Scott I think you read that someone WANTED the specs to change based on a report done by ITRI. HOWEVER if you review a couple of the replys to that notice pointed out that the tests performed by ITRI were not the ones considered to have the greatest impact on inner layer reliability. The tests performed were the ones that test the barrel plating and therefore the results obtained by ITRI were an assessment of the robustness of the electrolytic plating and not a measure of the impact of mis- registration. I am certain that this topic will be discussed in depth at the 6012 mtg at DC next week Susan Mansilla Robisan Laboratory ############################################################## TechNet Mail List 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 web site (http://www.ipc.org/html/forum.htm) for additional information.
