Ed, My lab can do impedance testing of impedance coupons. I can be reached at 508-467-3109 or at [log in to unmask] Paul Terranova DIGITAL's Analytical and Environmental Test Services Lab Marlboro, MA --------------------------------------------------------------------------- From: NAME: Ed Cosper <[log in to unmask]@PMDF@INTERNET> A few weeks ago I asked for information on outside sources that do impedance testing of bare circuit boards. I received several references but I have since misplaced them. Would someone please provide those references again? Thank You, Ed Cosper *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * ***************************************************************************
