Impedance Matching in HDI PCB Design

Impedance Matching in HDI PCB Design

Impedance matching is the way of configuring the input impedance of a load or the output impedance of its signal source. It is performed to achieve maximum power transfer and reduce the signal reflections from the load. In other words, for proper impedance control,...

Controlled Impedance Routing Using Altium Designer

Controlled Impedance Routing Using Altium Designer

Controlled impedance is the characteristic impedance of a transmission line formed by PCB traces and its associated reference planes. It is relevant when high-frequency signals are propagating on the PCB transmission line.  In this article, we will demonstrate...

How to Control your Controlled Impedance

How to Control your Controlled Impedance

While manufacturing a PCB, controlled impedance can be achieved through specific dielectric thickness and by providing the target ohms on each layer. The factors that influence impedance are the PCB materials’ dielectric, the trace thickness, width, and height from...

Why Controlled Impedance Really Matters?

Why Controlled Impedance Really Matters?

Every day, PCB designs and components become smaller, faster – in other words, more complicated. It is now crucial to understand your critical nets and traces, impedances, and how the board impacts the performance of the signal. The time of simple interconnecting...

What is Signal Propagation Delay in a PCB?

What is Signal Propagation Delay in a PCB?

Delay is frustrating, whether in our daily lives or the devices we use for our convenience. Propagation delay/time delay inhibits the intended functions of the devices. When I say ‘devices,’ I am trying to draw your attention towards the components responsible for a...

7 Tips and PCB Design Guidelines for EMI and EMC

Electromagnetic interference (EMI) is associated with every electronic device we use nowadays. If you turn on your radio set and TV simultaneously, you will experience the noisy disturbance from TV interfering with the radio signal and vice-versa. We can also...
