Thanks for the reply. I have not read that material. Having only started getting my hands dirty with PCB design a short time ago, I have much to learn. The whole EMC/EMI issue fascinates me, as does the design of high speed buses. So much information I've been hearing from people borders on conjecture, its good to hear from people that seem to know what they're talking about. -- Cina Hazegh ___________________________________________________ Cina Hazegh, Graduate Student University of California, Irvine -- Arts, Computation and Engineering chazegh@uci.edu | http://cinahazegh.com On Apr 9, 2006, at 4:01 AM, balloon-request@balloonboard.org wrote: > > > ---------------------------------------------------------------------- > > Message: 1 > Date: Sat, 8 Apr 2006 17:51:51 +0200 > From: juergen.messerer@freesurf.ch > Subject: AW: [Balloon] Questions about PCB layout issues > To: "Cina Hazegh" , balloon@balloonboard.org > Message-ID: <44157ADD0001382E@mta-fs-be-04.sunrise.ch> > Content-Type: text/plain; charset="ISO-8859-15" > > Hi Cina, > > Have you read the following stuff? > > http://alternatezone.com/electronics/files/PCBDesignTutorialRevA.pdf > http://www.fordemc.com/docs/download/EMC%20Design%20Guide%20for% > 20PCB.pdf > > Various Documents and arcticles can be found here: > http://www.hottconsultants.com/ > http.//www.ultracad.com > > I would suggest the following books: > PCB Design for Real-World EMI Control (Bruce R.
