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

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.

I don't know about that machine but 5000 wouldn't suprise me. And make sure your targets is less than X false fails with zero false passes. I can probably get zero false fails with any machine but I"m sure a lot of defects would get past that machi

Hi Nemo, In my factory we have an offline AOI from VISCOM for two SMT lines. It's not so easy to program, but the results are very good. Anyway you should have to think that an AOI system needs a human inspector and a technician to debug the program

We're a Tier 1 Automotive Supplier building, what I like to call, Peanut Butter and Jelly Boards. (High Volume, Low Complexity) Our first pass yield, using standard 1st Article Inspection and AOI is about 98-99% on any given day. Last night, for ex

Hi, Besides the 2 machines mentioned which are part comparison machines that require the operator to provide a pass/fail on each ref id, there is a system called the FA Inspector which offers the mode described above and two additional modes: 1. Au

Typically on my company's Mirtec systems, any anomalies, such as cracks, chips, etc. on chip capacitors and chip resistors are going to be detected with just a basic mounting inspector. We have a full image of the part (solder joint not included) as
