try contacting CSI. They really don't have a web site but they have an e-mail address. We have information on manufacturing from them. You can contact them and maybe have them fax it out to you. If not I can fax you what I have. Their e-mail is..... sales@circuitservice.com... I hope this helps. Good Luck...
