How to shield - Fingerstrips

Determine the type of fingerstrip you need

By following these steps, you can easily determine which fingerstrip you need for your application

1. Proper size

Determine the correct size of the mounting area (See Figure 1.)

2. Dynamic range of compression

Each shielding gasket is compressed to a certain distance, depending on the design. A positive contact force can usually be assured when the gaskets are compressed up to 25% of their relaxed height or more.

3. Attachment methods

With the Holland Shielding Systems BV standard configuration there are the following mounting methods:

• 2100 series Clip-on mounting fingerstrips
• Instant tac adhesive
• Conductive adhesive
• Solder
• Weld
• Hardware
• Snap-on 2200 series

For more information see Figure 2.

4. Correct orientation

Many of the Holland Shielding Systems BV gasket designs depend on the active contact surface (top) being engaged at, or behind, the cross-sectional centre line. To assure the proper angle of engagement, the guidelines below should be followed for best results.

Retaining lances for clip-ons

Most clip-on styles are available with retaining lances which enhance the spring grip onto the mounting surface.

Adhesive tape specifications

Holland Shielding Systems BV Shielding designs incorporate two types of adhesive tape on many of the gaskets.

Instant tac adhesive

Application: for areas where the two opposing surfaces can be connected by contacting at least one point of the shielding gasket's profile on each surface.

Temperature range: -50 °F (-46 °C ) to +300 °F (+149 °C)

Conductive tac adhesive

Application: for areas where the two opposing surfaces can be connected by contacting one point of the shielding gasket's profile on one side and Conductive tac on the other.

Temperature range: -50 °F (-46 °C ) to +300 °F (+149 °C)
