One wood agree the offset you are seeing is enormous and probably PCB tooling related. However, if this is ruled out you should have the C-tool to verify your cube alignment. Who knows, maybe your cubes are loose?

All, What controls do you have in place for PCB moisture control? If you had a kit of 400 and you ran out of a part which wasnot due in until 6 weeks- do you store the boards in a dry cabinet ? Vacuum seal and store on a rack? Alan...

I've cut component patterns out of old stencils. Not as good as buying a new mini stencil but still it worked. I guess you can't buy those pre-pasted boards? I've never tried them but they look interesting.

SAC solder balls reflow with Sn/Pb paste - Voids Issue

MELF's falling off

Electronics Forum | Tue Oct 17 15:31:29 EDT 2006 | TM

I've got some MELF packages that reflow and connect but later fall out of the solder pretty easily. We are not using epoxy but, the parts have fillets per IPC standards. We have not looked at cross-sectioning for IMC and don't plan to at the moment
