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

Thanks Avalancher. I had no clue about the fact that Mydata could analyze part for me. Since I'm in montreal it's hard and expensive to get a Mydata guy up here but sending the parts down there would be an great inexpensive solution. I've been over t

In TPSys 2.2, you do not have the Auto Teach function that Grant was talking about. The thing to do at this point is to include a MYDATA person. They have services which offer you to send your problematic part in and they will analyze it and tell you

Are your rejections due to mechanical, electrical or hydra vision errors?

I just received a reel of RoHS parts but I have a rejection rate of 15% since I started using it.Does anyone has experience this so far? My machine Mydata My12 with TPsys 2.2.5e

Hmmm... that might work on some AOI machines but I believe the vision inspection is usually performed before the part is placed on the board, at least thats the way my machines work!! Website was much more attractive than moonman's though!!

Sounds like the vision is having trouble deciphering what is the component and what is the background. The problem is what if the plating is inconsistent (sounds like it is)? In this case with front (reflective) lighting the problem may never be so

Hi Red and Greg, First, to Avalancher, the service that is mentioned is fantastic. I have used it various times with various connectors and headers with fantastic results. Just contact MyData and they'll tell you what they need. It's usually 5-1

Try using a contrast filter. This seems to help. Also on the camera it self there is a white level control. Adjusting this may help. The bad thing is it may affect all your other profiles. Some times an easy fix is to have a screen print mark close t
