Hi Harris,

I believe what the customer is asking for is not just gooder material
but
the bestest you can get ;-)

Subject: [TN] What does HIGH GRADE FR-4 mean?

Hi All,

Can anyone define High Grade FR-4? 

I think it's a vague requirement that I see on customer drawing. Is this
something that should be obsolete now because today customer should
really provide the properties of the laminate that they want to use...
eg Tg, Td, Dk.

Can anyone shed some light?

Thanks,
Harris
