Top 10 Beginner Mistakes in PCB Design

Top 10 Beginner Mistakes in PCB Design

Drawing a PCB isn't hard to get into, but it’s incredibly easy to make mistakes. Many people feel like they’ve mastered board design once they can import a schematic and generate Gerber files. But then the boards come back from fabrication—some whistling with noise, others suffering from interferenc

Does More PCB Layers Always Bring Better Signal Performance

Does More PCB Layers Always Bring Better Signal Performance

It is a common misconception that increasing PCB layer count unconditionally optimizes electrical signal quality, as multilayer stacking improves performance only when designed with rational stack-up rules instead of blind layer stacking. Extra PCB layers mainly provide dedicated ground and power re
