DFM 101: PCB Materials E
One of the biggest challenges
facing PCB designers is under-
standing the cost drivers in
the PCB manufacturing pro-
cess. is article is the first in
a series that will discuss these
cost drivers (from the PCB manufacturer's
perspective) and the design decisions that will
impact product reliability.

All Systems Go! EM Analysis for
Today's System-Level Designs
E
ere are two main reasons to
do EM analysis: to see if the
signals in the design will meet
your performance specifica-
tions, and to see whether the
design has unintended EM
interactions in the circuit or system. Since
domain-level requirements vary, not all EM
solvers are the same.

Connect the Dots: A Closer Look
at Surface Finish
E
e final surface finish of a
PCB is an important consid-
eration. is coating between
your components and the bare
board is applied to ensure sol-
derability and protect any
exposed copper circuitry. Selecting the right
type of surface finish can be daunting, and for
good reasons.

Standard of Excellence:
Dare to Share
E
We oen talk about the value of working closely
with your vendors to the point of making them
partners. is strategy makes sense. e closer
you are to your vendors, the more you help
them, the better vendors they will be, and most
importantly the better partners they will be.
Now let's take that idea to the next level, all the
way to the point of a true partnership.
