For upside down and rotated parts try using the index mark (F6) in the package database for that component, at least then the machine should look for a unique feature on the bottom and if it cannot find it the part will be rejected. For the index ma

I am interested in learning if there are any standards regarding markings (text) that appear on components. In order to properly supply an OCR/V to my company's customers I need to find more information regarding component markings to develop a sati

I don't know about a poster, but we just print the Data Sheet for parts with questionable polarity markings. Just remember, that not all SMT LEDs are marked by Cathode. We have ONE LED that we use that the manufacturer puts a dot on the anode side.

With AOI it really depends on what you are testing. Not only what criteria, but what different types of components. We run a high volume low mix application for automotive checking for presense, positional accuracy, and all solder joints. We curre

I am looking for a poster (or anything) that shows Polarity Markings for different SMT Components. I would like something for SMT Operators and SMT Setup to be able to look at when training or when they are questioning the polarity of a part. If anyb

We are just looking for something to get trainees familiar with the different polarity marking so they know what to look for.

That is the rub here, isn�t it? For those posting, it�s easier [but much slower] to start a new thread than to search the archives. [And posters could view their issue so unique and novel that it could never have been discussed several years earlie

Hi, After you got datasheets of component shapes (only new one) and enter it to SMT machine library (including Polarity Mark and Position), you can use our software to simulate and fix all angles. Also, our software has tools to add Polarity informa

You are on the right track Ismir. Essentially however, as the programmer of the machine, I am the one that creates the PCB with the errors to benchmark the settings for the machine. No secret lab though! :-) Easy enough for most any AOI machine to

If it was only 1 or 2 components on a reel that were backwards, I would lean more likely the cause just being the component was wrong direction in Tape from factory. Not much you can do from a Pick & Place perspective, generally.. Most machines use
