RF Door
Use and Maintenance
The RF Enclosure requires following simple maintenances to perform as designed.
Cleaning the Floor inside the RF-Enclosure
The floor inside the RF-Enclosure can be wiped clean by using a damp mop or cloth. Use of excessive water poured onto the floor can cause damage to the shield ground isolation.
Cleaning cabinets, furniture, door and window molds.
It can be wiped clean by using a damp mop or cloth.
Cleaning of the RF-Door Frame
The RF door frame should be cleaned up to six (6) times a year to eliminate the build-up of dust and oils deposited by handling and traffic. This can be accomplished by the use of an abrasive sponge which can be wiped over the contact area. Thereafter the whole frame should be wiped clean with a dry cloth.
RF-Door, Frame and shielding gaskets
The RF door utilizes EMI shielding gaskets to provide the necessary electrical contact between the door and its’ frame. This contact must be uniform and can be monitored by looking at the edge of door itself. A pattern showing where these fingers make contact is a good indication. The marks should be consistent in length and frequency around the entire frame.
If it is noticed that the pattern around the RF door is inconsistent or if the fingers are bent or missing, replacement is a simple procedure.
There are a few types of EMI shielding gaskets used on the RF door and frame.
On the top and sides of the door frame there are self-adhesive contact fingers and elastomer knitted mesh gasket and on the bottom of the door there are clip-on fingers and conductive fabrics over foam shielding gaskets.
If fingers on the sides or top of the door frame are missing, the strip with the damaged fingers should be removed with a knife. It is important that any remaining glue residue be removed with the use of acetone or denatured alcohol. The new strip of fingers can be cut with scissors to the appropriate size for replacement.
If the section is adjacent to the closing latch or lock, the cut-out for these can be made in the same manner. The protective tape on the back of the finger contact is to be removed and the new strip aligned with the brass profile and pressed firmly against it to make good contact.
To replace the contact fingers on the bottom of the door, the door design does not require that the door be taken off the hinges and frame. Simply remove all screws on the bottom trim piece or brass angle. The L-shape piece can now be removed from the door and the damaged finger strip can be slid out and replaced with a new one. It is not necessary to replace the entire strip, merely the portion of the strip which is damaged. The different sections of the strip should be placed as close as possible to each other without overlap for best shield attenuation. Smaller replacement sections should be positioned in the center of the trim piece, with the larger sections maintained at both ends.
When completed the brass angle is re-attached to the bottom of the RF door and fit snug and flat against the door itself and between the trim that is attached to the sides. For this the brass angle must be located correctly in the groove before screwing it back.
Caution: Placing any object between the door and the frame such as an extension cord, using hard materials to pry or keep the door open, or by catching the fingers with loose clothing might cause physical damage of the gaskets.
