Zhongzhi Automotive-Grade Rapid Temperature Change Test Chamber (CZ-USA Series) is a high-end testing equipment specially developed for environmental reliability testing of automotive-grade chips, automotive electronics, and new energy devices. Its core positioning is dedicated equipment for AEC-Q100-certified temperature cycling tests and Environmental Stress Screening (ESS). The standard temperature range is -70°C~+150°C, fully covering the complete temperature range required for AEC-Q100 Grade 0 (-40°C~150°C) and Grade 1 (-40°C~125°C) certification. The standard configuration is a 15°C/min linear temperature change rate, meeting the mandatory requirements of JEDEC JESD22-A104 and AEC-Q100 for semiconductor temperature cycling transition rates right out of the box, without requiring additional customized upgrades. It also provides multiple levels of linear and nonlinear programmable modes at 5/10/15/20°C/min, while customized models can achieve an ultra-high-speed temperature change rate of 25°C/min, allowing one piece of equipment to cover full-scenario requirements from basic screening of consumer electronics to automotive-grade certification. The equipment is widely used in AEC-Q100 temperature cycling certification of automotive-grade chips, high- and low-temperature durability verification of automotive controllers (ECU/domain controllers), reliability evaluation of power battery packs, and environmental stress screening of electric drive and electronic control systems. It is fully compatible with core domestic and international standards such as JEDEC JESD22-A104, AEC-Q100, GB/T 28046, ISO 16750-4, VW 80000, SAE J2380, and ECE R100.
