Polar Instruments Announces Additive
Transmission Line Support for Si9000e
In addition to modeling loss and impedance, the Si9000e is
capable of taking account of
surface roughness effects and
offers several industry-standard
methods for estimating the effects
of surface profiles. Other useful
features include a traffic signal
warning for vias that require stub
reduction by backdrilling, and the
ability to estimate crosstalk.
How Good Design
Enables Sustainable
PCBs
Sustainability has become a key
focus for PCB companies seeking
to reduce waste, conserve energy,
and optimize resources. While
many discussions on sustainability
center around materials or energy-
efficient processes, PCB design
is an often overlooked factor that
lies at the heart of manufacturing.
The Art and Science of PCB Floor
Planning: A Comprehensive Guide
One of the
foundational stages
of PCB design is
floor planning,
a phase where
the placement of
components and
the flow of signals
are meticulously
mapped out. A good floor plan ensures that the PCB performs
well, is easy to manufacture, and meets all mechanical and
electrical requirements.

Floor Planning
Without a Floor
By a show of hands, how
many PCB designers have
been asked to start a layout
without a board outline, keep-out zones, or even height constraints?
How many have had to work within a specific enclosure before the
schematic was finalized? If this sounds familiar, you're not alone.
Elementary Mr.
Watson: Routing
Hunger Games—May
the Traces Be Ever
in Your Favor
I'd like to share a harsh truth, and I
say this as a friend: PCB designers
are often their own worst enemy.
It's rarely the complexity of the
circuit, the last-minute changes
from mechanical, the limited
enclosure space, or the ever-
expanding list of design rules that
send projects to the dust heap
of failed boards. More often, it's
our own decisions.
