PizzaFred, Scott mentioned lots of good ideas. Take one of your boards to each vendor and see what it takes to program the board how long it takes for it to become online. I've found some that are easy to program, but require 40 or more assemblies to

In the past year I was responsible for developing and leading a Team focused on AOI, Evaluation, Justification, and with a full ROI required, supporting a HMLV manufacturing environment. If you have in these economic times the additional resources t

Good Morning Roger, The Mirtec's can be adjusted to lower your false call rate. This can be done by reducing the matching percentage for each componnent but the result of this action is that the machine becomes less selective. If you lower them too

If you are in the Americas, I'd contact tech support and they should square you away on that high false call rate problem. They have great WebEx training and troubleshooting. www.mirtecusa.com

Board fabricators commonly use Barco AOI to inspect film. The AccuMatch compares pixel-to-pixel of the Gerber data to the image seen by the AOI camera. It's slower than design rule checking, but has definite advantages [like lower falsing]. Unfortu

330 000ppm on low volume. what is the parameter you are talking about? PPM on AOI?

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

PPM on AOI, this is our metric for false fail on AOI machines. Our target is 1000 ppm but I'm not sure about this target for low volume. (1,000 false fails on 1000,000 of inspections) thanks

Anyone else? This is an interresting question. With 1000PPM won't your AOI be worse then the process it is supposed to measure? Won't your AOI become more of a bling thing to impress customers than an actual usefull tool to improve process quality

We are in the process of determine our target. We are inspecting with all the options Presence, Joints, OCV, Polarity, etc. What would be an average of ppm on AOI? 1000, 5000, 10000? Low volume - High mix. our machines are Agilent SJ50 Series 3
