Omron AOI | 20 August, 2010

I just found out that we have an older Omron VT-WIN that we are not using. I do not know anything about the machine, but I am curious if it is worth trying to bring onto the production floor and use it for inspection. Can anyone tell me anything about the machine and it capabilities.

Hi, I work with Omron AOI for almost 5 years. Sorry for the late reply, but I visit this site very seldom Basically Omron are considered as the best in solder joint inspection because it used patented 3 colour highlight principle and in 99% the missing meniscus is identified and detected. VT-WIN2 has another advantage - you can choose 3 main pixel size resolutions for inspection out from a group of sizes starting from 10um up to 50um. You can inspect small components 0201 or 0402 with 10um, and bid FETs and connectors with 50um, optimizing the inspection time. Everything is in millions of colours, which is good and not very good sometimes. The week side is lifted leads inspection (has no laser scan and identification like some other AOI machines), polarity is subject to continuous update due to the different marking (colour) by the manufacturer. If you need more detailed info send me an e-mail to I'd like to help you as much as I can:-))

Hello, tell me please, what type of file do you need to make a program for Omron AOI, only centroid data?

Hi, you can generate your prgm without any gerber date, you should save an image and after that just paste your components, you can also use Multiform software to convert CAD data into Omron data file, which can be used to generate the final prgm. But it is very sensitive to formatting, etc. If the module (pcb) is not very complicated I can advise you to use the first one!

We don't have yet the Omron Aoi, but will come soon. So please tell me, what will be the most challenging thing with Omorn AOI.And how will be the best way to make the library, after part number or after shape ? Thanks You.

Hi, I don't know if you have any AOI experience, so it is difficult to answer to your first question. Omron AOI software has a library, which is based on Jedec, so you can use just 10-15 different general models and will create hundreds of library components with specific characteristics. My advice is to be patient and to wait until somebody from Omron comes and gives you some training. Just speaking general words while you have no the faintest idea how the machine looks and operates is not practical.

As with most Aois centroid data is very time saving when your pcb has 20 or more components. This of course can be variable with the quality of the data and your ability to modify it to suit your needs.

Omron systems can scan your pcb and merge the centroid data. At the same time the software makes adjustment to the landing areas (pad dimensions).

I have been involved with Aois for many years and was underway for one of the leading manufactures in Europe doing application support. From what I have recently seen Omron should have the simplest and fastest program generation times of any of the current systems on the market.

Namaste, Kevin Tough

From what I have seen of the Omron software your most interesting challenge and prerequisite for a clean and complete inspection is a full understanding of the color triangle and it's settings. I know you can find almost the same interface/GUI in the open source software GIMP. To find this you may have to right-click on one of the tabs in the color chooser.

If you are starting to build a library there are several things to consider. One of the most important points is to take some time to think about what best fits your company's strategy/planning. If such does not exist then it should and you can start it. The Ipc and their naming standards are playing a larger and larger role in the industry in the last few years. Search for "Ipc Land Patterns" or "Ipc naming convention" on the Web and you should get some ideas. I personally use a mix of the Ipc names with the geometric information I can measure from components quickly with a caliper. If your name includes the necessary information you can tell if the pattern has been changed from it's original form. This can become a great advantage dependent on how many persons are working with the library and their knowledge/interest level.
