As the face of business changes through revolutionary factors, such as the increasing rate of outsourcing, manufacturers (especially EMS plants) will strive to fine tune their test strategies to ultimately improve and sustain product quality and to r

I can only speak for Mirtec and Yestech AOI for SMT Solder Inspection. We do use Koh-Young AOI for Solder Paste Inspection. As usual ,you need to identify exactly what it is you are trying to achieve with your AOI, if you are just trying to fill a

We are trying to implement AOI into the mix. One PE wants it Pre-Reflow, to catch and fix the PnP screw ups and the other PE wants it Post-Reflow, because the oven will fix quite a bit of placement offsets and mainly to catch any problems that the R

In a past life I ran F1 systems post placement / pre reflow behind a MyData My12E, so it didn't exactly have to keep up with a speedy chip shooter, but it did pretty well. The AOI would end up being the bottle neck some of the time, but not because

I agree with the stand alone option. That way you can sample PCB's from different stages ( print, placement post reflow) In a controled process, after reflow inspection would be ideal.

Hello Sibbe, Thank you for posting your questions. There are a few approaches to AOI with the majority being program driven. There are a couple of systems that are simply comparative in that you use the system to compare a golden board to others th

When you look at the capabilities of Combo machines they tend to sacrifice performance when compared to separate X-ray and AOI machines, meaning they don't do either the X-ray or AOI operations as well as a machine that was designed to do only one. A

About 2 years ago our company tried to go with a post reflow AOI inspection. This AOI was suppose to be able to inspect to a level class 3 product. **It is impossible** You cannot inspect for a heel fillet and inspecting for poor wetting is a very

The programming time depends on the system you are using. I use YesTech. It has been a reliable system for catching the majority of production issues. The programming time on this system is around 20-30 min. with a full library, meaning you don't

Thanks for the clarification, I have worked with both application, especially pre reflow. The data you should consider collecting pre reflow is missing, skew degrees, x,y shift, bill boarding, polarity and match the failure data (ref. desg.) to feed
