Re: Patent: Shield Can for High Q Coil


 

Cool-Amp is easier than electroplating ... but if you're up for
electroplating, it's not too difficult and you can just leave the
copper coil in the "soup" until you think the plating is thick enough.
You're right, the thickness of Cool-Amp is more cosmetic than
skin-effect thick.

You may want to try Cool-Amp, but it's awfully expensive.

You have to ask the question, how the thickness of that plating compares the the skin thickness.
At 1 MHz, skin thickness is 0.0025". I don't have any guess for the thickness of that plating,
but I don't thing it is near 0.0025".
I wonder if you can put more than one layer on or if the bond is only copper to silver and not silver to silver.
