Hi All!

I am new to the list trying to learn about different PC board
substrates. I think CEM-1 may be what I want but am trying to
confirm. I've scoured the net today, as well as searched this list's
archives, but haven't seen exactly what I am trying to find out ...my
apologies if I've missed it somewhere.

I have some PC board stock (purchased in 2002) that measures .056 in
thickness and is single-sided board. It is an off-white/light tan
color on the unclad side and appears whitish on the cut sides. Under
magnification the cut edges appear to be almost an open cell type resin
(possibly a paper/resin combo?). It's definitely not a stranded fiber
as is some other stock that I have. Anyone have any ideas on what this
substrate is?

I want to get some more of this, or similar board, and am planning to
cut it into very small sizes. It looks like .062 single sided board
would work for me and be relatively easy to cut. I plan to cut using
either my small hobby table saw with suitable blade or possibly my band
saw with metal cutting blade.

Easy (relatively) cutting is my main objectives, other structural and
electrical properties are not critical for my needs. Any help in
determining the best material for my needs is appreciated.

Thanks,
John Fell
