From July 1st to 3rd , 2026 , the highly anticipated electronica Shanghai will be grandly opened at the Shanghai New International Expo Centre.

Demosisto receives much attention

Guangdong Zhongzhi Testing Instruments Co., Ltd., located at booth 353 in Hall W5 , became one of the most eye-catching highlights of Hall W5 on the first day of the exhibition, thanks to its professional image in the field of environmental reliability testing in the semiconductor industry .

The booth of Zhongzhi Testing Instruments at the exhibition featured a simple yet elegant design, with its brand slogan "Energy Saving, Stable, and High-End" standing out prominently, attracting many domestic and international customers to stop and inquire.

Zhongzhi's high-end environmental testing equipment for the semiconductor industry is attracting attention, with a constant stream of customers, keeping the Zhongzhi reception team busy. They demonstrate equipment operation and explain core technical parameters to visitors while patiently answering their professional questions about high and low temperature testing of semiconductors, temperature and humidity reliability verification, and other related issues.

As a leading enterprise in domestic simulated environmental testing equipment, Guangdong Zhongzhi Testing Instruments was established in 2005. It is a national high-tech enterprise, a "specialized, refined and innovative" enterprise in Guangdong Province, and a reserve enterprise for listing in Dongguan City. It has more than 100 product patents , covering three core independent intellectual property rights systems: freezing, temperature control, and structure.

With 21 years of experience in the semiconductor industry, we are committed to providing customers with energy-saving, stable, and high-end environmental testing solutions.

In the field of semiconductor chip testing, Zhongzhi Testing Instruments has established a highly competitive technological barrier. Its semiconductor high and low temperature test chambers cover a temperature range of -80℃ to 150℃, wider than the industry standard of -70℃ to 150℃, meeting the full-scenario testing needs of semiconductor chips from low-temperature aging (LTOL) to high-temperature aging (HTOL). Temperature fluctuation is <±0.25℃, better than the industry standard of <0.5℃; through professional CFD simulation optimization of the airflow design, the load uniformity of the test area can reach 1℃ to 1.5℃, far exceeding the semiconductor industry's core requirement of ±0.5℃ to ±2℃ temperature uniformity.

For semiconductor high-temperature aging testing, ZTE provides professional high-temperature aging testing equipment ( precision high-temperature aging chamber, anaerobic high-temperature chamber, and cleanroom oven) covering four major scenarios: conventional high-temperature testing, high-temperature life testing (HTOL/HTSL ) , oxygen-free high-temperature processes, and cleanroom high -temperature processes . Linear temperature control is available across a wide temperature range of RT~300℃, with a 150℃ rise time of only 20 minutes, enabling efficient long-term high-temperature life testing of chips at 125℃~150℃.

Reliability testing during the mass production phase of semiconductor chips requires continuous operation over extended periods, and energy consumption and stability directly impact testing costs. Addressing this customer pain point, Zhongzhi Equipment employs second-generation advanced cooling and temperature control technology, achieving over 40% energy savings compared to traditional equipment . This significantly reduces long-term testing costs. Combined with an intelligent fault self-diagnosis system, it ensures 10,000 hours of trouble-free operation , providing more stable and robust support for chip reliability testing.
