Hi All, About to get into a discussion concerning ENIG PCB's, and solder joint appearance. I've used a 2% silver solder paste because from past history at other employers, it did seem to make a difference in the overall appearance, surface, and otherwise, for the better... But from my perspective, ENIG plated PCB joints, won't ever look like the joints on a HASL plated PCB. A 2% silver will make things look a little better (In my humble opinion), but they still won't be as bright and sparkly as a HASL joint will exhibit... But is that really a problem? I know what the J-STD-001, and the -610 says, but I'm about to face some concerns from one of our customers that the solder doesn't look as shiney as it should be ( I think)...bottomline, they have some concerns about the solder...the boards in question are ENIG... I know this has been talked about over and over again, and I used a 2% silver solder to try and make things look a little better. It does, but the joints still aren't as shiney as a HASL joint....they won't be as long as you have gold in the equation, but that doesn't mean that the joint is bad... Next week is gonna be fun... -Steve Gregory- --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d 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 delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL To recieve ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail 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 ---------------------------------------------------------------------------------
