Hi all, we have a Speedline Technologies ELEOCTROVERT/Aquastorm 200. In January we stared supplying it with pre-filterd to the DI cabinet next to machine so our large media would last longer. All was fine for about 4 months and then we started gett

Dear All, Is anyone know why too much solder paste might cause tombstoning defect? Thanks

Too much solder paste is NOT in our "Top Ten Causes of Tombstoning". Try: * Searching the fine SMTnet Archives for background * Looking here: http://www.efdsolder.com/PDF/EFD-Tombstone-Troubleshooting.pdf We have no relationship, nor receive benef

Dear Davef, Bill West, Thanks for your valuable inputs..Have a nice day.

The ONLY (unlikely) cause I could think of is if you are pushing the component into the solder, ending up with more solder on one side than the other. Why do you think it is the volume of solder that is causing this? By the way, there are "low tomb

I believe you hit the nail on the head. I just needed to hear it from another person. Glue is a good option. I'll give that a try.

Why do you want to increase the strength of the solder connection? Our experience shows that a proper solder connection has more strength than the strength of the pad to the laminate.

Yes, your strength of the joint is in the intermetallic, and not additional solder. Solder ain't like duct tape, where the more you put, the better it'll hold.

Let�s say I want to increase the shear strength of a solder joint. Does a lot of solder around a joint create more strength? Why not just absolutely bury the component lead in solder. My initial thought is that it doesn�t increase strength, but I don

The actual solder joint occurs BETWEEN the part and the pad. Adding more solder on top will add strength slightly, just by being in the way when you pull on it sideways. A weak joint with a weeks worth of solder on it will still be weak. Solder is
