Regarding placement of decaps

Can any one give information about different styles of placement of De-coupling capacitors. One of of my seniors want the capacitors to be placed diagonally. What are the advantages of placing decaps diagonally and what is its effect on Assembly. And also please suggest any site that gives more info about placement of components. It will help me very much as iam new to this PCB designing field. Thanks and regards, Kingshar

Diagonally?

Minimize the trace length connecting to the planes. Minimize the loop area between the 2 vias.

Hi KIngshar,

Yes, the question is "why diagonally?". Is the part these are decoupling rotated also? Not sure of the engineers reasoning.

Try UltraCAD.com Doug Brooks should have something there useful. (look under articles)
Also www.speedingedge.com Lee Ritchey probably has something too.

There's WAY LOTS! information online. Do a search on Yahoo for "bypass cap" or "decoupling capacitors", and begin your quest.

Good day.
Mitch
