All I can say is my regular "Get it analyzed", so you'll know what the streak is. Regards, Vladimir

We don't know dip about your Linear Tech LGA118, but we agree with published reports that say you should have between 4800 and 7000 thou^3 of paste on the pad for a LGA. These volumes were analyzed based on volumes found successful for CGA and then e

Does the established joint still exist if once again re-touched by a soldering iron, or does it return to the original problem? Wetting issues on pad could be for many reasons and you could analyze with a cause effect diagram.

You have a board fabrication defect. Search the web for "hole wall pullaway" Performing a microsection is the best way to analyze the defect.

A few years ago we sent some samples to Dage for them to analyze on one of their 3D systems.

That's hard to quantify. I deal with escapes when they occur, but I haven't kept track of that data. It doesn't happen to often. But when it does, I take it back to the AOI to analyze why it escaped, and change the algorithm to catch it, if I can.

Ideally first you need to analyze the residue to see what it is. We had a customer with white residues after wave and elemental analysis revealed tin.

We resolved this issue a few weeks ago. It was a configuration mismatch in the oven (MR933+)software with the onboard O2 analyzer.

It shouldn't be any issue if you measure the top reflow settings using bottom profile board & the results are OK. To common the reflow profile, both bottom & top profile measurement are taken & analyzed. This, too, can be applied, even for differen
