We have a question (actually several) from an IPC member in Germany.  If 
you can help please send your replies to me or to TechNet.  Thank you.

"It is a known fact that our customers are asking for much higher 
densities and they are using their 'safety belt' by specifying '100% 
electrically tested.'  And with this the whole problem starts.

-What is 100% tested?
One way to understand this specification is:  100% of all boards have 
undergone a test.  But the better way would be 100% of all test-points 
have been tested and it was found that there are no opens or shorts 
between these measurement points.

-What does the industry need?
The PCB manufacturers would need a so-called net-list that gives the 
location of all end-points which have a significance.  I do know that 
there is test equipment that is checking carefully all those terminal 
points but usually they are too slow for mass production (and crunching 
out several thousand square meter of PCBs every day need fast electrical 
testers...)

The usual way of trying to find a 'golden board' becomes less and less 
practical.  It is the customer that has to provide such data.  And here 
my question starts:

	-Are you aware of available softwarre for such net-lists?
	-Is there a working group on this particular subject?
	-How do customers of your industry react to this problem?  (In 
	Germany many of the larger companies are will aware of the problem but 
	they prefer not to 'see' it...)

There is a small company in Germany that claims being able to offer a 
software package at about $23,000 for the first and about $6,900 for each 
subsequent programme (apparently each format has to have a separate 
program at each CAD site, so that it is a customer problem rather than a 
PCB manufacturer problem).  Have you heard of similar activities anywhere 
else in USA or Europe?"
