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

It depends on what you're doing. Say for component placement verification, a line that's kicking-butt might have time to look at a somewhat different quarter of each board, depending on lots of stuff [eg, board, AOI equipment, line rate, etc.]

From the manufacturer's perspective, we aim to be able to fully inspect all components within the beat rate of the line and generally do. I'm not aware of any competitive machines that do the random sampling that is suggested above, however it is do

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

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

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

Prins: Everyone has equations. Here's one some people use: False call rate = [Number of defective boards, but good at inspection]/[Total number of boards produced] Why don't you ask the people [that calculated the numbers that confuse you] how the

how do i calculate false call rate? i got this equation = [over reject / (total solder joints + components) ] * 1000000 and i got a table which shows data like number of solder joints, components on panel, and number of false call, and the false

Does anyone have any experience with a table top AOI? If so, how would you rate vs other options? Thanks

Viscom S3088UltraBlue is a powerful machine and vVision software is modern and easy to use. Great algorithms and power for experienced users to generate custom inspection processes = low false call rates. Viscom been in AOI for 30Y, well made German
