Hi Blair, IPC LF Listservers,
Let me take a stab at your note, and hopefully others might add.
<Avnet will supply the materials content in ppm for each of the RoHS
substances, along with other component data such as weight. >
<I'm wondering if I really need this information.>
Yes, You will need this information someplace in your files.
<The directive covers "homogenous materials" as needing to be compliant and
the accepted interpretation is that everything down to the plating on the
leads of a resistor must be compliant. I don't see where the breakdown in
ppm per part and weight are important. If I was taking the approach that my
product weighed 25kg, I could have 25g of lead and be at the 100 ppm level,
however, with the homogenous materials approach this doesn't matter. >
The last I knew "homogenous" (which I can't stand as a technical term) is
almost, or maybe is, in one of the follow on directive EU documents. So yes
you should be concerned. By the Way, if you find the exact release date in
the OJ (Official Journal) please let me or us know.
<So what I am looking for is a statement from the supplier or manufacturer
that the part is RoHS compliant in itself. If all of the parts I use are
compliant, and my processes are compliant, then the assembly is compliant
by default. >
Well Yes, yet if you are a prime "brand name" or other manufacturer or
supplier into the EU you have to, or should I say should, get down to the
detail level of ppm. (More yet that is the short of it)
<Do I need the materials content data for anything? I have heard that some
customers are asking for this, as opposed to simply asking for a statement
of compliance. >
Yes, If asked by an appropriate EU group, etc, you should be able to
present your compliance in detail terms.
Yours in Engineering, Dave
