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 ...

The importance of properly integrating test points into a PCB design. Test-point deployment considerations. When it comes to creating a modern electronic design, we live in both the best and the worst ...

Modern printed circuit board assemblies (PCBAs) are designed to support increasingly complex applications in industries such as telecommunications, automotive, consumer electronics, and industrial ...

This is a simple circuit which checks the polarity of the component. If you connected in right polarity the LED in the circuit will glow and it will not glow when you connected in wrong way. This is a ...

What is Non-Destructive Testing? Nondestructive testing is a means of evaluating a material or component’s superficial or interior defects or mechanical conditions without compromising the component ...

In-circuit test (ICT) is a time-tested and proven method of testing PCBs. During ICT, a bed-of-nails fixture provides test-instrument access to PCB nodes. Each nail is positioned such that, when the ...

A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V.

In the process of being conceived, prototyped, and readied for final production, a medical device is turned over to regulatory experts or knowledgeable team members in order to undergo regulatory ...
