This shielding structure is constructed by 2mm pan-type galvanized panels and assembled with special fastener M10 and high-performance gasket to ensure a long-life RF shielding attenuation. It is a bent flange that is welded on the corners to close up the “pan” profile.
The proper selection of anechoic material is critical to your success. The chamber can, and does fail qualification testing due to poor anechoic material or the wrong type. The key to selecting the right microwave absorber(s) is the material’s reflectivity performance. Our recommendation is for a thorough technical discussion with AR applications engineers, in order to identify the proper solution for your requirements.

While the pan type shielding system is a very practical design, it is highly recommended that it be installed by experienced and qualified technicians in order to maintain performance and efficiencies.
This will depend on the scope of the project, refurbishment of small chambers, i.e. absorber replacements can be as little as a few days and construction of large EMC chambers such as a 10M Chamber with a 5M quiet zone can be 12 to 14 weeks.
Once the shielding installation is completed, the chamber will be tested on RF attenuation before the installation of the anechoic materials. Once the full installation is completed, the chamber will be tested by 3rd party for NSA, sVSWR and UFA compliance to verify the anechoic performance of the chamber before the system integration process.
