The job file format is currently a preliminary.
It can be modified (I already asked for modifications and clarification).
Could you give a link to a manufactured that explains applications (and show a few boards) where
different substrates are used.
Karel Tavernier (Ucamco) and me know some constrains about RF, but we are not RF specialists.
