Todd, I am unaware why you are clearly irritated with me. I am just trying to help you and anyone else that I feel I have information or ideas that could be of use, if my ideas are not useful to you please ignore them. You are clearly unaware of my

Guys, Everyone who posts here works for a company. I get emails occaisionally from people who are not pleased with the way the forum is progressing lately. If someone has a problem and a person offers solutions why is that bad? If an answer is p

Hi Greg. FujiCam has two ways of calculating the placement coordinate for a component. - The "FujiCam/Unicam way": calculating component origo as the center of the designed component pads. - Use the PCB designers part origo which could be center of

Francois, thank you very much for your recommendation twice. Is it any harmful for my evaluation? The component will go thro the reflow after drying process and not just only check the weight. The evaluation will go thro the C-SAM as Dr. Shook doc

Steve, I'd second Daan's opinion. BGA profile we use gets a peak of 210deg-C to 223deg-C (but that's using our WS paste unique characteristics) with reflow zone holding time of 45-60sec. We had 6 PBGA and 2 ceramic BGA on a 6 layer PCB. typical p

For us, no. Pain in the butt, yes. Volume build shops do not have the inherent flexibility that quick turn shops have built into their systems to deal with these problems. I�d speculate that this issue will help LARGE contract shops to rethink the

Claude, your not a manager by any chance are you?... you can't charge them for breaking them. Ok so yes there will be poor handling but if your going to fix the problem you have to look at teh route cause of it and fix that. You should be settign up

I've attended the Advanced Programming Course and the Maintenance Course at their Rowley, MA site. I also talked to the trainer, Toby Upham, about some of the other training courses they provide. It sounds like the New User Training course covers m

Individual process steps are approximately the same length of time for reworking a BGA. You seem to be comparing the use of the automated SMT line versus an off line rework station. Consider that the off line station is a complete paste print, pick

Not as such. Generally, people tailor their profiles to produce glam solder connections on their boards. Search the fine SMTnet Archives for discussion on the factors affecting solder reflow recipes. What is the best way to get these PCB made to s
