Since the epidemic, the tide of core shortage has intensified, and the prices of out of stock have been increasing. Major chip foundry and IDM manufacturers have identified the opportunity to expand production. All factories aim at the most scarce mature process chips, including vehicle chips, MCU and various drive ICs. View >>

Reliability test can generally be divided into engineering test and statistical test. The purpose of engineering test is to expose the defects, weak links and faults of products in design, process, components and raw materials, so as to provide information for improving product reliability. The purpose of statistical test is to verify whether the product meets the specified reliability or service life requirements. The following is a list of common military and civilian product reliability test standards, which I hope will be helpful to you. View >>

Nowadays, there are many kinds of products that need reliability testing. Through reliability testing, we can determine the reliability characteristics of electronic products when they work or store under various environmental conditions, so as to provide useful data for use, production and design; It can also expose the problems existing in the design, raw materials and process flow of the product. Since enterprises have different testing requirements according to different needs, what reliability testing items need to be tested in most cases of electronic components? Let's take a look.

What is the ROHS test report? RoHS is a chemical report. RoHS is a mandatory standard formulated by EU legislation. Its full name is the restriction of hazardous substances. It has been officially implemented since July 1, 2006. It is mainly used to standardize the material and process standards of electronic and electrical products, so as to make it more conducive to human health and environmental protection. The purpose is to limit the use of harmful substances in electronic and electrical products, so as to promote the environmental regeneration and final treatment of waste electronic and electrical equipment, so as to ensure human health. The directive specifies the limit requirements for toxic and harmful substances, and also requires countries to comply with 2002 / 95 View >>

After the IC chip packaging process is completed, it must undergo strict testing to ensure the quality of products. Chip appearance testing is an essential and important link, which directly affects the quality of IC products and the smooth progress of subsequent production links. However, in the process of manufacturing products, surface defects are usually inevitable. At present, automatic intelligent detection and identification has been used to replace manual judgment in the detection of many electronic products. While improving efficiency, it can reduce the labor cost of enterprises, keep the machine in a high-precision standard working state for a long time, and effectively avoid the adverse effects caused by manual fatigue, misjudgment and missed judgment.

Components are the basis of the whole machine. The inherent reliability of electronic components depends on the reliability design of products. In the manufacturing process, due to its inherent defects or improper control of manufacturing process, the final finished products cannot achieve the expected inherent reliability. How to accurately and effectively detect the relevant parameters of components and determine whether the components are normal or not, different methods must be adopted according to different components, so as to detect whether the components are normal or not. Therefore, before the electronic components are installed on the whole machine and equipment, we should try to eliminate the components with early failure as much as possible. Therefore, we should screen the components. Several common electronic components screening items are introduced below. View >>

The third-party testing organization, also known as fair test, refers to an object other than two interrelated subjects, which we call the third party. Common electronic components include signal amplifiers, receivers, capacitors, adapters, power lines, converters, data connecting lines, network cables, circuit boards, resistors, triodes, connectors, diodes, etc. core detection always adheres to the purpose of "professionalism, authority, efficiency and innovation" and spends a lot of money to purchase international advanced detection equipment, In strict accordance with international testing standards and methods, the test has obtained CNAs certification and international mutual recognition qualification. The customer base covers many countries and regions at home and abroad. It is a professional IC testing institution with excellent quality and high popularity in China. View >>

How to identify the authenticity of components? First of all, we need to understand the difference between original genuine goods and bulk new goods, so as to identify the authenticity of components. It should be noted that parallel goods and fake goods are not the same concept. Fake goods refer to counterfeiting and forging other people's brands and models. Parallel goods refer to goods that come in through tax evasion. In addition, there is a kind of new goods, that is, renovating the used old real goods and then selling them as new goods. These are all hidden quality risks. Chip detection teaches you to reject fake goods and identify genuine ones. Let's have a look. View >>

IC chip (integrated circuit) is an integrated circuit formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) IC chips on a plastic base to make a chip. Now almost all the chips we see can be called IC chips. Chips play an important role in our daily use of computers, mobile phones and other modern electronic equipment. We can imagine the importance of IC chip quality. However, in the face of very realistic shapes in the market, we can't distinguish IC chips with defective internal structure with the naked eye. The following is a complete collection of IC chip detection methods, hoping to help you. View >>
