| | | Your problem may be related to silver migration (leaching) into the solder. I had what seems to be a similar problem. The solution was using solder with 2% silver content. See these pages for a bit more information: | | | | http://www.ferr

Starting with the manufacturers layout is a good start. Tilted parts, bad solder joints, sounds like a wetting issue and the board or the parts. Insufficient solder sounds like the printing process needs some attention. We have used this part in th

Dear All: We have a problem of soldering big BGA's (3.5Cm * 3.5 Cm)during rework or repair. With three big companies stations (hot air & infrared) with their support, they faild to re-solder even one BGA succesfully. Note that we workes on a good te

Another basic soldering question. I notice that lead-free solders have become required for plumbing applications due to legislation. In a local hardware store, I noticed the existence of lead-free solders (based upon tin-copper I think) with a melt

There's a lot of sources of solder balls. Search the fine SMTnet Archives for previous discussions.

We are in the process of researching and gathering information on establishing a zero-defect soldering program. I am sending for an IPC video on the subject. I am particularly interested in getting some direction and hearing from those of you in the

Joseph, I've heard of a lead free solder alloy, Sn43/Bi57 that melts at 139�C and reflows between 160-170�C. You may find the following website useful. Good Luck Scott
