Impedance Control PCB

Blog cover illustrating a choice between a standard low-speed PCB and a high-speed PCB with highlighted controlled-impedance differential pairs.

Do You Really Need Controlled Impedance for Your PCB Design?

PCB Design Tips / By

Wondering if your next board really needs controlled impedance or if standard fabrication is enough? This article walks through the key factors that drive the decision – signal speed, trace length, interface standards, product criticality and cost – and outlines practical cases where controlled impedance is essential, where it is optional and how to choose the right level of impedance control together with your PCB manufacturer.

How PCB Manufacturers Use TDR and Coupons to Verify Controlled Impedance

PCB Manufacturing Insights / By

Specifying controlled impedance is only half the job – you also need to verify it. This article explains what PCB impedance coupons are, how manufacturers use Time Domain Reflectometry (TDR) to measure them, how to read a TDR report and when it makes sense to request coupons and testing for your high‑speed and RF boards.

Blog cover showing a multilayer PCB stackup and controlled impedance traces for a high-speed stackup design guide.

PCB Impedance Control Stackup Design Guide for High‑Speed Signals

PCB Design Tips / By

A good stackup is the foundation of any impedance‑controlled PCB. This guide explains the key parameters that shape trace impedance, compares common microstrip and stripline structures, walks through example stackups for high‑speed designs and shows how to collaborate with your PCB manufacturer to turn your impedance targets into a manufacturable, reliable board.

How to Specify Controlled Impedance Requirements to Your PCB Manufacturer

PCB Manufacturing Insights / By

Clear controlled impedance requirements can make the difference between a smooth PCB fabrication run and weeks of delays and redesigns. This guide explains what information your PCB manufacturer really needs – from target impedance and stackup details to documentation, coupons and TDR reports – so your high‑speed boards get built right the first time.
