Thanks Peter,
Wish you could have been there for the last revision. There was a concerted
effort to block inclusion of BGA criteria in the last release. Hopefully we
can do better this time around. Any pictures you can spare would be
appreciated. We have added a new XRay capability and should be able to
support that development also.
What about Flip Chip content from the assembly acceptability viewpoint?
Also with the advent of newer technology applications, wire bond criteria?

Mel,
I whole-heartedly second your desire to see more SMT applications detailed
in the spec, especially BGA mounting and inspection (with X-ray pictures
and how to interpret them).

Amendment 1 to 610C identifies 2.5mm as the correct value. The amendment
was released a couple of months ago and is available on the IPC web site.
By the way, work is in progress toward Revision D to this document. We
have
accumulated a number of comments and would appreciate any additional
information that you would like to see in the new 610. We certainly could
use some additional information on the newer technology applications.
The next technical meeting will be at APEX on 19 Jan.

Hi ALl,
Why are there 2 references to lead length/protrusion in IPC-A-610C. In
'Component Installation Location/Orientation' - point 5.2.7.1 table 5.2
lead
protrusion for class 2 is 2.5mm but in 'Soldering' point 6.2 table 6.1 lead
protrusion for class 2 is 2.3mm. Which one do we use?
