Testing a circuit breaker is about judging reliability under fault conditions, not just checking continuity or voltage. A ...

Production test of a finished electronic product often involves two techniques: in-circuit test (ICT) and functional component test (FCT). The ICT technique examines a non-powered circuit board to ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Why are test points a crucial element in developing a successful circuit? Types of test points available, and the different techniques that employ them. Electronic design has always been an endeavor ...

So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...

Every year, we read about electricians, engineers, and supervisors who were seriously burned or killed while working in or near a circuit breaker (CB) compartment. I’ve personally investigated ...

Printed-circuit boards used to be works of art, and the PCB designer was an artist as well as a technician. Components had many different shapes, sizes, and colors, and the traces connecting them were ...

Ground Fault Circuit Interrupter outlets quietly guard the most dangerous spots in your home, cutting power in a fraction of ...

Test is becoming increasingly complicated as new technologies such as flexible electronics begin playing mission-critical roles in applications where electronics have little or no history. Although ...
