For component loss that cannot be accounted for by the placement machine's computer I would have the operators collect all loose components from the feeder setup area and in and around the placement machines after each product batch run. This is cert

You're welcome John, it can get confusing but what's important is that machine's exhibit accuracy AND repeatability. Generally, high Cp values represent high repeatability (for instance in darts: hitting a triple 20 over and over means you're very re

Dave, thanks for the info. This sounds like it would verify the presence of an open. We have verified that these balls are open and I am trying to figure out if we are fracturing or not wetting. causing these opens. I would use the die method on ne
