In the ever-evolving electronics landscape, rigid-flex PCBs are a game-changer in wearable devices and IoT sensors. By eliminating the need for bulky connectors and cables, rigid-flex PCBs allow designers to pack more functionality into smaller form factors. Additionally, the ability to withstand mechanical stress and vibration makes rigid-flex constructions well-suited for r...

Sierra Circuits manufactured and assembled a two-board PCB system designed using Quilter AI. The project, called Speedrun, consists of a system-on-module (SOM) and a baseboard built around the NXP i.MX 8M Mini processor. 

Since the layouts were generated rapidly using automation, our team performed DFM, DFA, and CAM reviews to&nb...

High-power PCBs fail when current-induced heating, voltage stress, and mechanical strain exceed the design limits. These problems are often caused by poor design decisions, including layout planning, stack-up, and thermal management. This can lead to overheating and long-term structural damage.

Board designers and power ele...

PCB material OEMs such as Isola, Rogers, and DuPont develop laminates optimized for specific electrical and mechanical requirements.

These laminates are grouped into different substrate families (FR4, polyimide, PTFE) based on their resin system, dielectric performance, and intended application. Understanding the strengths of different OEMs and dielectric families help...

Designing a reliable aerospace PCB starts with applying the right layout and thermal management strategies to handle extreme operating conditions.

Layout engineers and hardware designers must select high-reliability laminates, heavy copper constructions, and components that meet the mechanical, thermal, and electrical demands.

In this article, you’ll learn pract...
