Designing for Multiple PCBs in the Same Project Majority of our PCB designs sit as a single PCB under our Altium Designer projects (i.e. .PrjPcb file). Now and then, we design using variants with different stuffing options. It seldom happens that we have a single project that requires multiple PCBs with various stuffing options, but when it happens, a lot of us tend to get stuck. All too many times, I have seen designers fork (i.e., copy and paste) a project and then add slight variations to Read Article

Leveraging the Free Footprint Community to Design at Lightning Speed One of the biggest hurdles individuals and startups face with creating new PCB designs is footprint creation. Designing footprints is a job most people hate. It’s tedious, time consuming, and doesn’t result in much except, well, a footprint. Companies now realize this pain point and offering designers free, well-designed PCB footprints. Why would they spend their time doing this? Imagine Company A sells a connector for $5.00, but no footprint is Read Article

Designing 5G Devices The next stage in the evolution of mobile telephony is here with the roll-out of 5G. The designer looking to incorporate functionality to handle 5G signals into their circuits will face some challenging issues. So, what’s so special about 5G. The main change in the jump from 4G to 5G is the frequency band at which signals are transmitted. For 4G, this band covered 0.7 GHz up to 2.5 GHz. For 5G, this new band is an order of magnitude larger, with Read Article
