[SI-LIST] Re: Disadvantages of wider traces

It depends on the operational bit rates of the signals on that trace.
Wider traces do give lower skin losses, but dielectric losses will
increase and will eventually dominate at a given frequency for a given
material and trace width. Therefore at a bit rate (Gbps) adding trace
width will actually increase losses. =20

I also agree with Istvan with his comments on routing density and
crosstalk. With today's high pin count devices that aspect cannot be
ignored.=20

Subject: [SI-LIST] Disadvantages of wider traces

Hello,
Assuming that there is a chance for routing traces as wide as possible,
what are the disadvantages of having wider traces on the boards (>12mil)
in respect to noise, jitter etc?

-Thanks,
