After the critical circuits, we like to examine the printed-circuit board (PCB) stackup. Like the schematic, board stackup decisions are often made prior to routing and placement, so this is a good ...

Last, but not least, we like to look at the I/O (Input/Output) circuits during EMI circuit board reviews. As a port of entry for external currents, I/O circuits are particularly vulnerable to threats ...

The requirements for masts as supports differ from previous NEC versions. Have you kept up with Code rule changes? Do you know what changed here? Previously, Sec. 225 ...

Most every device and electronic piece of equipment is outfitted with a printed circuit board (PCB), including smartphones, TVs, appliances, and more. You know the composite. The boards are laminated ...

Series Circuit Calculations provides a comprehensive overview of the rules and formulas used to calculate and predict electrical quantities and capacity. Using a direct current (DC) series circuit as ...

What about installing lighting equipment outdoors? You can find these requirements in Sec. 225.7 of the NEC. The first requirement is that the branch circuits must comply with Art. 210, which covers ...
