Hello fellow experts! Does anyone have a SPI machine that can calculate Cpk for the solder paste height across the PCB or for selected locations? Any feedback will be appreciated.

5 ppm from cylinders, thank you for taking the time to respond. Originally I ran no spec nitrogen, and got good results, when I started having issues I changed to 4.8 spec

I had also increased my flux to see if that helped, it did not. 2mm lead length, 5.08 spacing Thank you

How thick is this pallet? 6mm, 8mm, 10mm? I would look at: Make sure you're pot height is correct (lead clearance). If you are burrying the pallet in the fountain, your going to "push" a large volume away. The solder "push" should not plow over t
