PCB Relay Selection, Design, and Layout are Easy in Altium Designer
Circuit protection is vital for user safety and for protecting a board from electrical damage. Whether you’re working with a small, moderate power PCB or a large, high voltage electromechanical system, power surges or faults can destroy components and create hazards for users. The best way to ensure your next device remains safe from high voltage ESD or large current surges is to use a simple PCB relay. Compared to large relays that need to be

Copper Connection Software: Instantly Check Every Connection With Rules-Driven PCB Design Tools
It’s easy to find errors in most simple PCBs. Simply scan through your critical nets and trace each copper connection from source to load. Today’s printed circuit boards are not so easy to inspect and validate by eye. Even relatively simple low-speed boards can have hundreds of components packed into a small space, and it’s easy to get lost in a complex PCB layout. Today’s modern designs demand modern design tools. Altium Designer users have

Design RF PCBs With a Coplanar Waveguide Calculator
RF PCBs can be complex boards that need careful interconnect design and layout. If you’re designing an RF PCB for microwave or higher frequencies, controlled impedance routing should be top of mind to ensure signal integrity. You can choose from many routing styles, but whichever routing style you choose, it should provide isolation against noise and crosstalk. A coplanar waveguide routing style is an excellent choice for RF PCBs as they can be

The Best High Voltage PCB Design Software Package
Of all the different boards a designer can create, a high voltage PCB design can be complicated and requires strict attention to safety. If not laid out correctly these boards can be safety hazards or can fail to function on first power up, leaving a designer with wasted time and effort. In the best case, the board will function reliably for a long period of time thanks to correct layout practices. When you’re planning your next high voltage PCB

Making the Most of Your Crystal Oscillator
“Blindly” adopting what a crystal oscillator data sheet says usually results in adequate frequency stability. An oscillator requires the phase shift around the loop to be 360° and this total phase shift must be a precise and stable oscillation frequency.

How to Use Thermocouples in Your Next Project
Thermocouples are the final sensor type in a series where we look at all the main types of temperature sensors you might use in an electronics project. In this series, we have looked at the various ways to implement different temperature sensors in your project. At the end of the series, we’ll be putting the sensors and implementations in a head to head competition using real-world conditions. Through this real-world testing, will gain a better

Include IC Pin Numbers in Your Altium Designer Parts Data
When you create components, you’ll really be creating 3 different CAD models: a schematic symbol, PCB footprint, and 3D model. Integrated circuits need multiple pieces of information, including courtyards, IC pin numbers, designators, and electrical simulation models to be most effective in your PCB design and analysis tools. If you’re working with most CAD tools, you won’t have the features you need to perform all of these tasks. Enter Altium

Adding Arduino Boards to Your Integrated Components Libraries
An Arduino board is a great way to include standard functionality in your next PCB. If you want to use an Arduino board in your PCB design software, you’ll need to include Arduino boards as part of your component libraries. This allows you to incorporate Arduino boards into your electronics schematics, layouts, and bills of materials. You can use Arduino boards as the backbone for your next product, or as part of a larger multi-board system

Crosstalk or Coupling
The words crosstalk and coupling are used to describe the injection of electromagnetic energy from one transmission line to another running nearby. In printed circuit boards crosstalk is usually two traces running side by side in the same layer or one over the top of the other in adjacent layers. This coupled energy appears as noise on the victim trace and can cause malfunctions if the amplitude is too large. Learn how this noise is transferred

Transmission Line Termination Techniques in High-Speed Design
A transmission line is a pair of conductors used to deliver energy in the form of an electromagnetic field. Most of us are familiar with the wires that lead to our houses delivering the power needed to operate our lights and appliances. In the context of PCB design, it is a signal in a signal layer on top of a plane or between two planes. TRANSMISSION LINE TERMINATION TECHNIQUES FOR PCB DESIGN The purpose of this section is to explain what
