Since there are "no dumb questions": I need to properly designate a Cu-Mo-Cu material specification for a board that is 0.889 inch thick. This would yield 35.56 increments of 0.025mm. For the IPC-CF-152/5 CICWxS designation, should "x" be rounded to, say, 36 or left with the decimals ? Thank you kindly. ############################################################## 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.
