Why No Traces Under a Crystal Oscillator in PCB Layout?
When designing a PCB, many engineers have heard the rule: no traces should run under a crystal oscillator. But why? Can a low-speed signal trace really affect a crystal oscillator? And can a guard rin...

PCB Routing Angle Rules and the 90 Degree Trace Myth
In the realm of hardware design, "never use 90° angle traces" is one of the most widely circulated rules. Most engineers habitually modify 90° corners into 45° bends, or even intentionally increase tr...
