Today I learned a tremendous amount by reading several parts of books and papers. I am starting to realize Printed Circuit Boards are the focus of my group (so I now know what PCB stands for). I read a few chapters from a booklet titled Printed Circuit Board Basics just to get an idea of the type of products my group produces. It was valuable, but not as valuable as the time Chuck Bassett spent with me showing me some of the terminology and what is actually was on a circuit board.
I reread Chapter 14 out of my AP Stat book to get me a better idea of Multivariate Regression, which is what I think will be the process I will be shooting for to complete my first product. But that is only a guess at this point.
I ran regression calculations on a large number of variable versus the two different measures of time used in manufacturing (Cycle Time and Touch Time). I found the process they have been using does not correlate as well as some other possibilities. My job tomorrow and the next day is to come up with a way to better predict these two measures of time given the values of certain variables.
I met with Michael Molacek to get an idea of what he wants from this product. He says I have free reign, just try to come up with a better prediction tool. That is my goal. My biggest problem is the data is partial or sporadic. My thoughts are to remove the partial data and use only the data which is complete to make my predictions. I keep you posted.
