A large number of various types of electronic components are used in electronic equipment. Most of the equipment failures are caused by the failure or damage of electronic components. Failure analysis plays an important role in ensuring and improving the reliability and quality of products. Failure analysis needs to be introduced in product R & D, production and use. The following are some relevant contents of failure detection and sorting of common electronic components for your reference. View >>

Voice chip is an integrated circuit that can store, control and play voice. It is called speech IC in English. It is an integrated circuit chip with built-in small storage space, 1mbit-4mbit and storage time of 40-160 seconds. It can be controlled by keys or MCU. It is also to convert the voice signal into digital signal through sampling, store it in the ROM of the integrated circuit, and then restore the digital voice signal in the ROM through the circuit. From the meaning of the name, it can be seen that it is a function of adding voice on the basis of electronic products, that is, the input voice is processed through the chip and played out through the speaker.

There are many methods of chip burning. In large-scale production, it is still based on burner burning. If you use a burner to burn, you have to use the burning base. The usage times of each burning base can not be effectively monitored. Once the service life of the burning base is exceeded, there is no way to ensure the burning quality of the chip. The burning base does not have the function of detecting whether the burning base matches the chip to be burned, so how to detect whether the chip can be burned? View >>

With the development of electronic technology, the demand for chips is increasing. In order to improve the production efficiency, multi station IC chip burning technology has been widely used. As a kind of processor, burning chip needs a program to miniaturize all components into one or several integrated circuits; An integrated circuit that can receive coding instructions at one or more ends, execute the instructions and output signals describing its state, and the process of storing programs in the chip is called chip burning.

Nowadays, due to the damage of an integrated circuit, some or several parts of electronic products can not work often, which affects the normal use of equipment. So how to detect the quality of integrated circuits? The detection methods of integrated circuits mainly include visual method, sensory method, voltage detection method, resistance detection method, current detection method, signal injection method, substitution method, heating and cooling method, step-up or step-down method and comprehensive method.

In recent years, with the rise of all kinds of intelligent terminal equipment, the quality requirements of electronic products are higher and higher. However, with the continuous influx of various fake and shoddy products into the market, it has an adverse impact on consumers and market reputation. Although the regulatory authorities and market electronic products continue to strengthen supervision, it is still impossible to avoid counterfeit goods. As the core component of electronic products, in order to ensure the quality of chips, manufacturers have adopted effective X-ray nondestructive testing technology for chip testing. View >>

Failure analysis is a newly developed discipline, which has strong practical significance in improving product quality, technology development, improvement, product repair and arbitration of failure accidents. Comprehensive and systematic failure analysis can determine the cause of failure, guide the improvement of device design, manufacturing process, test or application, and take corresponding corrective measures to eliminate the cause of failure mode or mechanism, so as to improve the overall reliability of devices and equipment.

Component unsealing, also known as component cover opening and cap opening, is a commonly used destructive detection method in failure analysis. Generally speaking, that is to do surgery on the chip. Through unsealing, we can intuitively observe the internal structure of the chip. After unsealing, we can judge the current situation and possible causes of the sample in combination with OM analysis. View >>

Since each functional element has its own test requirements, the design engineer must make test planning at the early stage of design. Chip is the product of modern top high-tech technology. Chip exists in a variety of electronic products. The high integration of chip also makes the chip have more and more powerful functions. What tests does the chip need to do? It is mainly divided into three categories: chip function test, performance test and reliability test. The three tests for chip products to be listed are indispensable. View >>

Acetone, also known as dimethyl ketone, is the simplest saturated ketone. It is a colorless transparent liquid with a special pungent smell. It is easily soluble in water and organic solvents such as methanol, chloroform, ethanol, ether and pyridine. It is flammable, volatile and has active chemical properties. At present, the industrial production of acetone in the world is mainly based on cumene method. Acetone is mainly used as solvent in industry in industries such as explosives, rubber, tanning, plastics, grease, fiber and painting. It can also be used as synthetic ketene, acetic anhydride, iodoform Polyisoprene rubber, methacrylic acid, methyl ester, chloroform, epoxy resin and other important raw materials. View >>
