We have My12 machines. The precision is 25mic. There is no problem with the accuracy. I assembled components 0201, QFN 20mils pitch /12 mils aperture, 0402 flip chips. Even if you have troubles with the video codes definition, mechanical centering co

Hi, If you mechanically center, then you cannot use the HYDRA head, so you only place one 0201 at a time. That's not a great solution, so you need the MYDATA to be stable with vision. I think whichever machine has better vision would be the choice.

Calibration was done improperly or you have a bent mount tool.

Hello, I have some troubles with my MyData TP11-UFP with the precision of the placement. All the parts which are mechanically centered are slightly misaligned. Attached are some pictures of 0603 and a SOT23 part. I have made the calibration but it

Hello, I have fixed the issues with the centering. Below the centering head there is a adjustment screw. First you have to remote a few screws to get access to it. They you can turn the adjustment screw to align the centering jaws.

+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

Hi Folks, I'm working on a LED display that is composed of multiple layers. What is interesting for the point of this discussion is the PCB layer and the light deflector layer on top of it. Please take a look at the related pictures at http://plus

Good question :) I'd say with a machine that is available for an average pick and place operator nowadays. Our manufacturer is not fixed yet, that's why I don't have any specific. On a related note I'm wondering whether the machine is so importan

I would expect any half decent machine to place 0603 parts slap bang on target to the typical defined accuracy for such parts on most machines of perhaps ~60 microns or better. Self correction during reflow is IMHO much less pronounced with lead-free
