We are looking at adding to our current batch washer (Older Aqueous Tech unit) and I am interested in hearing some thoughts as well as first hand experience on how the following two cleaning systems work with regards to low profile (BGA's etc.) devices run as both conventional and lead-free processes. We are currently running water soluble flux and are not using saponifiers for the cleaning process. I have listed the two machines we are considering along with my thoughts. I am interested in hearing yours. Aqueous SMT1000 - dish washer style loading, poor loading = poor cleaning - vertical loading improves throughput - high pressure pumps 120psi wash, 45psi rinse for leadfree but can this style of machine effectively clean under BGA devices? Electrovert Aquajet - large cleaning area (30x30") but horizontal loading would appear to limit throughput. - Is any racking available for this machine to process boards vertically for increased throughput (within height limitations of front opening) or does design technology reduce cleaning cycle when compared to Aqueous machine thereby somewhat offsetting loading capacity. - wash and rinse technology coupled with horizontal loading seems that it would do a significantly better job on cleaning under low profile devices Regards, John Parsons --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
