Dear Sir : How are you. I am a graduate student in the Industrial Engineering department of Oklahoma State University. I am working on my study in developing a cost estimate equation for plain PCB. This equation is base on the physical feature and special requirement of the plain PCB and uses the forward stepwise regression to discover the relationship between all different factors. Within certain restrictions a designer can use this equation to estimate the cost of a PCB design. The reason I write you this letter is that I need a huge data base of PCBs with their specifications to find the equation. I am searching all the PCB manufactures asking their catalogs for my database. So I am wondering would there be any of you willing to help me or send me a copy of your product catalog or any suggestion for my research. Thanks for your very much.
