Other Laminates :-
 
FR2 :-
Is a Phenolic paper re-enforced laminate, it's much cheaper but not as strong or stable. Widely used in cost conscious applications i.e. consumer goods. For the inquisitive the basic resin is made from phenol and formaldehyde.  
 
PTFE :-
Used in high frequency applications. Laminate has a much lower dielectric constant. Two main sources are Arlonand Rogers-Corp click on either name to link onto respective web sites. PTFE is very very expensive laminate.
 
CEM :-
Probably best classed as modern mixed up laminates, as these can be made in a number of different ways. Some have re-enforced outer layers, [which make a first class scoring laminate]  others are made from chopped fibres instead of the layers of solid matting. Normally not translucent like FR4 and can even be coloured.
 
Flexible :-
Lots of variants of this type of laminate, which now even include some semi flex types, a sort of mixture of flexible and rigid material. Our first encounter with this type of laminate was a good number of years ago for a customer who wanted to make flashing dog collars. Not our most favorable type of material to work with, but manufacturing a few circuits with it can easily brighten up our day. Try looking at the  krempel  website for more information.
