Hello the world: I am looking for help from some of you who have experience of implementing SPC over the primary image process for fine line production (3mil/3mil). Could you share information about data you collect and the anlysis conducted for determining the process capability ? How many of you actually achieve reasonable yield without using liquid ink and collimated or point light source. Imput is really appreciated ! ############################################################## 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.
