FreeLists / si-list / [SI-LIST] placement of added capacitors during troubleshooting

[Doug Smith <doug@xxxxxxxxxx>]

Hi All,

I have posted my latest "Technical Tidbit" at http://emcesd.com. The 
title is: Placement of Parallel Capacitors on a Printed Wiring Board
(for troubleshooting or a quick fix)

Abstract: Capacitors are sometimes added in parallel to an existing 
capacitor on a printed wiring board to improve the high frequency 
characteristics of the existing capacitor for troubleshooting purposes 
or for a temporary fix. Ways of mounting the added capacitor are 
discussed and recommendations made. The most popular mounting method 
is shown to be ineffective for some cases, especially at frequencies 
of hundreds of megahertz and higher.

The link to the article is the picture at the bottom of the home page 
at http://emcesd.com of the board with one part stacked on top of the 
original capacitor.

One of the purposes of the articles I write is to give engineers a 
source to cite to peers or their managers to support the engineer's 
views. Having an independently written article that agrees with your 
position can be a powerful tool to advance your views in the 
organization. If the "Technical Tidbit" articles have worked for 
anyone this way, I would be interested to know.
