Hi, It sounds like your vision is not setup right for this component, and it's rejecting some of them because they would be failing the test. This brings up a point we discovered. Don't use auto teach for the component if your using HYDRA or vision

The part I'm having problem with is a simple 0805 resistor 0R the inspection is done optical not mechanical and 75% of the rejects rate has the message: one or too many bad leads found. and the other 25% the messages will give a Background or Contras

Hi, There are a few different types of CP6 which I think the main differences are on the board loading side of things. To briefly answer your questions: 1.What is the actual CPH you are getting during production. There are a lot of variables to c

There is learning on all brands requiring fine tuning the test parameters. The first point is not to allow defects to escape. Many brands can do a good job with preventing escapes. The struggle with all the brands becomes false calls. The companies r

We have some problem with the Pb-free SOIC's at the UIC GSM2 on the Flexjet head camera; (seem to remember this from before, but I can't find it on this forum). The Pb-free small SOIC:s are reflecting the light differently than leaded parts and are

This type of component packages works best with vision type: 254 - irregular. Measure the total package length including the leads. Also set the body dimension x-y tolerances to at least 0.35mm and the the pick up x-y tolerences to 0.5mm in the part

Thanks Mika. I will have opportunity to check it out in New Year, because now we dont have production. So far we have beeen using vision type 11 and to be honest this type of defect, that placement of TNTA at flank side, happend very seldom. Usually

What about the component placement with Head #2? Head # 1 is ok? Is it only the pickup that is the problem and if so, from all feeder banks (front & Rear)? Concider Z-axis height adjustment, procedure is in the manual. You normally don't need to re-

Our UCT runs on windows. I like to use UPS then drop that program on the machine then save it to UCT after it's running well. I guess mostly because I'm used to UPS/uploading CAD data. However, if you use UPS in combo with UCT you must be sure to

Worked for MPM for many years, and this sounds like a fairly common problem which is easy to fix if you can answer a few questions, several of them already asked... 1. Is this happening only on this board (if the answer is yes, this is a good thing!
