PCB Connectivity

Training Center Classroom

Welcome to this installment of EE Classroom on PCB Connectivity.

More than ever, the humble connector has grabbed the spotlight in the IoT age of 75 billion connected devices by 2025. The expectation of connected small, light, and portable devices translates to miniaturization, thermal, and low-power challenges. From highly accurate data and power transmission to the incorporation of sensing and feedback integration requirements — all while working within the increasingly premium surface area of a PCB — requires you to expand your knowledge base as quickly and thoroughly as possible.

Let us help.

In this classroom, you’ll find answers to the “why”: why clean PCBs matter and why connectors fail. FAQs walk you through what you should consider when choosing RF interconnects from microwave to mmWave, and what role the various PCB materials play in optimizing applications from medical wearables to PCIe 4.0 and higher high-speed data channels. Designing with power, board-to-board, or wire-to-board connections? Get back to the basics with three extensive overviews from Engineers Garage. Sponsored solution guides provide valuable backgrounders and selection tables for FPC, lighting, high-speed, and infotainment applications.

There’s never been a better time to get even more connected with your connectors.

Microwave/Millimeter Wave interconnects

Signal integrity analysis of high-speed interconnects

Why do connectors fail?

Coaxial cables in mmwave application half the solution; the cable must be terminated with connectors.

The different approaches to channel diversity can be used individually or in combination.

Ideally, your connectors perform to their rated lifecycles. But why do they fail if they don't?

Why clean PCBs matter

Choosing PCB materials to optimize applications

As components get smaller, devices operating at high frequencies are more susceptible in many ways.

Repair of PCB assemblies can seem intimidating, but a methodical approach can help find and fix problems quickly..

Creating well-behaved PCBs is both a science and an art.

High-speed signals are the most likely to benefit from a detailed consideration of PCB materials

Compressible RF connectors

Besides giving birth to active devices, 5G has also spawned a need for connectors.
