Hi everyone! I have a question to you about the minimum numbers of prepregs between two conductive layers. In our standards it is specified a minimum of two prepregs to secure good reliability. However, in order to reduce cost we would like to use only one. What kind of drawbacks can I expect? Is there a minimum prepreg thickness or epoxi content that can be used? Every comment is highly appriciated Thanks in advance, //Markus Markus Gauffin M.Sc.
