Where fast, dense designs get hard.

At high speeds and high power, wires stop behaving like simple connections. These disciplines keep complex boards working.

1. 1Signal integrityWhen a trace stops being a wire: reflections, ringing, crosstalk and termination, and the rise time that decides whether any of it matters.1 min read·2 questions
2. 2Controlled impedance & high-speed designGeometry sets impedance. Microstrip and stripline, 50 Ω and 90 Ω differential, length matching, and what a real stackup does to your targets.1 min read·3 questions
3. 3EMC, EMI & RF basicsEmissions and susceptibility, why loop area and edge rates dominate both, and the layout habits that get a board through a compliance lab.1 min read·2 questions
4. 4Thermal management & power integrityWhere the heat goes and whether the rail holds. Thermal resistance, copper as a heatsink, thermal vias, and PDN impedance across frequency.2 min read·2 questions
