Is this a new problem on an old product, or is this a first run? If this is a new problem on an old product, you may want to check the paste process. If the paste is not even across both pads or is offset a bit, the parts will pop up. If this is a f

Dave and Russ, Today we modified the profile to ramp up slowly and have longer preheat time. The result is great, 0 out of 5 without bridging. I did review the FAB design and seen the pad is much biger than ball size. So I guess it is the problem.

Thanks, guys. The solder paste we are using is a kind of prototype from Alpha Metal - more aggressive, long floor life, etc. The paste I used to solder PBGA was out of fridge for about 3 weeks. It was still good for our other Non-BGA products. Be

Does anyone know how the Fuji IP2 can be adapted to place BGA's? The MTU places the chip on a carrier with suction in the center and it will not hold on to the BGA due to the lack of a flat surface on the bottom. I have had limited success building

Greetings, Could somebody recommend a good parts counter that can handle taped SMT and thru-hole components? I'm looking at some counters made by APS and some made by Grip, but I'd like some feedback about these products from people who use them. A

Slim KIC would be my choice out of these two vendors. I have worked with several different makes and models and I would say DataPaq was my favorite. But it all depends on your needs and budget. They can all get the job done. Good luck with your
