Oh... and as a note of caution...
I was disappointed when I first bought my specs from the IPC because I
bought the CD versions... They are protected CD's that don't allow you to
print out the document... I found this useless...
I turned my copies back in and exchanged them for the Printed versions
because of this annoying feature.
You may want to carefully consider if the CD's are valuable to you... they
charge more for them too, which didn't make any sense to me either...
I am very happy with the paper versions... although I would have wished that
the CD versions were printable. Then I would not have had an issue with
them.

Hi Bryan,
The Designer's Council negotiated some discounts on certain specs deemed
important to designers... With your membership you can get a 50% off
discount on these specs. Plus your $50.00 coupon you get when you renew your
membership is valid for use to get more off on the specs you purchase.
Here's a link to the discount page... you will want to check it out.

Maybe some of the other designers can tell you what specs they use on a
regular basis... I use the IPC-2221,IPC-2222,IPC-D-325, IPC-2615, IPC-6012,
J-STD-001, IPC-SM-782, IPC-D-316, IPC-4101, IPC/JPCA-2315, IPC-2223.
The IPC-SM-782 is old... there is a new spec out for land patterns but I
have not purchased it yet. It's IPC-7351 ... I plan to get it sometime this
year.

Subject: [DC] IPC Design Specifications
Hello!
I recently joined the Designer's Council, and I wanted to get some input
from those of you out there that have been working with IPC specifications.
I have been designing boards with through-hole, SMT and mixed technologies
for some time, but have never had the IPC specs for designing them. In an
effort to "get with the program", I wanted to purchase the specs that would
be most beneficial. Can anyone tell me what specifications best cover the
design of T/H and SMT technology boards?
I also am working on some designs where AC power is present on the boards,
and I am concerned about trace separation for a given voltage. I know that
there are specifications out there that address this, but I am not sure if
they are UL or IPC based. Can anyone point me in the direction of these
specs?
Thanks in advance for your help!
