First all, you must define the specific defects that you wanted to screen out by your AOI system based on its capability, so you can allocate the undetected defects on your other means of inspection methodology. Then optimize your AOI inspection para

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

You don't say what inspection type generates the most false failures. Each type has its own remedy. We see a lot of solder false failures on components near the edge of the inspection window. Creating a new frame for that component often clears th

The CAD data is the centroid data, x,y location. I developed an Excel macro in which we import the data as a text file and convert it to the CR Technology format. Rates for false failures varies, but is ~10 - 20%. The operators are given an oportuni

Steve, When you say "CAD input", do you mean centroid data ( xy locations ) or generic cad info straight from the layout software. ( so far the machines I have been looking at use centroid) What are your rates of "false failures" and how do your o

I have worked with Radial II's, III's, and V's. Every one had a verifier, but none of them ever got used, primarily because of the false failures.

Paul, do you have any kind of false failure data for the application you struggled with? Also what amount of manpower did you use to operate the system(s).

I had a few questions if anyone is using this machine. We will have one in soon to try out. Does the machine pick up defects well or does it give a lot of false failures and pass up actual defects? How difficult is it to setup a reliable program? Tha

I understand the want to save money, but the new software is miles ahead of the old. You'll save the money quickly with reduced false failures and pickups, allowing to ID process issues much quicker.

jdengler, Thanks for the feedback! Based on your experience, it appears that our concerns about false failures and programming are definitely valid.
