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 ...

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 ...

In-circuit test (ICT) has been instrumental in identifying manufacturing process defects and component defects on countless varieties of populated printed circuit board (PCB) assemblies for more than ...

Change in life is inevitable. You know this, yet sometimes you just choose not to accept it. You just close your eyes and think the world has also stopped. But even you realize that’s not the case. It ...

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 ...
