The big thing to worry about is the change in impedance when you go from
tight to loose or the reverse. Any good 2D field solver will allow you to
quantify that.

Subject: [SI-LIST] Loose coupling vs tight at the same time
Hi,
We’re having a discussion here and I would like to know your thought about
it.
How bad is it to transition from tight coupling diff signal to loose
coupling signal and vice-versa. We have a case here where we pass-thru a pin
field and we reduce the coupling from loose to tight for 2”and get back to
loose after.
I’m not sure that it’s a good approach. What’s your idea on this?
