As the second in this two-part
series, The Printed Circuit Design-
er's Guide to... Thermal Manage-
ment with Insulated Metal Sub-
strates, Volume 2, by Didier Mauve
and Robert Art, builds on the mate-
rial presented in the first book by describing
up-to-the-minute products and design tech-
niques for thermal management with IMS.
Starting in the 1950s, the Gerber data format,
complemented with several paper and electronic
files, was used to transfer the physical PCB data
from designers to fabricators and assemblers. RS-
274-D and RS-274X gave us incremental improve-
ments to the Gerber format, but still required
several additional files to transfer all the data. The
274X format is still the most predominant data
transfer package in use today.
One of the biggest
challenges facing
PCB designers is not
understanding the
cost drivers in the
PCB manufacturing process. This article
is the latest in a series that will discuss
these cost drivers (from the PCB manufac-
turer's perspective) and the design deci-
sions that will impact product reliability.
Altium LLC is partnering with the IPC
Education Foundation (IPCEF) and Ardu-
ino to launch the second annual student
electronics design challenge. This com-
petition aims to engage, educate, and
enhance PCB design capabilities while
developing STEM solutions to environ-
mental challenges.
When I-Connect007 asked me to contribute for
this issue on field solvers, I wondered what more
could be added to this extensively discussed
subject, but as a supplier and developer of field
solvers, Polar still gets asked the same questions
both by experienced cus-
tomers who are perhaps
exposed to a new sce-
nario and, as is most wel-
come, by new entrants to
the industry.
Controlling impedance is critical to sig-
nal integrity and board performance in
devices powering everything from high-
speed digital applications to telecom and
RF communication. It is common practice
for designers to include impedance-
related notes with their PCB designs and
rely on the manufacturer to determine
the proper trace parameters.
