Inge,

When we initially instituted RoHS Compliance we did a full analysis for each and every part / assy we use.  This included complete disassembly and analysis of each and every piece part.  We have 17 file cabinets full of reports and samples where possible.  We also boxed samples and placed them in an unused area of the building.  We developed a maintenance program including critical parts list of parts that needed to be monitored over the course of 12 months, or 5 lots of parts to ensure RoHS Compliance for those parts that failed RoHS Compliance Verification.  It is a daunting task to say the least, and one I have had to do at two different facilities.  Time frame 2 - 3 years.

Exactly what I wanted to debate, but the discussions use (too often) to go 
meandering.
Again, you wobbling netters, has anyone of you been forced to do the 
all-values-analysis and report all individual tests?
At the moment, we must perform hundreds of analysis before the year shift, 
not to mention what becomes a nightmare after Xmas.
If this goes on, we have to build a new house, because the test reports and 
samples must be stored for at least 10 years. The last years, the tendency 
was to omit all incoming inspections in order to save money. Simple minded 
persons thought that you could supersede these tests by creating kilograms 
of requirement specs. Now some risk to be sliding against the other ditch of 
technical perversation.
Indeed, the way to heaven is narrow...

I'm sorry, but wasn't the original question regarding requirements like
testing every value in a series for a material content breakdown?
I am not talking screening every order, where you may catch bad batches
that don't meet the spec stated, but rather, reporting what the actual
expected material content is for a part series like an 0603 5% thick
film resistor.
Would a 51 ohm resistor really have any different measurable material
content from a 75 ohm, or a 1K ohm, for that matter, if all of them were
from the exact same manufacturer, and same resistor series datasheet?
There are thousands of values.  How can we really expect the resistor
company to provide individual breakdowns/test results for each of 1000's
of values of a part they are selling for .01 cent each?

Oh, yes. Absolutely a requirement. We do this on every LOT of
components. You need to do this to ensure there are no Sn99 or
gold-finished parts that would require tinning in order to prevent tin
whisker issues in high rel applications, especially for space and
aviation. The finish described on the component print is not the actual
finish on about 5-8% of all components received, even when there are
stringent clauses in the purchase order. It is too bad that the
component industry is so far out of control. We also get class 5a MSDs
that are not labeled as such, etc. We run that XRF at least 8 hours per
day. For those parts we know we cannot get in the desired finish, we use
a robotic tinning cell made for us by V-Tek. This is truly an amazing
machine, extremely versatile. We can tin right up to the component body
without hurting the components, because the immersion point, immersion
speed, and immersion dwell can be very precisely programmed such that we
get 100% tin/lead coating over the entire termination, not just the part
to be soldered.

Hi all,
have not had time to take part of the discussions for a while. Am
consulting at another company. They needed help with doing analysis of
components.
Boeing is incorporated. I got a list of forbidden materials from them.
Not many can cope with Boeing's requirements. Only a few in whole
Europe! Now, I've a question. Has anyone of you been involved in such
tough demands, namely this one...not only they call for checking the
finish of every component type, but all values (!!) within each
component family. That means, that one sample from EVERY resistor value
must be analyzed and reported to Boeing.  An incredible job list.  Does
this make sense?
