Hi, Mike, I have no experience selling OSP assemblies to the Military, because we rejected OSP as a finish for such Class 3 boards. Rejection was on the grounds that it didn't survive double reflow well. I don't think exposed copper is quite the issue it once was for some reason, especially if the boards are conformally coated. I think sharp points like cropped connector pins are still supposed to be over-soldered so that they don't puncture a coating, but otherwise exposed copper is OK. Check out IPC-A-610 for acceptability.

Does anyone out there have experience with OSP and IPC class 3 products? We have considered changing over to OSP as things shift to lead free. We also see a cost savings in converting. However, some of our quality people do not believe the exposed copper on the edges of the pads is acceptable. I see nothing in the J-STD-001 or IPC-610 that says the fillet must cover the entire pad. Can anyone relate their experience selling OSP assemblies to the military? Thanks for your replies. -Mike McGee --------------------------------------------------- Technet Mail List provided as a free 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/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ----------------------------------------------------- [This e-mail is confidential and may also be privileged.
