A large number of various types of electronic components are used in electronic equipment. The failure of electrical equipment is mostly caused by the damage of components. The failure of electronic equipment caused by other reasons often leads to the damage of electronic components, resulting in the failure of equipment. Therefore, the detection of components is an essential basic work. How to accurately and effectively detect the relevant parameters of components and judge whether the components are normal is not a stereotype. Different methods must be adopted according to different components to judge whether the components are normal or not. The following is the experience sharing of common electronic component testing methods for your reference. View >>

In the second quarter, chip shortage and price rise continued. In April, many chip manufacturers at home and abroad successively sent letters to raise prices and suspend orders. At the same time, wafer foundry also began a new round of price increases. Various signs show that the shortage of chips and the rise in prices are bound to reach a new height. The market in the "post epidemic era" is destined to be extraordinary. View >>

The quality of the inductor can be detected with a multimeter. As shown in the figure, place the multimeter in "R" × 1 "gear, the two probes (regardless of positive and negative) are connected with the two pins of the inductor, the indication of the probe should be close to" 0 Ω ", and the inductor with large inductance should have a certain resistance value. If the needle does not move, it indicates that the inductor is internally open; If the indication of the gauge needle is unstable, it indicates poor internal contact. View >>

Capacitance (or capacitance) refers to the charge storage under a given potential difference; Marked as C, the international unit is farad (f). Generally speaking, the charge will move under force in the electric field. When there is a medium between the conductors, it hinders the charge movement and makes the charge accumulate on the conductor; The most common example of cumulative charge storage is two parallel metal plates. It is also commonly known as capacitor. View >>

As a worker in the electronics industry, resistance is well known. There is no doubt about its importance. It is said that "resistance is the most used component in all electronic circuits." Resistance, because the substance hinders the current, it is called the resistive substance under this action. Resistance will lead to the change of electron flow. The smaller the resistance, the greater the electron flow, and vice versa. A substance with no or little resistance is called an electrical conductor, or conductor for short. View >>
