Service Provides Custom RF Gasket Shielding
Addressing high-performance aerospace and electronics applications, Saelig now offers EECL's custom RF FIP gasket shielding. The shielding upgrade leads to customized, automated form-in-place (FIP) gaskets and microwave absorbers. These include conductive elastomers for cavity resonance suppression and environmental sealing. They're designed to fit on high-frequency RF PCBs to provide compartmentalized shielding and cavity resonance suppression.
Featuring low outgassing and wideband suppression from 10 MHz to 100 GHz, EECL’s premium custom RF and microwave solutions deliver superior electromagnetic isolation and RF performance. They can provide an attenuation of greater than 100 dB of incidence in K, Ku, Ka, L, S, C, X bands.
EECL enclosures, which are plated with high-loss tangent nickel, offer exceptional suppression of electromagnetic interference (EMI) and resonance, and are fully customizable with precision machining and plating processes.
Designed to enclose the customer’s PCB as part of the finished product, EECL can screen around connectors, on side walls, and provide a complete EMC shield. The internal surfaces are precision-roughened to optimize RF isolation by reducing internal coupling, while the external surfaces are polished smooth.
EECL’s advanced microwave absorber is chemically bonded to the roughened metal surfaces. This ensures full cavity resonance suppression without the need for adhesives, which can compromise performance.
The isolation gasket is a form-in-place, silicone elastomer can be applied in layers as thin as 30 mils. When precisely CNC-applied, it provides intricate gasket sections that achieve up to 100-dB isolation for reliable, repeatable results. In addition, EECL gaskets enable easy assembly, reusability, and stable performance in both high- and low-volume runs.
