Test EQ

BYD Vehicle Icing Low-Temperature Chamber Delivered at Auto China 2026At the 2026 Beijing International Automotive Exhibition (Auto China), TestEQ officially announced the successful delivery of a vehicle icing low-temperature environmental test chamber to BYD, which was also showcased during the exhibition as a key automotive reliability testing solution.This system is designed for full-vehicle validation under extreme cold climate conditions, enabling engineers to simulate low temperature, rapid cooling, and controllable icing formation in a controlled laboratory environment.

The Guangxi GuiDian Technology Service Center is a joint research and innovation platform established by the Nanning Municipal Government and Guilin University of Electronic Technology. It integrates product testing, scientific research, and technology commercialization. TestEQ has delivered a full range of environmental test chambers to support its reliability testing, including temperature humidity chambers, thermal shock systems, altitude simulation chambers, rapid temperature change chambers, and battery safety testing equipment.

Technical Innovation and Application Prospects of Rapid Rate Thermal Cycling ChamberThe Rapid Rate Thermal Cycling Chamber, as a core equipment in the field of environmental simulation testing, has seen a significant increase in demand in industries such as electronics, aerospace, and new energy. Its core technology lies in achieving high-precision temperature changes (ranging from 5°C/min to 25°C/min) and a wide temperature range (-70°C to +200°C), to meet the reliability verification requirements of products in extreme environments. The ESS stress screening chambers launched by TestEQ support a maximum temperature change rate of 30°C/min, which can simulate rapid transitions from extreme cold to high temperatures, effectively exposing material thermal fatigue defects. The equipment achieves efficient heat exchange through air cooling or liquid nitrogen refrigeration systems and is equipped with multiple safety protection mechanisms (such as compressor overpressure protection, phase sequence detection, etc.), ensuring the stability of the testing process.

Technology leads the future | TestEQ successfully made it into the list of technology-based small and medium-sized enterprises in Guangdong Province for 2025

TestEQ is a leading enterprise in the R&D and production of environmental simulation testing equipment. The company has been awarded the title of "Dongguan Intelligent Environmental Test Chamber Engineering Research Center," the only one of its kind in Dongguan to receive this honor.

What is a 22°C/min rapid temperature change chamber?A 22°C/min rapid temperature change chamber is a high-performance environmental test system designed to simulate extreme thermal stress by linearly changing temperature at 22 degrees Celsius per minute. It is widely used in semiconductor reliability testing to evaluate chip durability, thermal fatigue, and failure mechanisms under accelerated conditions.

Why Anti-Static Thermal Testing MattersIn high-reliability industries such as semiconductors, 5G communication, and automotive electronics, thermal cycling alone is no longer sufficient. Electrostatic discharge (ESD) has become a critical hidden risk that can cause latent defects and premature failures.Huawei’s equipment-level ESD requirements, for example, strictly limit static voltage exposure and require comprehensive grounding, humidity control, and anti-static protection systems to ensure device integrity .For manufacturers supplying to Huawei or similar Tier-1 OEMs, test equipment must not only simulate extreme temperature transitions but also eliminate electrostatic interference during testing.This is where TestEQ’s Anti-Static Rapid Thermal Cycling Chamber delivers a decisive advantage.

Amid the grandeur of China’s military parade showcasing national strength and technological prowess, TESTEQ (a leading Chinese provider of reliability testing solutions for military and aerospace applications) has been honored with multiple prestigious certifications, including the "AAA Corporate Credit Rating Certificate."
