Pressure Sensitive Mounting provides double-sided pressure sensitive transfer tape for a fast, reliable installation. 3M F9469PC transfer tape or equivalent may be used at ambient temperatures from -67°F to 300°F. Apply only on a clean, oil-free surface, and allow a 24-hour cure time. Consult the factory for other adhesives and extended liner options.

|Hook & Stick-on Gasket
Hook and stick fingers are ideal for flange mounting applications requiring low compression forces and small gap shielding.
SPIDER gaskets, featuring a continuous, smooth web of fingers on each side, are available in both Stick-on and Hook & Stick-on mounting configurations.
Non-conductive .010" thick adhesive may be specified for improved adhesion on rough surfaces. Conductive adhesives and extended liners are also available. Consult the factory for these options.
Special Mounting shielding strips can be installed by spot welding or soldering. Rivets can be used for the 375A and 500A profiles and conductive pressure sensitive adhesives are available. Consult the factory.
Tech-Etch "S" Series symmetrical shielding strips can be installed on extrusions specially designed to provide a useful free height. The drawing below illustrates guidelines for designing the extrusion.
Dimension "A" less allowance for initial contact is the compression range. Dimension "B" should be approximately .020" less than the open dimension of the shielding strip.
Track / Extrusion Mounting
Track or extrusion mounted symmetrical fingers provide a durable shielding solution for applications requiring bi-directional motion, such as drawers and plug-in modules.
TR Series Track is typically installed with plastic rivets, but is also available with pressure sensitive tape for adhesive mounting. The track can be installed prior to the assembly of the finger strips to avoid damaging the fingers. See below. Photos at illustrate several methods of retention, including "T" Retaining Caps. Retention stops can also be incorporated in the sheet metal.
Plastic rivets can be used to install Track and as rivet stops to retain shielding on a track as shown below and in the photo on the right. When used on a flange, the hole diameter for the rivet should be .125". Two rivets are available: PR45 and PR60.
"T" Retaining Caps can also be used to hold shielding on the Track.
Track in the left photo shows two shielding retainer options: Plastic Rivet Stop on the left and "T" Retainer on the right. Right photo shows the same track with shielding snapped into place.
Snap-on Slot and Edge Mount Symmetrical fingers using single or double fingers are very economical for applications such as sliding drawers, doors, rack-mounted assemblies and covers. They perform well in bi-directional applications and the snap-on capability makes them easy to install.
When continuous shielding is required the V Series or VE Series utilizing the same snap on mounting feature can be used. Available repeating finger patterns for the V and VE Series are shown here. Consult Tech-Etch for the availability of other patterns.
Track - Pressure Sensitive Transer Tape Mounting
Perhaps the easiest track mounting option is with double sided pressure sensitive transfer tape. Simply apply on a clean, oil-free surface, and allow a 24-hour cure time.
Omni Track is designed to provide a track type mounting for single finger applications. It is typically supplied with pressure sensitive tape for adhesive mounting. Holes are available for rivet mounting.
Econo Track has self-fastening clips and optional retention to provide the most economical method of mounting Symmetrical Fingers. Installation requires the fingers to be slid on from either end. Track and strip are then pressed into .12" diameter flange mounting holes. Flange thickness varies from .02" to .07". At right Econo Track is shown separately next to shielding strip and then combined.
