The EMPF HelpLine has received a request to locate a source of specialty 
circuit boards.  Ultimate use of the assembly will be as a environmental 
sensor.  The base board material (epoxy glass has been used in the past) is 
"coated" with a contiguous aluminum through whatever process, nominal 
thickness approx. .027" or thicker if possible.  The aluminum is then 
patterned through some subtractive process (chemical or mechanical).  Other 
processes will ultimately be accomplished to the board, but initial need is 
to find someone who can do this part of the process. End item is proprietary 
and patent pending at present and non-disclosure documents will be required.
