Dear Norm, I saw the article you posted on the IPC TechNet forum and I'm very interested with it. Is that possible you could share more details of your experiment with me? I have a customer who asked me to give them a number of how many times of insertion the 30 micro inch electroplated edge connector could take before any problem being raised? When you say 50~75 insertions, what exactly does that mean? Does it mean the gold plating will be gone and Nickle be exposed? Or it would malfunction? Or it's for high reliability maintained?!! Your opinion and information is highly appreciated. Many thanks!! YH Shiau ps: Do you know similar experiments being performed by others?? --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
