Why Does the Circuit Board Make a 'Ticking' Sound?

After the delivery of a previous design project, due to an operational error by the on-site debugging personnel, the exposed wire ends touched the circuit board (which was coated with a conformal coating) when the rear panel of the device was removed, ultimately causing a short circuit. The feedback from the site indicated that the … Read more

Why Do Circuit Boards Require So Many Resistors, Capacitors, Inductors, and Other Electronic Components?

Learning about electronics can be confusing due to the thousands of models of electronic components available. How can one remember them all? Why are so many electronic components necessary?Why are there so many different resistor values, various capacitor capacities, and different sizes of inductors? There are numerous types of transistors and different models of integrated … Read more
