Circuit Board Design

FR4 Dielectric Constant and Material Properties Wondering what is FR4? FR4 is by far the most popular set of PCB substrate materials. Here is how FR4 dielectric constant and your material properties will affect your next PCB. Read Article

Transmission Line and PCB Track Design

Transmission Lines in PCB Track Design Digital designs fall broadly into two categories: low-speed and high-speed. The category “high speed” does not necessarily mean a high clock rate. Rather, it refers to the rise time of the signal during switching, which leads to propagating wave behavior on long PCB tracks. When a PCB track gets too long, it needs to be designed like a transmission line, not just a simple conductor with DC resistance. Understanding how to design transmission Read Article

How to Find the Transistor Parts You Need for Your Circuit Board

How to Find the Transistor PCB Parts You Need for Your Circuit Board Design Transistors are vital components in power supplies, high-power ICs, and embedded systems, enabling efficient switching in electronics, sensors, and analog systems.

PCB Relay Selection, Design, and Layout are Easy in Altium Designer

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 Read Article

Spot Copper Connection Errors in Design Rule Checks

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 Read Article

Design RF PCBs With a Coplanar Waveguide Calculator

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 Read Article

Build Your Next LED PCB Design in Altium's Unified Environment

Build Your Next LED PCB Design in Altium's Unified Environment LED driver boards can be challenging designs when running at high power and high voltage. Power systems for driving devices like LED panels need careful planning and layout for power supply sections, and the LED PCB board design itself needs to be laid out to ensure low-temperature operation. These objectives can be difficult to balance without the best PCB LED circuit design software features and DC analysis tools. When you need to create a high Read Article
