Have you tried to run the same process but with diffrent solder paste manufacturer.? This give you information whether paste is ok. Try also print paste on the bare board and run through reflow oven. Check 2-3 boards. Is it the same places where i

I am trying to use Mydata TM8C feeders that work fine on a TP93 running 1.6.18 TPsys but are not recognized by a TP94 machine running 1.4.7 TPsys. I get a green flashing light instead of a solid green. I can initialize the hardware but can not proc

Tony, search the archives for "hybrid profile". There's alot of good info. in there about running Lead-Free BGA's in a Lead process.

I assume you mean soldered and not welded. If the one pad that is having problems has a via hole next to it, it probably has more copper around it. Try running a hotter profile.

I believe you need 1.5.13 or higher if I'm not mistaken to run the mags with the button upgrade. There is no way around it that I am aware of.

First figure out which centering phase it is using when the part gets rejected. Then run the machine in step mode and watch whats going on.

Hi Tony, You should search the archives as there is a lot of threads on this topic. A couple of quick checks - 1 - Are you running a Leadfree Process ( if you are not Leadfree maybe the BGA is ? ) 2 - Check your reflow profile is hitting all the

Could be not enough peak temp. Do you have a profiler? I'd measure at the BGA joints- drill under board to get access to BGA solder joints and embed a couple of thermocouples with hi-temp solder, then run your profile to see max. temps. and that prof
