If you are using a well maintained chip shooter, you should not see more than 1%-2%, and that is on the high side. Most pick and place machines (depending on what they utilize) with laser, vision, mechanical centering will most likely reject a diffe

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

We've placed some crazy parts with Mydata but always used the mechanical centering jaws as the vision algorithm is lacking for pattern recognition. Could easily do a poker chip (or other circular things) in the X&Y but maybe the text wouldn't be str

Hi Joe, first of all thanks for your input. I did tried to search for the Mydata brochure and found that they are using Lifescan Vision System (LVS) which i think should be vision analysis. Appreciate if you can explain more in detail how's the mecha

Hi, What kind of Quadra do you need? We have a couple of mechanical centering quadras, one is in good working condition, the other one we use for spares. If you are interested we can offer them to you with A LOT of feeders and many other spare (n

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

The mechanical centering is used for testing resistors, caps, and other various components. It is also used to center parts by "tapping" them with a set of jaws. When the head picks up the component, it is between these jaws. Each part is setup to

+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

I agree avalancher. Your description is a valid point. But, I am still under the impression that the vac level is a separate issue. His original problem was 0402's missing off the board ,and weird measurements showing up when parts get rejected. I w
