Crystal oscillator is widely used in electronic equipment and intelligent control system. Each single-chip microcomputer system has a crystal oscillator. The whole process is called a crystal oscillator. In the single-chip microcomputer system, the crystal oscillator plays a very important role. It combines the internal circuit of the single-chip microcomputer to generate the necessary clock frequency of the single-chip microcomputer. The execution of all instructions of the single-chip microcomputer is based on this. The higher the clock frequency provided by the crystal oscillator, the faster the running speed of the single-chip microcomputer. View >>

Diode faults are mainly manifested in open circuit, short circuit and unstable voltage stabilization. Among the three faults, the former one shows the increase of power supply voltage; The latter fault shows that the power supply voltage becomes low to zero volts or the output is unstable. How to check and judge the diode? Below, Chuangxin online testing organization will share the testing experience of electronic components. Let's have a look! View >>

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 >>
