Holland Shielding Systems BV has developed fingerstrip gaskets and metal grounding products for shielding and grounding. We have a large stock and deliver very fast!
Our range of beryllium-copper fingerstrips and contact strips provides cost-effective long-term EMI/RFI shielding, without any risk of degradation as a result of repeated opening and closing of the enclosure, or of bending of the beryllium-copper fingers. The Be/Cu fingerstrip is also referred to as Be/Cu fingerstock.
Modern electronic equipment often requires EMI/RFI shielding and an EMI/RFI-shielding gasket in order to avoid EMI/RFI radiating and to prevent interference from outside sources.
EMI/RFI gaskets that were designed and manufactured utilizing the strengths of beryllium and copper (Be/Cu) are the industry standard throughout the world. Starting with the emergence of RFI/EMI problems in the early days of military electronics, Be/Cu EMI/RFI shielding gaskets have been the solution of choice.
Apart from beryllium-copper, we also offer shielding and custom-engineered stamping in stainless steel, brass, phosphor bronze and other special alloys.
The Be/Cu fingerstrips are available in a variety of surface finishes, with or without tape or conductive tape. These Be/Cu fingerstrips can be delivered within 5-10 working days.
For applications where a small dynamic range is required and a clip-on mounting is preferred. Also for use where high temperatures or other design considerations preclude the use of adhesive-mounted gaskets.
Mounting through holes in your construction. You can mount the Fingerstrip by pushing it into position.
Thanks to their self-adhesive tape, these beryllium-copper shielding gaskets provide easy and secure mounting.
For small gaps and screwed applications. For narrow electronic shielding applications.
Ideal for 90° applications, where the fingerstrip has to be mounted onto the surface perpendicular to the finger compression area.
Circular fingerstrips are used for grounding and EMI shielding in high-frequency equipment and for forming large-diameter, round-contact rings.
These fingerstrips are very easy to bend and are therefore suitable for round and very dynamic contacts.
EMI fingerstock, fingerstrips and spring contacts for shielded Faraday-cage doors, electrically conductive doors and lids.
Surface-mount spring contacts for EMI shielding and grounding at the PCB level.
Determine the correct size of the mounting area (See Figure 1.)
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.
With the Holland Shielding Systems BV standard configuration there are the following mounting methods:
For more information see Figure 2.
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.
Most clip-on styles are available with retaining lances which enhance the spring grip onto the mounting surface.
Holland Shielding Systems BV shielding designs incorporate two types of adhesive tape on many of the gaskets.
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)
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.
