Dear Ashok, My practice is that if you see it as a source of a potential problem, label and monitor/measure/test it. OK, so it may be a lot of work up-front, but what is the risk involved in not doing it ?? There is no grey area, do all or nothing

Problems with dry joints on a 184 pin Berg connector with locating pins.Using a 0.005"screen, on a n-tek finished board and using Nitrogen. The problem is really intermittent.We tryed using a variety of placement forces using our siemens F5. The comp

Sal: JAX makes good points, but I�d like to think about this differently. It sounds like the poorly soldered connection is lifting the whole connector, so that termination floats on top of the solder, rather than submit to the wetting force and be

Hello Travis I'm going to have to disagree with your evaluation of intrusive reflow. It's not just for low end and,if done correctly, you will not have lots of half soldered leads and touch up will be minimal if at all. I'm sure that others will ag

I have not done pin in paste in production quantites, but speculation is always a blast so; OA fluxes are active at room temperature, they grow 'fur' with humidity if not washed off, great stuff for soldering, nasty stuff for reliability (if not rem
