RoHS interpretation

Seems that an IC could be "banned" if the leadframe *plating* (their
"material") has more than 0.1% of lead even tho the over-all percentage
of lead for the IC might be 0.01%.
Is this a correct interpretation?

However, the plating could be pure lead and the IC would "pass"
because that could be considered a high melting point solder even tho
the over-all percentage of lead for the IC might be (say) 1%.
Is this a correct interpretation?

And..what solder is "high melting point" solder?
Where is the "boundary"?

I think you are right IMO. Unfortunately. I tested one of our IC's and it
had 0.3% Pb referred to total metal. This was with a 10 micron plating of
60/40 though. It stinks, doesn't it? Must be the rancid smell of
beaurocrats. Maybe US regulators are more practical and take some care
about manufacturers? Not all electronics of high value is designed to last
a few months before obsolesence.

Stupid as it may seem, the answer is yes.

Not sure if you'd have to apply for an exemprion in that case.
And..what solder is "high melting point" solder?

I think it's mentioned somewhere on the EU site.
Where is the "boundary"?

Somewhere in la-la land.

Be advised that on IC leadframes, some companies used to tin them
with Sn85Pb15 and now the RoHS replacement is 100 percent (!!!) tin plating.
Nevermind that original alloy could be interpreted as being a high MP
solder and therefore *not* covered...now everyone will be facing
!failures! of their electronic widgets in the field, due to very nice
shorts, thank you!

I'd say make your own interpretation and ship it in these cases. After all,
WHO is going to test it?

Some bureaucrat that wants to make a name for himself and become
governor or such.
Nasty BS has happened due to such power-hungry idiots.
