Is there a good component or chip testing institution in China?

With the increasing demand for miniaturization of electronic devices, the functions of a single chip are increasing. In the prior art, in order to ensure the quality of the chip, the chip testing stage is usually included between the design molding and mass production. However, the traditional chip debugging technology is an additional set of function-specific test procedures developed based on the chip function, which can usually only detect whether the chip has errors or faults, and cannot accurately locate the errors in the chip terminal, and can only be judged by the experience of the inspectors, resulting in slow chip detection speed and low efficiency.

Chip is a general term for semiconductor component products, also known as microcircuits, microchips, and integrated circuits. Refers to a silicon wafer containing an integrated circuit, which is small in size and is often part of a computer or other electronic device. All of these components have been structurally integrated into a single unit, making electronic components a big step towards miniaturization, low power consumption and high reliability.

It is denoted by the letters "IC" in the circuit. The inventors of integrated circuits are Jack Kilby (silicon-based integrated circuits) and Robert Noyce (germanium-based integrated circuits). Most applications in today's semiconductor industry are silicon-based integrated circuits.

China Electronic Component Center Laboratory, referred to as CECC Laboratory (CECCLAB), is a global third-party component testing institution, a national key training laboratory, a member of China Semiconductor Industry Association, and a member of the China branch of the international IECQ-CECC quality standard system. The CECC laboratory test and analysis standards are based on international JEDEC standards, MIL-STD-883 standards, and IPC standards, and the authority of its test reports has been recognized by the European Union, the United States and Japan.

The CECC laboratory integrates the hardware resources of the National Integrated Circuit Base, the Hong Kong University of Science and Technology, the Chinese Academy of Sciences, Peking University and the South China University of Technology to create the most comprehensive and high-end IC testing and verification platform in China.

In addition, universities such as Beihang University and the Military Commission also have similar testing institutions, such as electronic component testing centers.

Chip third-party testing company rankings: Teradyne, NASDAQ: TER, Advantest, Cohu, Changchuan Technology, Huafeng Measurement and Control, Zhimao Electronics, Jiuyuan Shili Electronics.

Third-party chip testing companies can customize testing services according to customer needs to meet customers' strict requirements for chip function, performance and quality. During the testing process, customers are also able to adjust the chip design ideas in a timely manner based on feedback from independent testing companies to avoid waste caused by large-scale tape-out.

Compared with traditional integrated packaging and testing manufacturers, third-party testing manufacturers have three advantages.

Third-party test manufacturers do not participate in other processes of chip manufacturing, so there is no tilt in position, and all potential problems in chip design, tape-out, and packaging can give objective and fair suggestions to help the development of Chinese chip enterprises in a more professional way.

Chip testing has shown a gradual trend of high-end, with high technical content and knowledge-intensive characteristics, and it is difficult for traditional packaging and testing companies or industries to have enough funds and energy to cope with the replacement of the industry. The granularity of independent third-party testing companies is more detailed, which can focus on the forefront of the industry and further promote the development of China's chip industry.

The role of the chip:

A chip is a highly integrated circuit board, which can also be called an IC, for example, the CPU of a computer is actually a chip, and different ICs have different functions.

If the ** processor CPU is compared to the heart of the entire computer system, then the chipset on the motherboard is the torso of the whole body, for the motherboard, the chipset almost determines the function of the motherboard, and then affects the performance of the entire computer system, the chipset is the soul of the motherboard. <>

In fact, electronic component companies are generally more professional, like our Shanghai Ruishu Electronics is to let professional people do it, please ask the landlord to ask this is to do Shenma!

Electronic components testing, you are asking is quite professional, although I work in Shanghai Ruishu Electronics, but also a member of a large electronic components company, but very professional testing I only know one or two! Look at their professional electronic component testing is also very professional, according to different power, different models of testing! It's a little complicated!

First, see if the label is correct, and then use professional technology to detect!

The inspection of electronic components is very complicated! It's not a simple sentence that can explain the method of electronic component testing! The detection of electronic components should be located according to the attributes of the electronic components you provide, and "prescribing the right medicine" is the key!

Step 1 of electronic component testing: understand the properties of electronic components!

The second step of electronic component detection is to select the corresponding method according to the properties of the electronic component!

The third step of electronic component testing is: the implementation of this electronic component testing method!

See what component you're inspecting.
