A practical engineering guide to spine-leaf data center fabrics: how every leaf connects to every spine, why the design replaced the three-tier network, how to size oversubscription and port counts, and which routing, cabling, and optics choices follow from it.
This guide covers what it applies to, how it differs from UL 508, how Supplement SB establishes the short-circuit current rating for a panel, and what it actually takes to label a panel under the UL 508A panel shop program.
Controlled impedance is the control of PCB trace impedance within specified tolerances. This article covers microstrip and stripline designs, IPC-2141A formulas, stackup selection, impedance tolerances, routing practices, and TDR testing for signal integrity.
A PCB design can be electrically correct, pass every design rule check and perform exactly as expected on an engineer's screen - and still cause significant problems when it reaches manufacturing.
The motor control center puts the starters, protection and controls for many electric motors into one lineup of cabinets. This guide explains what it is, how it is built, how it differs from switchgear and a VFD, and what current standards expect for safety and maintenance.
A semiconductor is a material whose electrical conductivity falls between that of a conductor and an insulator and can be controlled by temperature, light, and impurities. This article covers semiconductor materials, doping, diodes, transistors, and integrated circuits.
