Chips are booming, and domestic substitution is developing rapidly
Hygon Information’s market value exceeds 500 billion yuan
Cambricon’s market value exceeds 600 billion yuan
SMIC’s market value exceeds 1 trillion yuan
….
In September, the chip sector in the A-share market surged, once again becoming the focus of the market. Against the backdrop of the United States continuously increasing restrictions on high-end chip exports to China, the urgency for China’s chip industry to achieve independent and controllable autonomy is becoming increasingly prominent. Especially in the field of analog chips, with the Ministry of Commerce launching anti-dumping investigations into analog chips originating from the United States, the trend of domestic substitution has further strengthened, bringing new development opportunities to domestic chip companies.
Chip manufacturing. Environmental reliability testing is crucial
There are various types of chips; here, they are divided into seven categories based on function. In chip manufacturing, packaging, and testing, environmental reliability testing is an indispensable part of ensuring the quality of finished chip products. It includes tests for high and low temperatures, humid heat, temperature shocks, vibration, and other comprehensive tests, directly affecting the chip’s operating condition and lifespan in extreme environments.
With the explosive growth in AI computing power demand, chip power consumption and heat generation have increased significantly (some GPUs/TPUs consume over 200W), placing stricter requirements on test temperature range, temperature variation rate, and precision control. With years of technical expertise and industry experience, SCICOOLING has become a reliable partner in this field. In previous articles, we introduced the wide applications of SCICOOLING test chambers in the semiconductor industry; this article is dedicated to their use in the “finished chip” sector.
A reliable partner for chip environment testing
SCICOOLING originates from the Institute of Physics and Chemistry, Chinese Academy of Sciences, and has focused on the research, development, and manufacturing of environmental test equipment for 20+ years. The company’s products cover high and low temperature (damp heat) test chambers, temperature shock chambers, rotary table vibration isolation temperature chambers, altitude test chambers, combined environmental test chambers, walk-in test chambers, ultra-low temperature equipment, and more. Its equipment is renowned for its high precision, long lifespan, energy saving, and non-standard customization.
To date, SCICOOLING has provided testing solutions to nearly a hundred leading chip industry companies and listed companies. Representative clients include CETC, China Electronics, China Aerospace, China Aerospace Science and Industry Corporation, Institute of Microelectronics, Chinese Academy of Sciences, Zhongke Haiguang (China’s leading high-end CPU R&D company), GoerTek, GigaDevice (a global leader in fabless chip suppliers), Guangxun Technology (domestic leader in optical communication chips), Jingjia Micro (a leading domestic GPU chip company), AAC Technologies (ranked among the top three globally in MEMS microphone chip shipments), Innosilicon (internationally advanced MEMS inertial chips), Shanghai Belling (leader in domestic analog chips), and Huali Chuangtong (a listed company in Huawei mobile phones and satellite communication baseband chips), covering various mainstream domestic chip fields. Most test chambers require high precision, have strong non-standard attributes, and many details are tailored to customer requirements.
