No arguments there. I 100% agree that quality engineers can and do solve a lot of problems on the spot. I've nevern said "run an analysis as soon as you get a problem". The whole nine yard started with a solderability problem. In my previous product

You missed my point. People often don't find the need to post their problems here to begin with because "knob turning" solved them *before* they needed to lean on the collective experience of SMTnet, Technet, or what-have-you. Your posts seem to b

Hi, I had similar problem a while back. Diagnosis was a combination of two things: 1 - Gold thickness was below spec. which gave us solderability problems. There should be other areas of the board that show signs of this. 2 - The devise in queast

And I bet you are not alone :-). All I'm trying to say is that there are problems which can be fixed by knob turning, but there are also others which can not. So, the appropriate analysis should be done to find the root cause and fix them. In the re

We can't help but wonder: * What are the measured temperatures on a good solder connection and the picture connection? * Why use use Type 4 solder paste?

I wish i saw at least one problem posted here being solved by the "knob turning" technique

Perhaps people are solving their problems by turning knobs and thus not finding the need to post here.
