funding from who?. we are dealing with the same thing here. the solder paste cost is roughly 1.5 times SnPb, and the cost of bar solder is thru the roof

All I can say about Alpha and their GOTT-DAMN website is THEY SUCK!! I refuse to register to view product literature... for that reason, Alpha Metals, you won't be looked at for my pb-free paste or bar solder evals.

Has anyone tracked solder (Paste and or Bar) over the last 5 years. My company would like to see what the trend was, but we didn't keep records since we purchase from distributors.

Questions are: * What is the scale and scope of the problem? * What does the unfilled portion of the barrel look like? * What class of flux is your solder paste?

We are looking for supplier of Sn60/Pb40 alloy (solder paste, cored wire, bar solder). Does some one have experiment on this?. Pls. advise.. Thank you..

did you look at the pad vs the stencil design? are you putting down enough solder paste on the pads? what are your reduction ratios for these packages?

If you are using SMT machine for component placement you may check your nozzle where in some cases solder paste stuck to it and during placement will easily get into gold pad area. otherwise you have use kapton tape in order not to expose those pads.

Is the hole always in the same solder joint? What parts do you see the hole(s) on? Can you try a different paste?

Lets not forget Chemistries... Pastes, flux, solder, glue, underfil, Mask. Someone with manufacturing experience. Cant forget Soldering irons and rework oh oh...and an X-ray.

Two lines of thought are: * That you have some solder connections points us towards components. It seems like the solderability protection on some components need to have the reflothermal recipe tailored for that component. * Paste selection is a BI
