Design Criteria for Flexible Circuits
The Greater Boston Chapter of the IPC Designer's Council will
hold its next meeting on Monday, Nov 20th at 6pm in the
conference room at iRobot in Burlington MA.
Brad Saunders, of Cosmotronic, will present the current out-
look for flex and rigid flex design practices and standards.
He will cover single, double and multilayer flex and rigid
flex configurations in low to high volume. Implications on
single ended and differential impedance will be discussed.
Cost drivers and complexities will be analyzed, particularly
book binder, bend radius, and squeeze-out along with micro
vias and other current techniques. Upcoming specification
updates will also be discussed.
Mr Saunders is in Technical Sales for Cosmotronc/Winonics,
a rigid and rigid/flex quick turn commercial and military
PWB supplier with over 35 years in the business. He has
held numerous industry positions at vendor, OEM and Prime
Contractor organizations and is a noted resource in the
region.
Agenda:
6:00 pm, Arrivals/Pizza, mtg fee $5/Member, $10/Non-member
6:45 Jeff Seeger - Chapter Update
7:00 Brad Saunders, Flex Design Criteria
Location:
iRobot, 63 South Ave, Burlington MA. Directly across from
the Burlington Mall just off of Middlesex Turnpike; South
Ave has Long's Jeweler's on the corner and Tower Records
is visible just down the hill. As you proceed up South Ave
iRobot's front door is at the first left.
RSVP's needed:
Please RSVP to either Jeff Seeger [log in to unmask]
or Janice Lund [log in to unmask] by Monday noon, 20-Nov.
We need this to plan the food order.
President's Note:
I'm pleased to announce the beginning of our season, and
a new meeting venue. It's difficult to obtain the free
sites that allow minimal meeting fees, many thanks to
Janice and iRobot for what I hope to be a great location.
We're looking to announce a schedule of topics to include
Regulatory Compliance, Signal and Power Integrity, the
new IPC-7851 footprint standard, and of course everyone's
favorite, RoHS and WEEE. Please send your topic needs
and/or candidate speakers to [log in to unmask]
we would appreciate your feedback.
The Flex and Rigid-Flex categories continue to be growth
oriented markets and have remained a robust on-shore pre-
sence. Usually a curiosity, sometimes a necessity, this
style of printed board has many uses but comes at a price
of complexity and perspective. Join us to learn how and
where to deploy this technology to its best use, and how
to get it right the first time.
Mission:
The physical design of circuit boards is only getting more
complex. Only the physical designer can hope to sort out
the myriad interests that add up to a printed circuit board.
This presents an opportunity to avoid competing with off-
shore labor rates doing routine place and route. Add value!
The Greater Boston Chapter of the IPC Designer's Council
is trying to bring the stake holders from every discipline,
to show you their problems and solutions so you can add to
your arsenal of knowledge.
Your help and participation would be most appreciated, how
about getting involved!
Thanks and regards,
Jeff Seeger, CTO, Applied CAD Knowledge Inc.
President, Greater Boston Chapter, IPC Designer's Council
