Hi all, Having a major problem with an IC being placed upside down. We pick up the fault at AOI. We have check several reels and the component is not placed upside down by the supplier. Where should I start looking; 1. Are we using an incorrect fee

A configuration of a number of AOI tools located at different inspection stages along the SMT production line has, by its nature, the ability to provide a faster and closer response to possible process related fault occurrences. Comparing with today

Thank you for kindness advice. From the result of IC after pass the reflow process. The color of letter will change to similar color of material compound of IC. Then when we inspection by AOI machine, we have many problem about high fault reject rate

Teradyne says, "How does one evaluate the competency of a particular AOI system? At the highest level, all potential customers must judge any viable AOI system using the following qualities: * Throughput must be able to match the line rate on the man

We are already using ICT on the PCB, which should catch most missing components, also components installed backwards, or the wrong value(to a point - we do RF so we have lots of very small value caps and inductors which can't be measured), and in som

Every time to create new AOI program we must manual set at bright lighting level for each component. then this case we think the parameter of AOI setting it not concern for this problem due to the golden board that we use to confirm machine before st

An ultimate truth in AOI is that "you can not avoid what you can not see". At the post solder stage, 2D inspection is typically not enough as it simply "can not see" everything using a single perspective, and therefore, can not detect all of the faul

we are using MVP's desktop, it uses the same software as the inline machine and is great at finding faults, we place down to 16thou pitch and 0402 and if it's set up properly it won't miss a thing, but i agree it's difficult to program. but then you

I had some trials with AOI machines, most I saw Yestech and Saki desktop machines. For the software interface I much prefer Yestech which is very easy to use. But honestly for faults foundings and flexibility Saki is much better, the only thing is th

Hello. I am sourcing machines for an SMT line (for the first time) and would like to understand features of current and earlier model SPI and AOI machines. In the intended application, a high volume of PCAs aren't required to be processed but there
