Our company is having issues with our YesTech F1 AOI machine the programs are currently not utilizing this machine correctly. we are have a false call rates of about 5% to as high as 12% of the total number of inspection points. I have started to rep

Hi All, I've been told that 3D AOI machines are a solution to the false calls that you get on a 2D machine, but I don't really see how the depth information can help in eliminating false calls for unreadable markings, misregistered parts etc. For s

We currently have 2 M1 systems. Our false call rate has never been has high as you suggest. There is something wrong with your program and/or inspection algorithms, as you probably already know. You should be somewhere between 1000-1500 vcpmo (fal

SMT, I currently work with both 2D and 3D AOI machines. 3D does give you the added benefit of Height on components which does help cut down on some of the over rejects. However, it does still have trouble with some of the same things as the 2D system

Hey Reese what is your Mis rate? Do you have any boards that are passed that have actual defects?

That's hard to quantify. I deal with escapes when they occur, but I haven't kept track of that data. It doesn't happen to often. But when it does, I take it back to the AOI to analyze why it escaped, and change the algorithm to catch it, if I can.

Hello, that's why some machines still use 2d for most of their algorithms and checks. They use the 3D on some special cases (like lifted leads). The full 3D machines are for me more complicated, because you can't use some simple 2d checks where appli

Programming is different, yes, but so is the terminology. ///with machine vision you have parameters that select what is good and what is bad, and you have parameters that help make bad look worse and good look better making the difference between w
