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

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.

Hi Recently I have been set the task of increasing the amount of time our pick and place machines (Mirae MPS-1025P) are running for. I am fairly new to CEM and have found that the main reason the machines are offline for so long is that the operator

Dback, Some questions for you: 1. Are you using the red light configuration for better contrast on the 0402 parts? 2. Is your system fitted with both low and High Magnification cameras? Have you spoken with the guys at YESTech? Their phone support i

Thanks Reese. To be honest I don't know a great deal about the software just yet but we are running version 2.7.4. I know the guys are saying that they have a problem with identifying small capacitors and resistors as these have no markings though t

What version of sw are you running? There are some new features in 2.7.7 and earlier that may be of benefit to you. With chip caps you are testing for presense/absense. The gain/offset feature can be used to give you better contrast between the pa

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

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
