David, Since it has been some time since I've posted this, we are few steps ferder with the search to an AOI. I'm already having contact with Duncan from Omron. He gave me almost the same answers to my questions.Accept for the programming time, whi

I recommanded AOI inspection as I am a AOI programmer too. 1.Yes u have to write programm for every PCB design,but u maintain the standard library. 2.If u have standard library and SMT machine CAD file ,then it doesnt take more than 30 mins. 3.No I

Currently I'm working on a study of the quality of our SMD process. For this I am investigating the possibility of adding an of-line AOI There has been previous research done (late 2007), bij the company I work for. Since there could have changed

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

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

You're right! Whether "Pattern matching" or "Pixel recognition", in both cases, it is the operating person who will make an inference from the results obtained. This makes IPC knowledge the key to AOI usage. "Quality" is never introduced into a pro

You could spend 30 mins inspecting a modestly complex board manually using a magnifier/scope and still miss things. Humans get distracted, bored and tired. It is also difficult or impossible to visually inspect some faults like mild tombstones or qu

Dear all, Have anyone deal with X-Out boards? These defects are declared if one cavity or more from multi cavity boards are defective. There have been a request to use these boards in order to reduce the multi cavity board spoilage at supplier. Ho

I worked for a company with a Mirtec. It's a great machine. The sales guy kept going on about needing a golden board. But if you program very carefully and verify each part as you add it to the library, you don't even need a golden board. If you ha

I will review some of the advantages/disadvantages of AOI vs. X-Ray one by one according to the main differences that you may find between them. * AOI uses optics that can "see" only visible elements. X-Ray can "see" hidden elements. There is a ve
