Matthias, what a great offer to share the additional procedures with industry!
Members helping members is what makes any professional association good.

Content is the only important issue, we'll format for commonality.  The folks who
have IPC-7711 "Rework of Electronic Assemblies" (remove/replace components) and
IPC-7721 Repair and Modification of Printed Boards and Electronic Assemblies"
(board/conductor/pad/PTH repair and mod) are already aware that they receive two
years of updates (subscription service) as part of their purchase price. These
documents were published in three-ring binders to permit adding new procedures and so
that companies can insert their unique requirements. Look to http://www.ipc.org and
click on the IPC Bookstore link for more info.

The leaders of the developing task groups are always looking for suggested additions
to both manuals. Another topic being considered is procedures to reball BGAs.  ANYONE
with other ideas and procedures to share is invited to do so.

Please contact me off-net [log in to unmask] or 847.509.9700x393 and we'll discuss
further.  Jack

Hello TechNetters,

in IPC-7711 (Rework of Electronic Assemblies) are no procedures for
modifications like insertion of additional components which have no
corresponding lands in the layout. I think this happens very often
during the prototyping phase or the very first production runs. I
know some companies which have procedures (how to fix these parts,
where to place/not to place them, stacked mounting of chip Rs and
Cs and so on). Is it planned to publish with the next updates such
procedures? Perhaps I could get the permission from at least one of
my customers to send his procedures to someone at IPC, however, it is
absolutely not in the IPC-7711 style. But maybe it has some good
ideas.

Regards
Matthias Mansfeld
