Finding Power/Ground Defects on Connectors - A New Approach
adcontent.reedbusiness.com/chipzlinks/Finding Connector Opens 20070613b-for-TMW-Aug-2008.pdf
Printed circuit boards are steadily becoming faster, and as a result, relatively ordinary defects in connectors and sockets can now have more subtle and damaging effects. At the same time these defects defy detection by conventional technologies. This paper surveys existing tests for these defects and introduces a new solution based on Network Parameter Measurements.

    Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
