If electricity were a group of college
students, then power electronics and the
PCB designers who dive into it would
insist on driving the car on every road trip
because they know the car inside and
out—they're the students with jumper
cables in the trunk, a tire pressure gauge
in the glove box, and snacks stashed
under the seat.
The evolution of modern processors, marked by faster
edge transitions, reduced output impedance, and
increasingly complex bus architectures, has signifi-
cantly augmented the demands on PCB infrastruc-
ture. These challenges are compounded by AI-driven
graphics processing units (GPUs), which require excep-
tionally high-power delivery at ultra-low operating
voltages, placing greater stress on power integrity and
layout design..
There's a debilitating loyalty lingering
in the design community: Designers
are still specifying copper using
ounces per square foot (oz/ft²), a unit
of mass per area, not thickness. That
may be fine for ordering roofing mate-
rial, but it introduces real problems
when trying to define or verify the
finished copper thickness of a circuit
board.
Host Nolan Johnson sits down with resident expert
John Johnson, Director of Quality and Advanced
Technology at American Standard Circuits, to discuss
how material selection influences the Ultra HDI (UHDI)
manufacturing process.
Keysight Technologies, Inc. announced the release of
Quantum System Analysis, a breakthrough Electronic
Design Automation (EDA) solution that enables quantum
engineers to simulate and optimize quantum systems at
the system level.
