Hi, I think concept of inspection through AOI is changing. I am struck in confusion.Because some manufacturer say 3D inspection, with 1+4 cameras is ultimate solution. Orbotech also came with 13 cameras at once!Now some say, all these are eyewashing

Manjunath, I prefer orthogonal systems. In my experience they are actually better at detecting coplanarity and HIP defects than multi camera systems. They are obviously limited, in that they can not inspect a component under another component, b

Manjunath The top camera will be used for probably 90-95% of your inspection needs. However, without side cameras that 5-10% of uninspected parts can be a real pain to manually verify. What you need to figure out is what is your product to inspe

Try re-seating the Cognex card and the connectors that plug into it. Make sure the fans on the drawer are clean and functioning. Ive seen bad camera cables cause this as well.

Thanks for the reply Stephen. The time factor sounds logical for moisture invasion during cleaning, probably why there's no articles showing concern about the process. I did try experimenting with some samples and believe it or not could not dupli

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

I can't seem to locate any information/concerns about moisture entrapment in IC packages on the promary side in a double sided SMT assembly using water soluable solder paste when soldering the second side. A typical process would assemble/reflow/cle

Thank you for the detailed input. That gave me material to think on.

Hello, I am planning to use a water wash flux. As this is new to me, would you guys share what should I be aware of? I know cleaning PCBs itself presents issues. If you can share your experience so I can prepare better, it would be great.

The easiest way to prove out the absorbtion theory is to weigh the parts before wash, after wash, and after baking. You probably want to do this with the bare parts in isolation as the fab will pick up considerable moisture. Differences in weight s
