Greetings to All
One aspect of this is when to test.  I do understand Werner's desire to have
the raw material tested in some way to determine if it has the needed ppm/C -
but I am still concerned about a multilayer board and the need to test it in
some way to see if it has been cured sufficiently/has appropriate adhesion
enhancement between layers etc to meet the needed ppm/C.

The same questions then become what to test and how to test?

The 6012 group is meeting in Mesa in January and some of the topics are how
and what need adjustments when LF applies.

The other puzzle is when will a fabricator know that the board they make is
to be assembled in a LF process.

Any suggestions or recommendations are welcome
