We usually receive them in batches of a few hundred, and occasionally from catalog vendors like Mouser. Inspection has been inconclusive. They don't have to be bent much to cause a problem. I'm wondering if it's just the nature of the beast.

We have a board with an LQFP-176 with 0.5mm pitch. We regularly have to rework these due to unsoldered pins, which is due to pins that are slightly bent upward. We believe that we are receiving them this way, but it may also be due to handling on o

Some causes of skewing. If you have exhausted all mechanical problems for that head. Pickup data from tray is incorrect. If you aren't picking up in the exact centre it is possible that the component is being skewed after vision adjustment i.e. cent

That's a great point about air consumption, don't reduce the 1/2 inch air line requirement, meet the CFM air requirement and of course dry shop air. Check the Auto oiler for the CTA is running correctly, 5W 30 NON Detergent oil only. Attached is a pi

Thanks for adding that, Daniel! It always helps the rest of us when the solution to a problem is published. Plus, my brain won't rest until I know.

Watch the air pressure gauge and make sure you have a good steady air pressure. I don't know about the Rad 5 but the Rad 3 was sensitive to fluctuations in air pressure. By any chance do you have a VCD running nearby when you are having the problems?

I forget which type of CTA that machine has so I probably won't be much help. It's been ages since I worked on them but it doesn't look like you'll find many people that have. That said, usually if you get things aligned properly and it still bends
