Hello Experts,
I am working on a design that sends relatively high speed signals (10gbps) over 
microstrip (I know not the best choice, but it is a short run, and would 
require several design tradeoffs to run on an internal layer). It has been 
brought to my attention that we need to put some labeling on the board, and the 
only open area is right on top of these traces. I nixed the Idea of using a 
paper label there, but then they asked what if we screened the label on the 
board. I am not terribly excited about the idea, but as Eric loves to say you 
have to put in the numbers before you can get an answer. So the question is, 
does anyone know what the dielectric constant is of the ink that is used in 
screen printing? Is there some other reason why this is a terrible idea?

Thanks for the help,

Matt Severini
