Use Ingenuity to Ground and Shield Existing Electronic Equipment

September 13, 2011 2:43 pm | by Lee Stephens, Kollmorgen, www.kollmorgen.com | Articles | Comments

When building electronic equipment, it is imperative to understand the coupling mechanisms of electrical noise that creates Electro-Magnetic Interference (EMI). It is also much easier to preplan a method of abatement during the build of a machine rather than try to initiate a resolution once the equipment is built. However, in reality, it’s common to have to improve or otherwise develop procedures to prevent the noise from disrupting intended signals of existing equipment or designs.
