Im interested in learning about the wide world of standards as pertains to 
RF materials and substrates.  What are the ISO standards that are pertinent 
to Microwave/RF substrates, PWB, and metalization?  How do these standards 
relate to IPC standards?  ASTM standards?  Who develops these standards?  
When and where do the committees meet?  What about STEP?  Any information 
would be appreciated.  Thanks.
