ABSTRACT
Doing more with less has been the standard operating procedure in manufacturing for the past ten years. Everyone looks for where they can cut corners. Many placement machines have the ability to self-calibrate and then provide their users with capability numbers. In an attempt to save resources manufacturers are using these values in place of true capability studies. That leaves two questions that need to be answered. The first is: How valid are the internally measured numbers? Secondly, if the numbers are not valid, do they still have some value? The simple answer to these questions is they are not valid to predict yield, but they can still have great value to the customer.
