Helloo.. Steve, Not sure this thing gonna work for you or not, In my previous life, we used water-solube flux & paste and an in-line cleaner to wash off flux. For all touchup and rework, we used no-clean core solder and don't do any cleaning after that. No hand-cleaning of ws flux, Period. regards Matthew Park NII-Norsat International Inc. ################################################################ TechNet E-Mail Forum 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's web site (http://www.ipc.org) "On-Line Services" section for additional information.
