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

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

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

Our AOI's are image based.

Is there any effect when using Water Soluble Flux as they tend to be thicker and darker after reflow. How does AOI machines react to this? regards,

I don't think there is anything releated to IR light in your false calls rate rise on Post-reflow. Soldering Flux is most probably the reason. Indeed, more or less soldering flux residue condenses on the boards according to the oven extraction syst

I am being told that boards that are "just out of the reflow oven" show more false calls than a board that has cooled down. Can anyone give me some insight on this ? Thanks, Sr.

I have noticed this on some of our large multi-circuit panels. It's such a slight rise in our false call rate that I haven't really explored it. I'm just guessing that it has something to do with the fiducials calculating the twist/shrink of the boar
