Hello, Welcome to the Altium Learning Hub

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...

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...

How often have you started down the PCB development process and been bogged down by time-consuming administrative tasks? Once you get ready for production, working through a design review and correcting any DFM problems takes its own share of time. With hastening product development timelines and shorter product life cycles comes the pressure to increase PCB prototype iteration speed without sacrificing cost or quality. So how can PCB design tea...

The week of October 5, 2020, was a whirlwind thanks in part to the annual holding of AltiumLive. I did my best to attend some sessions at AltiumLive, but there were at least three other critical conferences I was invited to attend or present at, and I couldn’t hit them all. The other events of the week included: Conference on Electrical Performance of Electronic Packaging and Systems (EPEPS), presented by IEEE Electronics Packaging Society Elec...

I’ll be honest, I still use an MP3 player with a 32 GB microSD card. I go running most days, and the last thing I need is to drop my phone in the street and watch the screen shatter, thus the $15 MP3 player. This also means that I need a USB-microSD card reader in order to switch out music on my memory card. These cards aren’t limited to use in MP3 players, they also provide add-on memory for single-board computers like the Raspberry Pi...

There are many different Arduino boards available for development and prototyping, and you might consider designing your own Arduino PCB schematic. If you want to modify an Arduino Mega schematic, you need design software that lets you easily build around an Arduino board and quickly add functionality. Your design software should make it easy to use any Arduino mega pinout board, like the Arduino Uno PCB schematic, Mega, Zero, or another model...

When designing circuit boards, there are some functions that your PCB (printed circuit board) design tools must excel at without exception. These include the basic functions of schematic design, schematic capture, placing parts, and routing traces. There are other important functions you won’t find in free PCB design software. These include bill of materials compilation, generation of Gerbers and other deliverables, and data management functions...

Key Takeaways: Unified Workflow: Modern hardware development requires moving seamlessly from schematic capture to PCB layout without losing data. Simulation First: Running signal integrity simulation and power supply simulation during layout prevents costly respins. Collaboration: Real-time ECAD MCAD integration is not optional; it's required to fit complex boards into tight enclosures. Circuit CAD Software for PCB Design Hardware is hard...

Handling the ever-growing complexities of today’s routing demands requires board layout software that can keep up. When yesterday’s tools are no longer getting the job done, get back on the road of productive design today with the most powerful easy draw PCB design layout software. When you need powerful board layout software, you need to easily complete the following tasks: Visually and easily manage your PCB copper pours Peace of mind PCB...
