When a team selects SiC PCB, it is usually solving a specific product constraint rather than buying a label. This article takes a dfm view of silicon-carbide power devices and their copper or ceramic carrier interfaces. The project pain is commutation-loop inductance, heat-spreader stiffness, and the difference between a device rating and a board-leve l...

When a team selects SiC PCB, it is usually solving a specific product constraint rather than buying a label. This article takes a transition view of silicon-carbide power devices and their copper or ceramic carrier interfaces.

When a team selects SiC PCB, it is usually solving a specific product constraint rather than buying a label. This article takes a stackup view of silicon-carbide power devices and their copper or ceramic carrier interfaces. The project pain is commutation-loop inductance, heat-spreader stiffness, and the difference between a device rating and a board-level thermal...

A power amplifier module can have a favorable ceramic thermal value and still miss its temperature margin because the heat path is not released as a complete assembly. An Aluminum Nitride PCB shares heat and RF functions with copper, solder or braze, a carrier, and the enclosure. The project pain is usually an interface assumption:...
A high-power RF module can meet its electrical target and still fail in the field because the heat path was never released as a complete system. A Ceramic PCB changes the design conversation: the ceramic substrate, copper pattern, attach method, via or metallized interface, and the enclosure all share the same thermal boundary. The project...
Table of Contents Why thermal and RF paths interact Seven controls for stable power handling Heat path and copper balance Qualification and release evidence Engineering checklist A Duroid 6010 PCB can support compact microwave routing, but RF power and thermal design must be released together. The project pain point is the interaction between copper spreading,...
High-power microwave modules often fail at the thermal interface before they fail in the RF model. The finished RO5880 PCB must move heat away from the active device without disturbing the reference plane, launch geometry, or assembly datum. This engineering guide explains how to turn copper spreading and thermal-via decisions into a controlled design release...
What is a Microvia PCB? A Microvia PCB is a printed circuit board that uses very small vias—typically less than 150 microns in diameter—to connect adjacent layers. Unlike traditional through-hole or buried vias, microvias enable high-density routing and reduced signal path lengths, making them ideal for high-speed, high-performance, and compact electronic designs. Microvia technology is...
