Mechanical penetration is clearly a possible explanation (given the thin layer), though I have attempted to be careful when applying the probes to only use the side & not apply significant pressure. I think if the oxide layer naturally present in atmosphere were so easily breached, terminating...

Mechanical compliance is present - the aluminum plate is compressed against the conductive paint with foam. The plastic will have a CTE that is close to that of Aluminum so displacement will be minimal. If 'conduction enhancement' products prove insufficient to maintain continuity, we'll move...

Thanks for your input. I am actually having one of the other aluminum parts nickel plated (using electroless nickel plating), not only for conductivity, but also for mechanical benefits. Surface treatments like plating or Alodine (chemical conversion) are also used to address oxidation in...

Thanks for the input. Unfortunately, I'm unable to post pictures. A simplified description is a plastic box (sprayed with conductive paint), with a metal (6061) plate lid that drops into a groove at the top. The conductive paint at the groove will provide continuous contact with approximately...

I'm using aluminum alloy (6061-T6 sheet at the moment) to construct a chassis for mechanical support of an assembly. This chassis also serves as part of an EMI mitigation system (RF, GHz range), so I need to ensure electrical continuity between the chassis and other components of the system. I...
