Here is the IPC Standards Tree [ http://www.ipc.org/4.0_Knowledge/4.1_Standards/SpecTree.pdf ]. The design standards that you ask about are over on the right side. I'd guess that the following standards would be a good starting point: * IPC-2221, "

try Almit Sn62 HM1 RMA V14L ....its the best no clean lead paste for wetting...I sell it and it has solved wetting problems many times when users have used other pastes

Hi All, I�ve been doing some research on the issue of running lead-free solder paste and leaded solder paste through reflow at the same time. The point with this would be to process all standard leaded components with Lead paste while also processi

I am considering using high-temp ball Sn10Pb90 + eutectic solder paste for MLC reflow (no underfill). You can see that there is no Intermetallic bond for the paste and the balls. Under high stress/shock condition, the solder joints develop micro c

Is there any good articles to read on solder paste? (just to see if I may of missed something) Sometimes I can not believe the people I have to work with. We had a panel with two “Quad Flat Package” (QFP) one in each of the two circuits, almost fr

My customer wants an SnPb 63/37 BGA soldered using SAC305 solder paste. What data is avaiable showing the long term reliability of the intermetallics of the solder joints?

I am a big fan of AIM SnPb solder paste. I currently use NC257-2 (no-clean, 89.5%), and recommend you include it in your evaluations.

I have another idea. Would you check the apertures on the stencil? May be they didn't cut the right size apertures there. If you have smaller aperture you can't get the right amount of paste.
