Rob,
 
I have a backlighting ratings procedure on Adobe Acrobat format if you want it.  I think this is what you are looking for.  Most of the facilities I service use this method for their backlight evaluation.

Hi Technetter's;

Does anyone have any info (website, standard, company, etc) regarding backlight testing, evaluation and rating of electroless copper processed holes?

Thanks in advance. ---------------------------------------------------
