The NCP51820 is a 650 V, high-speed, half-bridge driver capable of driving gallium nitride (GaN) power switches at dV/dt rates up to 200 V/ns. Previously, we briefly introduced an overview of PCB design strategies for GaN drivers. This article will focus on the PCB design considerations that must be taken into account when designing high-performance…

1.What is ESD? ESD stands for electrostatic discharge. Many materials can conduct electricity and accumulate charge. ESD occurs due to triboelectric charging (friction between materials) or electrostatic induction. Whenever this happens, an object forms a fixed charge (static electricity) on its surface. When this object is placed too close to another charged object or material,…

In the field of electronic products, PCB (Printed Circuit Board) is an extremely critical component. Whether it is a high-speed circuit, a high-frequency circuit or a millimeter-wave related product, it is indispensable. The processing of PCB boards is a complex system engineering, covering multiple aspects such as PCB materials, potions, processing technology and line geometry…

Why can’t the signal line change holes multiple times in high-speed PCB design? Everyone must have come into contact with vias when designing PCBs, so everyone knows that vias have a great impact on the quality of PCB signals. Let me first introduce to you how to select vias when designing PCBs. 8/16±2mil 10/20±2mil 12/24±2mil…
