You may want to look at which spindle that is dropping the nozzle and check the O-ring on the spindle head. It's probably bad, cracked, or broken. Replace it and that will fix it

Please search the archives as this has been discussed on many occasions. Everything should be fine except for BGAs which will require a higher temp of 235C at the peak in reflow.

we do it all the time. We havent had any problems with the BGA's. But, you dont want BGA right beneath another BGA.

We'd guess that you want the ESD ground at the same point as the building ground for personnel safety reasons. Injured employees and OSHA inspector should be enough to convice the old timers [in most plants].

I would suggest 1) Use the profile that is suggested with the BGA types you are using or 2) Have you solder paste rep visit for a half day and help profile your machine. Remember if they want to keep you as a paste customer they will help. Enjoy,

You may want to try reducing the large center aperture on your stencil to 50-70% of the area of the pad. This is what we do with QFNs and it may be applicable in this case also.

Hi Grant, We used to use Quicher automatic screw feeders - that basically present the screw for pick up to the driver - they worked very well. Let me know if you want any further info on this type of feeder as they may still be kicking around her
