Core of Power Layout for Multilayer PCBs: How Layered Design Solves Noise and Heat Issues

When a prototype power board is powered on for the first time, the best-case scenario is that it not only works but also operates quietly and with low heat generation. However, this situation is rare. A common issue with switch-mode power supplies is the “unstable” switching waveform, where waveform jitter falls within the acoustic range, … Read more

From Layer Stacking to Signal Integrity: Key Principles of PCB Multilayer Design for Beginners

In the production of high multilayer PCBs, the drilling process directly determines the yield and reliability of the product. Industry data shows that the scrap rate of PCBs due to unreasonable hole diameter design can be as high as 30%, with poor hole processing in high multilayer boards accounting for over 45%. This article strictly … Read more
