Generally, there will be specifications on the IC, that is, IC datasheet. The datasheet will generally indicate whether the IC is an OTP component. OTP itself is also the abbreviation of one time programmable. One time means one-time and programmable means burning. If it is not a new material, first remove the old program in the original IC. After removal, you also need to check whether the program has been cleared, whether it is empty or not, and then burn it again. Burning is to program data and programs into IC. After burning, we also need to check whether the IC burned is correct, and then do encryption or write protection. View >>

At present, many electronic product manufacturers specially polish the printing on the surface of one or more IC models in their products in order not to let others know the IC chip models used in their products. The model of computer chips can also be determined through the detection of drivers and third-party software, but computer chips are rarely polished in the main board factory. So how to detect the model after the chip is polished? In order to provide you with more knowledge about IC models, let me introduce you to the following related contents. View >>

When it comes to chips, we all know that this is a very high-tech and professional field, and the whole production process is particularly complex. Goods on the market generally go through three stages: design, manufacturing and packaging. Integrated circuit chip is an integrated circuit formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) on a plastic base to make a chip. IC chip includes wafer chip and packaging chip. The corresponding IC chip production line is composed of wafer production line and packaging production line. How to distinguish between true and false IC products? Let's introduce it to you. View >>

Electronic component testing is the application of testing service industry technology in electronic information industry. It is an important link in the specific industrial chain of electronic components. The level of testing service technology is closely related to the quality of electronic components. Electronic technology is an emerging technology developed at the end of the 19th century and the beginning of the 20th century. It has developed most rapidly and widely used in the 20th century, and has become an important symbol of the development of modern science and technology. How to accurately and effectively detect the relevant parameters of components and identify the quality of components must adopt different methods according to different components, so as to judge whether the components can work normally.

Ceramic capacitors are made of high dielectric constant capacitor ceramics extruded into circular tubes, discs or disks as the medium, and silver is plated on the ceramics as the electrode by sintering infiltration method. The capacitor with small positive capacitance temperature coefficient is used in high stable oscillation circuit as loop capacitor and padding capacitor. Ceramic capacitors are easy to fail when used in inappropriate circuits. View >>

Varistor is a voltage limiting protection device. Using the nonlinear characteristics of varistor, when overvoltage occurs at its two poles, varistor can clamp the voltage to a relatively fixed voltage value, so as to protect the subsequent circuit. Varistors also play a very important role in transient overvoltage protection in circuits. Although its flow capacity is large, its energy capacity is not large. In addition, because its impulse current pulse width is far less than the actual pulse current width of large and medium-sized power semiconductor systems, short circuit, burnout and failure often occur.

The key work of electronic product development is the design of principle realization, component (material) selection, verification and testing, etc. Incoming inspection of components is a very important part and the source of quality management. As the saying goes, "everything is difficult at the beginning". Therefore, only by controlling the source, the subsequent production will be relatively easy. Select appropriate suppliers according to the function and processing technology of product parts to ensure the quality of parts and save costs. View >>

In the process of PCBA processing, in order to enable the PCB board to realize some specific functions, in addition to the hardware, there is also software, which needs to add the program of "burning" in the PCBA processing process, that is, to "carry" the program into the IC. Before starting "burning", we should test whether the PCB board is qualified, and then select the appropriate burning method. View >>

Fracture analysis is a subject of studying metal fracture surface and an integral part of fracture subject. A pair of mutually matched fracture surfaces and their appearance obtained after metal fracture are called fracture. Metal fracture is a common identification item in quality identification. Through the analysis of fracture, we can help us make a comprehensive analysis of the quality of electronic products. So what are the fracture analysis methods for testing metal materials? View >>
