Shielding Resources Group, Inc. now offers 100% lead free honeycomb waveguide vent material. This material is provided to eliminate any and all concerns of lead contamination by airborn particles.

This material exceeds all domestic and international requirements for lead free electronics and is environmentally friendly. SRG's unique and proprietary manufacturing process includes applying a thin coating of 100% tin to the raw base strip base material.

The thickness of the coating is extremely critical and must be within .0015"-.002". After the base strip material is formed, cut to the desired length and assembled as a sheet, it is placed in an oven. Under a controlled set of parameters the temperature is raised until the tin coating is allowed to flow via capillary action, a process we have named fusion bonding. Once cooled, the sheet becomes a bonded or fused honeycomb matrix offering structural and RF intergrity.

Ideal for Foil RF Shielded ICD 705 Tempest SCIF Rooms, up to 100dB

To insure each manufactured sheet maintains the required performance level in terms of shielding effectiveness, SRG has implemented a very stringent Quality Control and Assurance Program which couples 100% visual inspection along with shielding effectiveness testing performed by a NVLAP approved independent test agency

Universal RF Shielded Honeycomb Air Filters

Minimal Resistance to Air Flow

Honeycomb design combines the highest shielding performance with the least resistance to air flow. Cell geometry allows the maximum amount of open space while maintaining the RFI shielding requirement of the enclosure.
