sit without damage to the connectors.
- Check DC and RF connections periodically to ensure good contact and that damage has not occurred.
- Store the fixture in such a way as to allow objects to contact the bottom surface. Anti-static Styrofoam is OK. Doing otherwise may contribute to pin breakage or RF connector damage. Do not store on WIRE shelf racks.
- Periodic cleaning of the RF connectors and fixture in general is important. To clean the RF connectors:
- Choose a good quality Q-tip or cotton swab.
- Wet the swab in Isopropyl alcohol (strength at least 90%). Then place the swab into the connector and twirl it once or twice only.
- Remove any cotton fibers left behind with tweezers or blow them out with dry air.
- To remove debris from the Teflon insert, use a tooth pick or other sharpened instrument. Carefully wipe the insert being careful not to put pressure on the center conductor.
- Any dust or debris inside the fixture is best removed by a stream of compressed air (see Picture 1).
- Using Isopropyl alcohol (strength at least 90%) and a clean Q-tip or Kim-wipe, wipe the contact side of the RF and DC interfaces carefully (see picture 2). Also wipe the tips of the pogo pins themselves.
- Repeat step 1 for the contact pads of the socket (see picture 3).
- Use dry air to blow off any left over fibers left behind by the Q-tip and/or Kim-wipe.
- Inspect the socket for any broken or misaligned contacts.
- Replace bad contacts using the manufacturers prescribed replacement procedures.
- Use a mild stream of air and/or a soft artists brush to remove loose debris from the socket when needed.
- Follow the manufacturers prescribed cleaning process for debris that is not easily removed.
- In preparation to shipping the fixture the following steps should be noted.
- Wrap the fixture in two or more layers of anti-static bubble material. The bubbles should have a diameter of no less than 0.8 inches (2 cm). Styrofoam should not be used to protect pins during this process as it is a generator of static. Anti-static foam is OK.
- The box used should allow for at least 3"of isolation between the fixture and box (not including the thickness of the bubble wrap). As a general rule, use a box with the following specifications:
Single Wall Corrugated
Bursting Test 200 lb/sq. inch
Min Comb WT Facings 84 lbs per m sq ft.
Size Limit 75 inches
Gross Weight Limit 65 lbs
Min Dimensions 20"x20"x12"
- Place the wrapped fixture into the box and finish filling it with shipping material and then seal it well. Label the outside of the box "FRAGILE" or "DELICATE INSTRUMENTS" or similar.
