Ed in the below text (or here); you should be able to click on :
http://www.nemi.org ;
the web site is fairly comprehensive and self-explanatory .
Otherwise, few of us is trying to get the hold of it .
Keep you posted if possible, or somebody else could

Ch oose Alloy
Hi leadfree forum members
I am a newcomer to this forum and I am just learning what are you talking
about.
I am chief of process engineering in PCB plant.My interest in lead-free
issue is obvious:as PCB manufacturer we have to prepare ourself for a new
era.
I am just wandering: where and how I can find a short describtion of current
situation?
You are mentioning the last report of NEMI.
What it is NEMI?
I guess,that the report you are mentioning is dealing with alloys as
substitution of Pb/Sn.
What is written in?As IPC member,how can I get it?
Regards
Edward
