Phil,
A homogeneous material is either:
a compound
an element or
a mixture that is the same throughout.
Examples of the three are:
Sodium chloride - Table salt (if you exclude the added potassium iodide
:) )
Aluminium
A brick
The REALLY stupid part in all this is the EU saying that the finish on a
leadframe is mechanically separable from the lead itself. As a chemist,
I might be able to do it chemically, but make one awful mess in the
process.
Does that help?

Subject: [LF] definition of Homogeneous
Good Afternoon,
It may have been discussed, but can some one point me at a layman's
definition of homogeneous as it pertains to lead-free. All the
definitions I have seen make my eyes roll into my head and leave me
babbling in the corner. I need to be able to explain this in plain
English to my engineering force.
Thanks in advance,
Phil Nutting
