I'm trying to evaluate the impact of nickel plating (under gold) on RF boards. The archives have some postings from 3 years (or more) ago, but nothing quantitative. Can anybody share the latest results/opinions or point me in the direction of any good sources for information about the effect of surface finish (nickel) on electrical performance (loss) on RF boards? Thanks. ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
