Fifth, if an individual component is off, but all others are on, * Go back to the CAD file and find out why the centroid is not correct, and fix it there * Check the feeder calibration, In short, you should never "tweak" your pick and place machin

Ditto for what most people have said. If you have good equipment/ good data / 3 or more fiducals..everything should be OK. Maybe dirt or something got bang'd. tweaking is evil,but if nothing else works??? dave

I used to love tweaking. I tweaked and tweaked until I got a master degree in tweaking. But than I had to teach others how to program a board and avoid tweaking. After all it does not go quite conform with ISO and other quality approaches. I investig

In theory, no tweaking is necessary. Unless you happen to work with equipment old enough to vote! We have several lines with old MK chip shooters. of course, we use the same program for all the lines. There is no way to calibrate each machine so that

When only a few components are off placement? You'd like to say no tweaking of any kind, anywhere, by anybody (but me). But you're not there to run to their rescue all hours of the day and nite (almost but not quite), and getting product out the do

Ahhhh America.... It is great to agree to disagree.

Does anything happen when you tweak the magnification/zoom settings?

I disagree on the dirty glass scale offset theory. If you have a dirt spot on the scale, every time the axis comes over the spot it misses counts. After a few movements it will not find the components in the feeder anymore, because the failure adds u

I would be willing to bet that you are ramping up way too fast and possibly too hot/long of a soak and killing your flux activity. this will give the appearance of "no reflow" due to non-coalescence of the solder balls. check this board with the hel

At my previous job I inherited several lines where tweaking of a few components was allowed. The first thing I did was stop that practice. The problem with tweaking a program is that you are fixing the symptom and not the root cause. When the root
