Fellow technets, We are in the process of selecting a new saponifier for our in-line cleaner and developing the accept/reject criteria for the selection. We mainly use RMA fluxes on densely populated, double sided smt boards with various BGAs. The typical visual and ionic contamination tests (using an Omegameter) will be run using test boards, and we would consider other tests as required such as having a lab perform a SIR test. Some suppliers of saponifiers have offered to run cleanliness test as part of the evaluation process. Would anyone like to comment on: * What types of tests should be run to determine the cleanliness of a populated board when evaluating different saponifiers? * What IPC spec defines the SIR requirements and methodology? What are the benefits of running a SIR type of test as far as cleanliness goes? Look forward to your inputs. thanks again joe --------------------------------------------------- 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 -----------------------------------------------------
