We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Diodes whose reverse-breakdown characteristics are controlled precisely during manufacture are called as Zener diodes and are intended specifically for operation in the reverse breakdown mode ...

Tiny light-emitting diodes with optical microsystems that can produce all the colors of the rainbow ... a new method for producing printed circuit boards. These are some of the innovative developments ...

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 polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...
