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,
