We are a small PCB shop producing multilayer boards.  Does anyone know
any advantages or
disadvantages in using double treated copper as opposed to standard "slick"
copper for inner layers.
We are concerned about boards delaminating after some time in the field.
Currently we use standard
FR4 with a slick finish and do not have any known problems with
delamination, but are not 100% sure
about the product over time.  Thanks in advance for any input.
