To what extent has the PCB industry changed to single ply for pre-preg as
opposed to core which has been available in single ply for a long time. What
are the fears about single ply pre-preg? Are 2 plies really better than 1 thick
one?
What are the attitudes towards so called "green laminate"? Is it simply a case
of eliminating bromine, is it vital to meet UL V- 0 if the alternative could
have such an impact on the environment?
These questions were prompted by a major user of PCBs in Europe.
