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?

"When we solving a problem we have to be absolutely sure it's really solved." Conversely, it's always good to return things back to the way they were when you conclude that THAT knob turn didn't solve the problem.

May be you right, but I spend a lot of time on Technet (a similar site maintained by IPC) and people who posted questions usually come back saying whether the problem has been solved, as someone else may face a similar problem down the road. I think

hello guys ; we are using a fine pitch component(0.65mm) on a thick copper PCB (Cu = 90�m) ; in this case we notice that we are in the process'limits , because the different supplier of the PCB are not able to ensure a good stability of it's process

If you are certain that reflow process is good, I would suggest starting checking the following: 1. Check to see if leads / pads are contaminated or oxidized. However, this usually results poor solder quality throughout the board. 2. Check the amou

In the real world where I work, I turn knobs (really key boards, mouse, or touch screens) every day to solve solder related problems. I can tell you exactly why I have to for each one I adjust.
