There is a move under way to consider flip chip for exemption status - I am
not sure how far it got, at the present time the flip chip termination will
be counted as a percentage of the component total content, the fact that it
is sealed in will not exempt it.

On your second point, I doubt it, you could ask the question the other way
around "are ram enhanced battreries non-exempt??". Maybe someone on the list
could answer this second point.......hmmmmmmmmmm if the battery were a 1501
volt device .........then IT WOULD BE EXEMPT...well it is Friday - at least
in California.........8-)

Hi all

I was wondering is any other of the listservers had any views on the
following questions:

   Does lead free apply to types of devices if they are sealed.  This would
   be for example devices that have flip-chips with high-lead bumped solder
   constructed inside a self-contained package assembly.

   As batteries are exempt, does that mean battery backed RAM devices are
   exempt?

regards
Paul
