We used to batch clean RMA with one of the EC-7 family of solvents. I'm not sure what the rinse was made up of or if it was even anyhing other than DI water. We are now using Water Soluble for wave and reflow, RMA for hand soldering and cleaning all in an inline cleaner with Alpha 2110 and DI water. We did clean RMA from wave and reflow in this rig before going to WS.

Our current parameters are 155 F for wash chemistry for 9 Minutes, 100 F water rinse for total of 15 minutes, and 12 min. dry @ 120 F. We would like to hear from Techneters who are successfully using batch cleaners to remove RMA fluxes in terms of machine mfr., chemistry type, wash and rinse parameters. thanks in advance, Ken Devitt Tom Long [log in to unmask] [log in to unmask] 973-284-3880 973-284-2786 ################################################################ 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.
