[PCB_FORUM] Re: Is silkcreen affects the traces with impedance

Hi

The silkscreen will have little effect unless you have the silkscreen 
absolutely plastered over everything.  Even then it will not lower it very much 
at all.  Bits of text or lines will have no measurable effect.  Soldermask will 
most likely lower it more, by 1-2 ohms say (depending on the type of mask.)

Cheers,
Richard

Hi friends

I have a question here. Do you have any idea if the silkscreen on  top of
traces with impedance affects the impedance matching of that traces.

Marie.
