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 Edward Szpruch Eltek Ltd P.O.Box 159 ; 49101 Petah Tikva Israel Tel ++972 3 9395050 , Fax ++972 3 9309581 e-mail [log in to unmask] web site : www.eltekglobal.com
