uniform service esd Questions are: * Why do you "just to have to replace them in a short period of time?" * What do you mean by "a short period of time?" * How will that chage if you contract with a service company?

Not specific to QFP, but I had a run of poorly etched boards. I could see the short using 75X magnification with back lighting, but only some of the time. Nasty little shorts on ~25% of the boards that cost us a boat-load of cash.

Fresh production run? As in starting with BGAs opened from the previous run? And then using BGAs that have been never opened? Look at the balls where the shorts are. They are smaller. You have delamination. I suspect that you have moisture in yo

I think this part has terrible thermal balance. I assume in reflow process the part is bending so much that it will cause the shorts you see. I would suggest you get one of these beautiful hi temp cameras and record the reflow process. This video sho

Armin: Locating vias within the courtyard of components is bad practice. Concerns are: * Poor solder paste print quality, caused by the via preventing good stencil gasketing. * Poor component reflow, caused by the via holding the component out o
