AOI false fail PPM

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

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

Can anybody know the acceptable PPM (part per million) on AOI machines on Low volume-high mix also on High volume-Low mix. We are a Low volume-high mix company, we have Agilent SJ50 Series 3 machines Can anybody have the idea how many PPM are good

With AOI it really depends on what you are testing. Not only what criteria, but what different types of components. We run a high volume low mix application for automotive checking for presense, positional accuracy, and all solder joints. We curre

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

Aren't you worried about false passes? With that low of false fails, you must be only inspecting easy stuff like presence and not checking for correct parts.

SMD PPM data

Hi All, I would like help in establishing what is a feasible PPM reject rate from a typical SMD line. As a reference an SMD line consists of, solder paste printer, chip component placement, pick and place IC components and reflow. What is a bench

Introducing AOI inline.

Currently, our AOI is performed after all solder processes. I think we would be better served incorporating AOI before reflow. Does anyone have supporting data like ppm or ROI?
