Then your profile is way off. You need a t-couple mounted under the BGA on one of the center balls to measure correctly.

Its been my experience that a "dot" of glue on the center of the part is needed for "barrel" type components.

Might want to check to see if the weight of your part has increased. If it has increased, you may not have enough surface tension to hold the part on the board. I am assuming you already checked that the component isn't getting hit by something in

Could it be possible in my Quad 4c, to increase component size tolerance to reduce the rejection of components? Could this have an impact in the event of the machine picking a component off center? As in if the machine picks a compnent off center but

I've been using metal blades on several brands of printers over the past few years and have to agree with comments in other replies. Contact print is a must or you will tear slits in your stencils at the ends of the blade. Center-mounted (floating) s

Dude - check the centering jaws as well. If they're off a bit it'll do this as well. Is it just mechanically centered parts, or optically centered parts also?

The problem is that if we disable center head and even turn off the cable of center head encoder, it's not helps. The same error appears. And it's all the same it shows error of the center head.

+1 to what Sr. Tech said. I'd also add that you could have some uneven deterioration of the centering jaws. Check by doing a couple of things (this will help check if the tool/tip is bent/deteriorated as well): 1. Turn off mechanical centering, and

Usually the reason it will fail a part like that when you are using mechanical centering is because the part is usually picked so off center because of the body shape. So when the centering jaws close to push the part to center they give up and fail

Feeder calibration helps to center the window opening used during component pick-up by a machine nozzle. Once this is established, the next step would be to confirm the centering of Machine nozzle to the center of this feeder window during machine op
