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 >>

Definition of FMEA: FMEA is a quantitative analysis using bottom-up method. It can be implemented in the design or process. It identifies weaknesses in the design or process. It starts from the low level (component level) of the product or process to the failure of the system or subsystem. It highlights the key characteristics of the system or subsystem. The main purpose of FMEA is to identify the potential problems that may affect the safety and performance of the system or product in the early design process, and introduce countermeasures to reduce or minimize the impact of the identified potential problems (failure modes).

Nondestructive testing is a test method to check the surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. The purpose of nondestructive testing is to improve the manufacturing process, reduce the manufacturing cost, improve the possibility of products and ensure the safe operation of equipment. Any industry with large physical equipment or infrastructure may use some kind of non-destructive testing. Nondestructive testing has been widely used in many important industries around the world. Now mainly introduce its application scope and safety precautions. View >>
