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 Arlon,
and 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. |
