Chip mainly refers to integrated circuit, also known as microcircuit, also known as microchip. Nowadays, chips have become indispensable to us. The essence of chip is semiconductor plus integrated circuit. It is a kind of micro circuit with special functions, which miniaturizes the circuit and makes it on a semiconductor wafer. Because the chip is small in size and does not occupy space in electronic products, it can make electronic products light and thin, and can also play a high performance and role. It can be said that a chip is like the heart or brain of an electronic device. It can not only carry out logic control, but also have computing ability. View >>

When testing the chip, pay attention not to cause a short circuit between the pins. The short circuit at any moment can be caught, resulting in the chip burning out. Failure analysis is an important part of chip testing. Whether for mass-produced samples, design links or customer returned products, failure analysis can help reduce costs and shorten the cycle.

PCB board is an important part of modern electronic equipment. Due to the small volume and high installation density of patch components, the integration of PCB board is required to be further improved. Attention should also be paid to details during testing, so as to better prepare and ensure product quality. Before PCB testing, understand the working environment of the equipment, mainly considering the possible impact of external electrical parameters on the equipment; Ask what happens when the circuit board fails, and analyze the causes of the failure; Carefully check the components on the circuit board to find out which components play a key role in the circuit board; Take anti electromagnetic, static and other interference measures.

Common IC failure modes: electrostatic damage, metal electromigration, chip bonding failure, over electric stress loss, metal fatigue, thermal stress, electromigration failure, physical damage failure, plastic packaging failure, lead bonding failure. When it comes to the causes of MLCC failure, under the normal use of the product, the root cause of failure is that there are various micro defects outside or inside the MLCC, such as cracking, holes, delamination and so on. These defects directly affect the electrical performance and reliability of MLCC products, and bring serious hidden dangers to product quality. View >>

The false soldering of components is that there are only a small number of tin welding posts at the solder joint, resulting in poor contact, on and off. Both false welding and false welding refer to that the surface of the weldment is not fully coated with tin, and the weldment is not fixed by tin. It is caused by the unclean surface of the weldment, too little flux and too short welding time. View >>

As the core component of electronic products, the performance of chip tends to be better and better. In order to ensure the quality of chip, people have adopted effective testing technology to test the function of chip. The main function of the chip is to complete the operation and processing tasks. Chip refers to the silicon chip containing integrated circuit. In the current process, in order to ensure the quality of the chip, chip detection is generally carried out in the process from design and molding to mass production. View >>

Reliability test refers to measuring and verifying the reliability of products through tests. The research finds out the weak links of products under the condition of limited samples, time and use cost. Reliability test is the general name of various tests carried out to understand, evaluate, analyze and improve the reliability of products. It is mainly to predict the quality of the product from the factory to the end of its service life. After selecting the environmental stress with high similarity to the market environment, set the degree and application time of environmental stress. The main purpose is to correctly evaluate the reliability of the product in a short time as possible. View >>

Circuit breaker refers to the switching device that can switch, carry and disconnect the current under the normal circuit state and disconnect the current under the abnormal circuit within the specified time. It can also be used to distribute electric energy, start asynchronous motor infrequently and protect power lines and motors, When they have serious overload, short circuit, undervoltage and other faults, they can automatically cut off the circuit. Their function is equivalent to the combined equipment of fuse switch and over and under heating relay. They are generally composed of contact system, arc extinguishing system, operating mechanism, release, shell, etc. View >>

The test to measure, verify or improve the reliability of products is called reliability test. It is an important link of product reliability. The quality inspection refers to whether the characteristics of the product are consistent with the specified standards, mainly considering the compliance. The reliability test is generally phased, while the quality inspection is routine. View >>
