M & a small year to see more! The inventory of several "most" semiconductor mergers and acquisitions in 2021 came to an end in 2021. Generally speaking, last year was a small year for semiconductor mergers and acquisitions. Jibang consulting statistics pointed out that there were no mergers and acquisitions with a scale of more than US $10 billion last year, and several major mergers and acquisitions fluctuated around us $5-6 billion. But a small year does not mean poverty. After the tide of M & A around 2016 subsided, the M & A of semiconductor enterprises mainly completed the business sector and laid out emerging markets. Now let's take stock of those mergers and acquisitions last year. In addition, what unfinished mergers and acquisitions deserve attention. The most ambitious: ADI acquired Meixin. On August 26, 2021, ADI officially merged Meixin. This transaction is on the 20th View >>

High and low temperature alternating damp heat test refers to the adaptability test of products during storage, transportation and use under simulated test conditions of high temperature, low humidity, low temperature and high humidity and other different environments. The high temperature test in alternating damp heat test is aimed at the storage or use of products in indoor or confined space or near heat sources such as engine in high temperature season. The purpose is to test the adaptability of military and civil equipment to storage and work in high temperature environment. View >>

Because of the attack of automobile electrification, intelligence and networking, the global shortage of automobile chips and the rise of domestic automobile chip industry. The automotive chip industry has received unprecedented attention. The price of automotive electronic products is generally expensive. One of the main reasons is the use of vehicle specification electronic components, but what kind of electronic components are vehicle specification devices? View >>

Electronic components belong to industrial equipment, most of which can not be seen in daily life, because they are deployed in mobile phones, computers and intelligent devices. There are basically thousands of components. Different devices carry different functions, including high-tech RF equipment in addition to resistors and capacitors. There are many kinds of electronic components. The number of models involved in all kinds of electronic components is hundreds of millions. The market demand for electronic components is also very large, because electronic components have become an indispensable part in the industrial field. When we are not sure whether the quality of components is true or false, we can directly test the purchased electronic components. There are special testing institutions in China to help test the quality of components. View >>

Drop test is usually used to simulate the free drop that products may suffer during handling, and to investigate the ability of products to resist accidental impact, which is divided into packaging drop and bare metal drop. Bare metal drop mainly considers the ability of the product to resist accidental drop impact during normal use. Package drop can also reflect the protection ability of the package to the product when it is vertically dropped. Generally, the falling height is mostly based on the product weight and the possible falling probability as the reference standard. The falling surface should be a smooth and hard rigid surface made of concrete or steel (if there are special requirements, it should be determined by the product specification or customer test specification).

In recent years, the progress of science and technology makes the X-ray detection equipment used in production more strict. Crankshaft, cylinder, engine blade and other industrial parts also use castings. The production of castings is very easy to produce bubbles and other problems, which can not be solved by traditional technology. However, the nondestructive testing technology of X-ray testing equipment has obtained very accurate results in the testing of various castings, has a wide range of applications, and the technology is mature.

Generally speaking, the test conducted to evaluate and analyze the reliability of electronic products is called reliability test. It is to predict the quality from the delivery of products to the end of their 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 products in a short time as possible. View >>

Common reliability design principles and methods include component selection and control, thermal design, simplified design, derating design, redundancy and fault tolerance design, environmental protection design, robust design and human factor design. Except that component selection and control and thermal design are mainly used for reliability design of electronic products, other design principles and methods are applicable to reliability design of electronic products and mechanical products.

With the rapid development of chip design industry, a large number of chip types have been designed, but only a few of them will be large-scale streaming, and many chips are still in the design stage. This means that a large number of chip testing requirements have not been met. For a long time, the chip testing industry has been regarded as a part of chip packaging and testing. The real situation is that the traditional integrated sealing and testing enterprises are not enough to meet the current needs. View >>

With the development of the connector industry to today's level, you can start from many aspects to understand the quality of the connector. For example, among the three basic properties of the connector, the electrical performance belongs to the internal performance and the core of function play, while the mechanical performance and environmental performance can belong to the external performance.
