we changed our top/bottom clamping system in the Printer, to a side-edge clamping system. This removed the higher paste issue similar to your thread.

As a starting point, consider that these component leads may not be getting hot enough. Measure the temperature profile on the leads that do not solder well to be sure: * Heating and cooling ramps are within the paste supplier's recommendations. * C

We had the same problem and solution with one of our components on one of our lines. Don't know for sure what the "weight" was that they used, but it did solve the problem. Since then the same line is looking a putting an adhesive on the part to ho

Has anyone ever placed and reflowed a 1.27mm PBGA to 6 mil poly flex bonded to aluminum? If so what is the life expectancy of the solder joints?

"Blank" means "bare board". Gray beards used this expression a lot. It has stuck in many companies, even after the old timers went to work on the BIG wave solder machine in the sky.

"We visually inspect and check solderability at incoming." Would you mind sharing how you are doing them? Is it really necessary to inspect visually using a microscope all or every PCB's delivered by the supplier? If not how will we check the qualit

Ok I fixed a couple of things in the search and now I get 7387 results for solder. I'm going to fix the "only searching in the forum" part next.
