You should be fine! best practice for a situation like this would be to run a solder sample, either flux it and run through wave, or screen print, don't place parts and run through reflow. look for proper wetting characteristics if you see de-wetting

Hi Steve, My company offers this kind of system in two different versions ; a low-cost semi-automatic configuration using barcode labels and a closed-loop configuration using RFID tags to retrofit existing feeders into smart feeders. Please contac

I am sorry my friend, but I can't recall that specific error number. But it would help if you explain a little bit more about your problem. Remember that an error code Do Not necessary points to a direct root-cause of a problem. First of all we nee

From looking at your images I would say it could be poor solderability on the terminations of the component itself. Can you get your hands on a different date code and try them out?

Our AOI machine can save various views of the same part number since we all know that different manufacturers will mark parts differently, some manufacturers vary their own marks. We get parts from the same manufacturer but different date codes that

The clutches are brand new and oil free. As I stated above we run newer components as a general rule. I see this happening across different date codes, and different manufacturers. I have tried routing the overlay tape like the diagram on the feeder,

Well it looks like you answered you own question. Why would you send the component out for cross section. Why wouldn't you try a different manufacture, assuming you have already used different date codes on this supplier. Is your company contract man
