The appearance defect detection of electronic components is a very key link. Because such products are generally small and have high requirements for quality, it is difficult to pass the manual mass detection. It is necessary to use the visual detection equipment of electronic components for automatic appearance defect detection. The appearance equipment detection method can detect defects in real time, quickly and accurately identify scratches, greatly improve the production efficiency of the production line and improve the production quality of products.

Due to the lack of supervision system and the huge profits of fake goods, the phenomenon of making and selling fake products is more rampant, and more and more fake chips pour into the market. There are many high-level swindlers in the IC chip market. You know, the finished products produced by fake chips may bring significant income, health and safety problems. As a component distributor, we should maintain the market order, ensure the normalization of product channels and eliminate counterfeits. This paper collects and sorts out the relevant materials to distinguish the authenticity of fake detection chips. It is expected that this paper will have great reference value to all readers.

Since its birth, welding technology has played an important role in human production and life, and covers almost all industrial industries, such as construction, heavy industry, vehicles, ships, aerospace and so on. However, defects from the inside and outside of the weld will usually lead to welding failure, such as reduced welding strength, poor welding sealing, poor weld aesthetics, etc. Nondestructive testing has a wide range of applications. The development of core technology promotes the development of nondestructive testing equipment. Nowadays, nondestructive testing equipment has gradually changed from completely relying on import to independent research and development. The quality of domestic equipment is not inferior to that of import. Especially in some industries that require product accuracy, product quality is particularly important. View >>

There are many electronic components, such as resistors, capacitors, chips, diodes and triodes. Electronic components are also widely used, such as thyristors (thyristors), inductors, coils, transformers, crystal oscillators, headphones, resistors, capacitors, etc. Electronic product inspection is an essential means of quality monitoring in the production of modern electronic enterprises. It mainly plays the role of process control, quality control and judging the qualification of products. The following mainly introduces the relevant contents of quality inspection of electronic components. Let's have a look! View >>

The spring tide of core shortage continued, and several original factory price increases took effect around New Year's day, some of which were announced in the fourth quarter of last year, and some just announced. The price increase of these original factories just corresponds to the price increase of a new round of wafer foundry. This time, liandian "plays the most". In addition, the recent storage market is also variable due to the epidemic, but the impact is relatively limited compared with wafer foundry. View >>

Chip quality is mainly determined by three factors: market, performance and reliability. Firstly, in the early stage of chip development, it is necessary to fully investigate the market in order to define a spec that meets the needs of customers; The second is the performance. The circuit designed by the IC design engineer needs to pass designer simulation, DFT circuit verification, laboratory sample evaluation and FT before sample shipment to consider that the performance meets the requirements of the previous definition; Finally, reliability. Since the tested chip can only ensure that the customer is good when he first gets the sample, a series of stress tests are also required to simulate the impact of some harsh service conditions on the chip by the client, so as to evaluate the life of the chip and the possible quality risk.

As long as there is no problem in the design of general digital circuits, digital circuits are relatively stable. The most likely problems are those separate components, such as transistors and so on. Therefore, it is best to use more mature circuits and integrated circuit modules in the design, which will ensure the stability of the system. Aiming at the fault phenomenon of electronic products, we can deal with the faulty components through observation, hearing, feeling and touch, eliminating many unnecessary testing methods. If the above methods do not work, instruments and meters need to be used to test the suspicious components and related circuits to find out the fault point. When some components fail, the whole or some parts of the circuit will usually be shut down, making it unable to work, resulting in abnormal changes to electronic products. Therefore, the judgment and maintenance of component failure is a very important step. View >>
