Question concerning powder coating

post #1 of 7
Thread Starter 
So I'm looking at powder coating my case but the guy I talked to about doing it had a couple concerns. His concern was with RF insulation and grounding. He is concerned that the powder coat will trap RF noise in the case and the components won't be properly grounded. This guy knows his stuff. He's owned a power coating buisness for decades. Hes powercoated everything from car parts to military equipment. Is this a concern?

May someone also comment about painting your case with spray paint?
My father is one of those electrical-know-it-alls and I'm pretty sure he said something about ground when I was talking about painting my case.. I would love to know this.

Not like it would stop me from painting my case or anything.. hehe

He's local. The Powder Man in Sparks, NV. He's owned his buisness since 1979 and he's quite knlwedgable. But with all the powder coated cases I've seen people do it doesn't seem to be a problem.

There is no need to worry about RMI/EMI/grounding issues when powder coating or painting a case. I've painted several of mine (coupled with probably 1000's of people powder coating theirs), and there has never been any problems ever reported by anyone.

In fact, electically decoupling electronic devices inside of a chassis (if you could without the standoffs threads cutting through the powder coat) and grounding the case to earth ground, would form a rudimentary (not extremely effective) Faraday cage.

@Philistine- The only worries that you need to watch out for is that they plug threaded holes I had my case powder coated flat black and havent had any problems with grounding or electrical noise.

This.

You will have to retap your screw holes - but not a big deal for the quality look powdercoating gives. Other's more knowledgable then I have commented on the electrical concern already.
