Testing certification, testing the specified technical performance indexes of a certain object (gas, liquid and solid) by a specified method. Testing and certification covers a wide range. Each country has its own certification standards, which are applicable to the quality evaluation of various industries. No matter what kind of industry, the electronic household appliances used will face different regulations on the quality and safety certification of electronic products in various countries and regions. The following gives you examples of 13 common electronic product testing and certification related contents for your reference only. View >>

Now, with the progress of society, there are more and more electronic products on the market, and the detection of components is an essential basic work. After these electronic products are developed, how to accurately and effectively detect the relevant parameters of components must adopt different methods according to different components, so as to judge whether the components are normal or not. Only when the products are inspected and confirmed to meet the standards can they be launched. What are the inspection requirements and standards for electronic products? Let's have a look! View >>

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 >>
