GOOD MORNING TECHNETTERS, Having been the initiator for this round of discussion on the above subject, and having been warned by at least one other TechNetter, I can truly say that I have been swamped with some very comprehensive info from many resources on this subject. However, even though I am still trying to sort out the best approach to proceed with, I would appreciate the opportunity to expand the context of my original question to include in the following aspect. What is the best cleaning solvent to use which satisfies the intent of my original question but relates more specifically to "bench top cleaning of assemblies after the soldering connections have been performed using RMA Kester 185 or 186 flux?" Recognizing that there is a wide spectrum of products to choose from I would like to known what the experts consider the best to use and why? I fully realize that this maybe a difficult absolute goal to achieve but nevertheless, the goal reminds me of the snail, who without perseverance would never have reached the ark. Have a great day, and best regards, Faz. ############################################################## 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.
