Questions about Helidge

Based on reviews, listing data and website checks · updated yesterday

What is Helidge?

Helidge is an engineering company based in Spokane, Washington, that designs and certifies precision vacuum and electromagnetic boundary interfaces. The business focuses on custom ultra-high vacuum (UHV) flange interfaces with knife-edge sealing geometry and helium leak testing with documented sensitivity down to 10⁻¹⁰ mbar·L/s. They also engineer electromagnetic boundary feedthroughs with measured shielding effectiveness and MIL-STD-461 EMC protocol capability, producing an Acceptance Test Report with each shipment.

How are Helidge's services organized across different portals?

The company operates as a parent brand with three sub-portals, including Helidge Systems for government and industry capability statements and RFQs, and Separatrix for R&D and SBIR/STTR identity. Another portal, Spukanee Systems, is reserved for regional and heritage identity and is not yet active. These portals speak to different audiences while maintaining the master Helidge brand.

What specific features define their vacuum boundary interfaces?

Helidge offers custom UHV flange interfaces featuring knife-edge sealing geometry and OFHC copper gaskets with a sub-micron finish of Ra < 0.4μm. They provide dual-hermetic certification where one engineered interface is certified against two distinct boundary failures, ensuring nothing crosses the boundary that isn't supposed to.

What standards and protocols are used for their electromagnetic feedthroughs?

For electromagnetic boundaries, Helidge engineers feedthroughs with measured shielding effectiveness in dB and impedance-matched coaxial feedthroughs. They adhere to MIL-STD-461 EMC protocols and provide NIST-traceable calibrated certification to ensure proven and documented performance.

What is the significance behind the name Helidge?

The business name Helidge compresses Helios, the sun, and the etymology behind helium, their leak-test gas, with edge representing the knife-edge seal. The name also references the plasma scrape-off layer in a tokamak, making every word in the name do triple duty.
