Hello, Welcome to the Altium Learning Hub

The IPC-2221 standard includes many requirements for printed circuit board design and manufacturability, and there are several online calculators that have been developed based on this standard. Aside from impedance and annular ring calculations, one of the other major formulas specified in this standard relates temperature rise, trace width, and trace current. The IPC-2221 standard and IPC-2152 standard both include this guidance on designing...

Stitching vias are something you often see spread around the surface layer of a PCB. If someone is using copper pour correctly, then they will ideally calculate an appropriate stitching via separation distance such that the via array suppresses crosstalk/interference. The other option is usage as multiple parallel connections between layers that can provide low resistance and impedance, and therefore they can provide high current in DC or AC. In...

Get ready to speed up your design process with new Altium Designer collaboration capabilities. Designing a PCB is a team effort. Engineers must work with customers, manufacturers, and other stakeholders to get the best results. You need help to bring your design to life, even if you're a one-person team. Join us this month's webinar, where we'll discuss what's new in Altium Designer 23, focusing on how you can collaborate like a pro. This...

If you’ve taken time to learn about PCB material options and layer constructions, you have probably seen the wide range of materials that are available on the market. Materials companies produce laminates with varying Dk values, Tg values, weave styles, CTI values, and mechanical properties to target various applications in the electronics industry. There is one set of materials that gets a lot of attention for its low-loss behavior: low-Dk PCB...

If you’re waiting for truly connected cars on a grand scale, there is still a massive amount of work to be done, both on the hardware and software sides. Connected cars can only become a widespread reality once the automotive industry and telecom carriers can decide which protocol will work best for vehicle-to-everything (V2X) communication. PCB designers will then need to step in to create these systems and fit them into a vehicular environment...

In Getting Started with MicroPython and the Raspberry Pi Pico we looked at how to set up, configure, and run MicroPython on a Raspberry Pi Pico device. In this article we will be focusing on automating that process and turning it into a Continuous Integration (CI) pipeline. Moving the automation into CI will guarantee that our code gets tested every time we push a commit to our code repository Automating MicroPython Commands and Development N...
