Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar

OK, if the sphere of the ball and the paste on the pad are both eutectic, 63/37 then the paste will reflow first causing a drop of the component, after which the spheres will reflow causing a double drop and a good intermettalic. You can see this by

For what you have right now I would recommend that you use soldering iron tips that are made for component removal. until you get BGAs I wouldn't worry a whole lot about the expensive rework equipment. I would use specialty tips and a heat gun wit

A simple trick I read either here or on another P&P forum is to use "Silly Putty". Place a small thin spot of Silly Putty on the top of the front conveyor rail, and put the machine in "manual" mode. Steer head #1 over the putty and lower it, leavin

Thank you, that works perfect!! Now I was able to set up the offset's and program the machine, but now head #1 will move to the feeder location but it will not move down to pick up the part, then it moves to the drop area, but its only happening on h

Does nozzle #1 lower at all when it should pick up a part or is it just staying in the fully up position? If it does come down, but not quite far enough to contact the part, there are adjusting nuts on top of the head that set the lower limit for no
