Hi all,
Recently I have been asked about "Halogen free Solder Mask".
As I understand, "Halogen Free" restrictions on PCB are expexted to be
employed in summer 2007 ( ? ).
What are the definitions of "Halogen free" ???
I had impression,that definition is based on limit of % wt ( 0.1% ???) of
PCB. If this is true , taking into account amount of Solder mask on PCB and
possible % of halogens in Solder Mask formulations , it seems to me, that
such contributions of Halogens originated in Solder Mask is neglible.
Pls comment.
regards to all
Edward
