Hi, is anyone up to date with the lead free status exemptions list?
ISTR that it changed not to long ago and that not too many are now exempt from being lead free.

For instance, does selling a bare PCB fall within the requirement?
 


Cheers but I'm not sure the 2011 i the latest release - ISTR that there were changes within the past 12-24 months ish.
Some exemptions removed etc.
 

Selling a bare board is no problem if you use a compliant surface finish...
 

That's the point Marc, does a bare board need to be lead free and if so where does it say so?
 

As previously stated, I don't see a point why PCBs with leaded HAL finish couldn't be made for the industries that demand it.

On the other hand, I expect that lead-free HAL finished PCBs can be processed with leaded solder paste as well as lead-free components (with the exception of BGA packages) can. At least it works well for my prototype boards.
 

I often do designs that are going to be soldered with a lead based solder, always use the ENIG finish, HASL is no good for SMD components, the meniscus is the problem.
ENIG covers all eventualities. PBfree of leaded, good shelf life, flat surface finish, proper control of solder volume, no problems and everybody happy:-D
