Hi Patrick I do not know very much about good second hand x-ray units but I have seen a very impressive BGA rework station (called fineplacer) on the Productronica '97 in Munich. It works with optical alignment prior to BGA assembly and has an impressive list of customers so far. The name of the company is Finetech Gesellschaft f. Elektronik-Technologie mbh and is siutated in Berlin/Germany. phone germany at 030-294 08 06, fax 030-294 08 06 Good luck, J?rg ############################################################## 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.
