Can some one provide information to rework ERICSSON bluetooth. How to remove and place the bluetooth mounted on the PCB? What type of equipment to use? Regards

James The machine will do it. If the machine calibration is questionable take the time and recalibrate it. Use local fiducials and place it as one of the last parts.

Hi everyone, I work in a development firm, that has a small prototype department. We have recently invested in a small automatic SMD pick&place machine. When mounting over 100 different components, the machine runs out of feedercapacity, and the res

You can measure temperatures any place that you would like, but the issue is the temperature of the solder. We've seen solder temperatures that vary from lead to lead on the same component. Why don't you want to measure the temperature of your so

We're used to placing the theromcouple on the solder joint and securing it with thermally-conductive UV adhesive. It's quick & easy to apply, and I've only seen a couple degrees difference from high-temp solder technique. Thoughts?

I've used Fuji for fairly large boards. The largest pcb size is 20" by 18" for pick and place; 18"x14" for chip shooters. I've never used Quad. N

Mike's comments are well taken. Your technique works fine with BGA, but uBGA are less forgiving. Again, let's take about: * Specifics of the problem. * Amount and method of applying flux. * What's holding the uBGA in-place before the solder ball an

Hi, thanks for your input. Yes, we do have a rework station - specifically a SRT Summitt 1000 station, but it causes us many problems and is down more than it's up...I do not think that using it would speed up the process at all. As far as accuracy

In regards to your last question, - problem is failures and most think it is due to too much flux - we apply flux with a brush - amount applied depends on the operator applying it - the flux is very thick and will hold the part in place before reflo

Has anyone caried out a DPM analysis on these components. I would be interested to know the defect rates and other assoc. placement issues as we have never placed them before. Thanks, cath
