Hi Jeff,
is it possible to buy the proceedings, we use XILINX 560 (superBGA) and are
a little nervous about the soldering process, anything useful is of
interest.
Regards
Ingemar Hernefjord
Ericsson Microwave Systems
PS. Cameron, are you also interested in BGA's? Who at your lab is king of
soldering? We plan to visit you one day. Did you visit the Boston Chapter?
/Ingemar

Subject: [TN] Meeting, Boston (MA/USA) IPC/DC Sept 19 6pm
,
DFMs and DFAs for PCB's with BGA's
The Greater Boston Chapter of the IPC Designer's Council will
hold its next meeting on Tuesday, September 19th at the Best
Western TLC Hotel in Waltham at 6pm.
Topic and Speaker:
Dave Hoover, Field Applications Engineer for McCurdy Circuits,
will present on designing boards to accommodate BGA packages.
As BGAs have become the package of choice, pin counts are now
routinely reaching 500 pins and many devices exist at 1k pins
or beyond. Pitch between solder balls is rapidly falling, as
1mm becomes commonplace and .8, .65, even .5 or smaller can be
found. These densities place new demands on the underlying
board technology, and care must be taken to assure production
needs can be met. Guidelines suited for production in typical
fabrication environments will be presented, as well as a look
at assembly, rework, and materials needs.
Agenda:
Please note there is a $15 meeting fee for members, $20 for
non-members. Pizza/soft drinks will be served.
6:00 Arrivals and Pizza
6:45 Chapter Business
7:00 Dave Hoover, McCurdy Ckts, DFM/DFA for PCBs w/BGAs
Location/Directions:
The Best Western TLC Hotel in Waltham is located at exit 27A
off route 95/128, proceed east on Totten Pond Rd and the hotel
is on the left.
RSVP's requested:
Please RSVP by sending an email to [log in to unmask] with
the subject "RSVP IPC/DC" by Friday midday, Sept. 15th. Please
treat this as a commitment to attend.
President's Note:
At last we're able to begin this years meeting season. Amid
the activity of PCD-East, IPCWorks, and SMTA International I
hope you will find the time to join us as we try to establish
a nearly monthly meeting through to next spring. Perhaps our
series will provide some exposure to anyone not able to give
the several days or a week's time block to one of these major
events.
As the new season gets started I will hope we can attract more
help to the Steering Committee, as there are many services and
aspects of the group we would like to move forward if we can
find the help. Steering meetings are held at 6pm, 2nd Tuesday
of each month at Victoria Station restaurant in Burlington, on
the Middlesex Turnpike across from the Burlington Mall.
Mission:
Design is not called "do" for a reason. Done properly, the
design process is a creative problem solving discipline. To
address the packaging needs of electronics for today and to-
morrow, the physical designer needs an avenue to get exposed
and familiar with many different techniques and technologies.
The Greater Boston Chapter of the IPC Designer's Council is
committed to presenting stake holders from every aspect of the
packaging realm. Our hope is to help you gain insight and un-
derstanding of the many possibilities in solving core problems.
Your attendance, help and participation are most welcome.
Thanks in advance, and best regards!
