Abstract
In accordance with the invention, an open frame circuit assembly mounted on a planar substrate is provided with a low flow impedance voltage guard. The low impedance guard comprises a lower frame member extending peripherally around the assembly, an apertured top member overlying the assembly and a plurality of spaced apart struts supporting the top member from the frame. The top member and struts have rounded surfaces to preserve streamlines in air flowing over the assembly, and all openings and spacings are sufficiently small to preclude accidental human contact with the assembly.
