What does "green" mean?  The color of the laminate (or the soldermask)?
Halogen-free?  Compatible with Pb-free assembly?  If the latter, what is the
Pb-free alternative being used?

What material you get will depend on how you (or I suppose more
appropriately, the board fabrication house) answered these questions.

Hello Designer Council members

At the company I am working for is calling out matterial .062 thick FR4
green
copperclad laminate for their bare board.

My question for the form:

When this design was done in the Northeast by the electrical engineer and
outsourced to a board assembly house as a turnkey component.  What type of
quality problems can I expect to deal with durning final assembly and final
test?  What long term (customer returns) problems may result from this?  Do
the
board fabracation houses on the east coast march to a different drummer than
the rest of the country?  The electrical engineer does not want to change
the
drawing to specify what laminate matterial he truly intends to use.  The
last
company I worked for also had this same type of problem.  The electrical
engineer designs/releases and I have to fix his mistakes.
