Nano Dimension Offers Update
on Dragonfly 3D Printer a Year
After Launch
E
The Nano Dimension Dragonfly 3D printer ar-
rived in much fanfare a little over a year ago.
Customers around the world are using them to
print antennas, sensors, and PCBs. At Altium-
Live in Munich, I asked Product Manager Rob-
ert Even to discuss what they've learned in the
year since the Dragonfly debuted, and some
potential uses for 3D printing technology.

Lightning Speed Laminates:
Higher Frequencies Pave Way for
Flexible Circuit Materials
E
The smaller wavelengths of
mmWave frequencies tend
to highlight circuit materi-
al anomalies at those higher
frequencies—anomalies
that
can also influence the radio
frequency (RF) performance
of the circuit. Such material anomalies include
variations in dielectric thickness, dielectric
constant (Dk), copper conductor width and
spacing.

Beyond Design:
The Proximity Effect
E
Skin effect and the proximity effect are man-
ifestations of the same principle—magnetic
lines of flux cannot penetrate a good conduc-
tor. The difference between them is that skin
effect is a reaction to the magnetic fields gen-
erated by current flowing within a conductor.
