As far as the large thermal gradient I have on my thick and thermal heavy board, I've done quite a bit to minimize the gradient but not successful. it's like one pad is connected to a signal while the other pad is connected to ground, you can't bring

try using thermal pads under the area without the balls. yeah, its a pain but we did it before for lot run of 500pcs BGA. Not feasible for mass production run, you say? well, thats why there's a thing called DMF, and why its the designer guys res

Some of the MPM machines have a SMEMA configuration in the software. Not sure about the UP500.

Yeah, it's set to use SMEMA for down line. I have the conveyor conected to downline fmi on up500 (right side of machine,) but the Upline Ready light is activated on the up500 when the conveyor is ready and not the downline like I would expect to see.

Would like to find out if the nozzles used with the Zevatech FS730 and FM740 component placers are repairable. In other words, is there a way to get around having to cough up $500.00 per nozzle when one gets damaged? Any insight would be greatly ap

I believe NEA still sells new UP500's for around $45K. I think MPM dumped them all there and pays them as they sell. Is it worth looking at if the software is upgraded? I had the general opinion that the hardware was not so hot.

Looks like I've got to reconfigure the fmi connections. Only pins 1 & 2 populated and when I jump the fownline pins the upline ready signal is activated. I'll reference the diagram and setup the connections for smema.
