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?

We like our AOI from Cyber Optics but only use it for process prove out. I would rather have a solder paste inspection system in line. The cost of AOI is killer. A new process is to embed a UV signature between the components pads and when a componen

Now I need to select a AOI machine. There is a problem. My company have a non-stop production process of different PCB. One manufacturing process can be 24 - 48 hours long ( about 2000 to 10000 PCB from different costumers) and so I need to find AOI

Your process makes a bigger difference. What I have seen is ICT done early is better than AOI done more than a half shift later, and AOI done early is better than ICT done more than a half shift later. For high mix/low volume, I would go with AOI whi

We're using a PFC (Product Flow Controller) box by Cogiscan between a conveyor and Agilent SJ-5000 (AOI) and the problem we're having is that when the downline smema cable is connected to the PFC box, the AOI conveyor belt keeps on turning even with

Omron is probably worst choice for AOI unless you have long series. Requires too much debug and there is always compromise between setting sharp criterias and get lot of fake errors or setting lose criterias and get boards with defects to pass OK. Y

Hello Diego, what kind of statistics you want to collect? From SPI, AOI, Pick and place maybe? Alexei is right, it a complex thing you wanna do. I would suggest doing it line by line in the beginning so you can better define what exactly you want or

And I might suggest AOI at post print and post place to hone your process before even considering post reflow AOI. Post reflow AOI alone is iffy and an absolute chore to keep up with. But monitoring paste and placement are very easy. Establish a sta

I have been using ICT for a number of years. It is still a viable resource for catching defects in the production process. AOI doesn't catch everything, such as bridging on QFN or J-lead devices (this will depend on the type of AOI and camera syste

I heard an interesting statement from someone the other day. "AOI machines are a tool that are put on the other end of a bad process." "Why not fix the process?" Interesting concept......eh ?
