These two recent postings almost seem to shed a little bit of light to
the end of this long tunnel. I have been watching these postings for 4
months now looking for information more directed to my company's
product. We are a manufacturer of microwave frequency cable assemblies.
The better part of our customer base does not want to hear of a change
in our solder compound, good old Sn63/Pb37. We do however have a client
base in Europe and Asia and must satisfy their market needs. Does anyone
have information more directed to our industry rather PCB manufacturing?

Hi - I hope this helps,
RoHS Compliance: The European Commission will formally adopt the
following waivers (exemptions) some time next month (April):
The New Waivers (Exemptions) will be:
- Lead used in compliance-pin VHDM (very high density medium) connector
systems
- Lead as coating material for thermal conduction module C-ring
- Lead and cadmium in optical and filter glass
- Lead in solders consisting of more than two elements for the
connection between the pins and the package of microprocessors with a
lead content of more than 85% in proportion to tin-lead content -
exemption until 2010
- Lead in high melting temperature solders (I,e, tin-lead solder alloys
containing more than 85% lead) and any lower melting temperature solder
required to be used with a high melting temperature solder to complete a
viable electrical connection
- Lead in solders to complete a viable electrical connection internal to
certain integrated circuit packages (Flip Chips) - exemption until 2010.

Hi Dave!
This is what I found:
The following changes and additions to the list of exemptions
within
the RoHS Annex have been adopted and should enter the official
Journal in February or March.
Paragraph 7 previously read:
"7. Lead in high melting temperature type solders (i.e. tin-lead
solder alloys containing more than 85 % lead),
lead in solders for servers, storage and storage array systems
(exemption granted until 2010),lead in solders for network
infrastructure equipment for switching, signalling, transmission
as
well as network management for telecommunication,lead in
electronic
ceramic parts (e.g. piezoelectronic devices)."
This will be replaced with:
"7. Lead based alloys containing 85% by weight or more lead,lead
in
solders for servers, storage and storage array systems network
infrastructure equipment for switching, signalling, transmission
as
well as network management for telecommunications,lead in
electronic
ceramic parts (e.g. piezoelectronic devices)."
Kind regards,

A IC vendor, when questioned about a particular BGA part we are using
made the following statement:
"This BGA is almost RoHS compliant today. It uses 90/10 Pb/Sn spheres
and bumps which meet RoHS exemption requirements. However, to be fully
RoHS compliant, we must switch from high-Pb to no-Pb capacitor attach.
This <>may happen in ~2006. There are no plans to further modify the
this BGA package."
Question #1 - Is there an exemption to the RoHS rules with reguards to
high temp lead solders?
