Recent EDN Blog post on EMI and PCB layouts

tarribred61

Hi all,

 

I thought I'd pass on a link to a recent 3-piece blog on EDN about PCB layout and EMI from early March 2019.  This had good refresher information for those of us with experience and maybe some new info for the less experienced.  Where I work, it "sparked" interesting discussion about the speed of electrons in wires (actually very slow) versus the speed of the wavefront in the laminate (speed of light compensated by dielectric constant).

Cheers,
