Entering 2026, the semiconductor industry is undergoing a paradigm shift from “functional verification” to “full life cycle reliability evaluation.” As chip processes evolve toward more advanced nodes, the reliability testing requirements for automotive-grade chips and AI accelerator chips continue to increase. According to QYResearch data, the global sales of the chip temperature cycling testing market reached RMB 5.236 billion in 2025. Meanwhile, in the first quarter of 2026, the localization rate of semiconductor equipment in China reached 27%, an increase of 12 percentage points year-on-year. Under the dual pressure of surging testing demand and cost control, chip companies need environmental test equipment with professional performance and high cost-effectiveness more than ever.

Deeply Engaged in the Industry for More Than 20 Years, Zhongzhi Builds Professional Expertise in Chip Environmental Testing

Guangdong Zhongzhi Testing Instruments was established in 2005 and is a National High-Tech Enterprise integrating the R&D, production, sales, and service of environmental simulation and reliability testing equipment. It is also a Guangdong “Specialized, Specialized and New” Enterprise and a Dongguan listed-company reserve enterprise. The company has more than 300 employees and annual sales exceeding RMB 300 million, with branches and service outlets established in key cities across the country. With more than 100 product patents and support from 30,000+ customer cases, Zhongzhi has become a professional force in the field of chip environmental reliability testing equipment.

Against the background of extremely stringent temperature control accuracy requirements for semiconductor chip testing, Zhongzhi Testing Instruments has achieved an industry breakthrough in temperature control technology—the equipment covers a temperature range of -70°C to 150°C, with temperature fluctuation of <±0.25°C, better than the industry standard of <0.5°C; through professional CFD simulation and optimized air duct design, the temperature uniformity under load in the test area reaches 1°C to 1.5°C. Relying on its independently developed new control system, the equipment achieves a temperature measurement accuracy of 0.01°C. These indicators provide reliable assurance for the accuracy and consistency of chip test data.

From Benchtop to Walk-In, Zhongzhi Builds a Full-Scenario Chip Testing Product Matrix

In response to the diverse testing needs of the chip industry, Zhongzhi has built a full-range product system. The 20L Benchtop Temperature Chamber is one of the highlights—it can be placed directly on a desk, operates with a 220V power supply, and consumes only 1 kWh of electricity per hour, greatly reducing testing costs. Its temperature range covers -70°C to +150°C, with core performance indicators fully consistent with those of large equipment. For chip companies with special requirements, Zhongzhi can also provide full-size non-standard customization services ranging from HAST High Pressure Accelerated Aging Test Chambers to large walk-in environmental chambers of 4–1200m³ and above.

For semiconductor high-temperature aging testing, Zhongzhi has launched the 27L Benchtop Temperature Chamber CZ-UT-27T, with a temperature range of RT to 200°C and a heating rate of ≥5°C/min, suitable for high-temperature aging testing of high-precision, small semiconductor devices. Its standard precision high-temperature aging test chamber CZ-UT Series supports wide-range linear temperature control from RT to 500°C, with heating to 150°C in only 20 minutes, enabling efficient completion of long-term high-temperature life testing of chips at 125°C to 150°C. The products cover the full range of semiconductor chip testing needs, including Temperature Test Chamber, Temperature and Humidity Test Chamber, Rapid Temperature Change Test Chamber, Thermal Shock Test Chamber, and more.

Combining High Performance and Low Cost: Zhongzhi Redefines “Cost-Effectiveness” in Chip Testing

Market data in 2026 shows that domestic equipment, with its high precision, high cost-effectiveness, and strong customization capabilities, has become an important choice for semiconductor companies to replace imported equipment. Zhongzhi Testing Instruments is a typical representative of this trend.

In terms of performance, the temperature fluctuation, uniformity, and other core indicators of Zhongzhi equipment are better than industry standards; the equipment is equipped with a new-generation independently developed intelligent control system that can monitor and record more than 200 key variables in real time; the products meet domestic and international testing standards such as GB, GJB, IEC, and MIL-STD.

In terms of cost, the low-energy-consumption design of benchtop equipment, which consumes only 1 kWh of electricity per hour, the price advantages brought by the domestic supply chain, and the localized rapid-response service model together form Zhongzhi’s high cost-effective solution of “high performance + low cost.” In 2026, the procurement logic for chip testing equipment has upgraded from “meeting standards” to “exceeding standards”—Zhongzhi uses professional technical strength and practical cost control to help chip companies effectively control budgets without sacrificing testing quality.

Conclusion

In 2026, domestic substitution of semiconductor testing equipment is entering a strategic window. Based on more than 20 years of technical expertise, Guangdong Zhongzhi Testing Instruments provides the chip industry with an environmental reliability testing path that balances quality and cost through a professional product matrix and practical high cost-effectiveness strategy. From benchtop to walk-in, from standard equipment to non-standard customization, Zhongzhi is using “professionalism + high cost-effectiveness” solutions to support the high-quality and reliable development of China’s chip industry.
