Dear TechNetters, It seems that the 'oxide alternatives' all have a problem processing rolled copper (RA), as e.g. used fore some flex constructions. Due to the different structure, there is hardly any coloring, and the surface structure must also be quite different. Does this mean we are stuck with the oxides?. If not, what alternatives are available.? That is, apart from doing nothing. regards Torben Østeraa Printca AS ############################################################## 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.
