Greetings All, I would like to know the best height for spacing 20 pin LCCCs off the board, and the best means of achieving this height. My concern is that there be some compliance to allow CTE mismatch between the part and the board during themal cycling. Any recommendations? Thanks, Bill ############################################################## 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.
