Recently, Guangdong Haotian Testing Instrument Co., Ltd. independently developed customized productsRapid temperature change test chamberFormally delivered to a leading domestic chip manufacturing enterprise, the equipment will be directly put into the mass production testing of automotive grade and industrial grade chips, providing core guarantees for chip reliability. This marks the recognition of Guanghaotan's customization capabilities in the field of semiconductor testing equipment.
With the development of chips towards high integration and wide temperature range, the impact of temperature environment on performance is becoming increasingly significant. The test chamber delivered this time has achieved multiple technological upgrades to meet the needs of the enterprise. It is equipped with a two-stage compression refrigeration system and an efficient heating module, with a temperature change rate of 20 ℃/min and a temperature control accuracy of ± 0.3 ℃. It can accurately simulate temperature change scenarios from -55 ℃ to 150 ℃ and reproduce the temperature fluctuation conditions of the chip during car start stop and industrial environment switching.
The absence of condensate interference is the core highlight of this device. It adopts a two-stage system of "pre dehumidification+dynamic humidity control" to control humidity fluctuations within ± 1.5% RH, avoiding the erosion of chip precision circuits by condensed water from the source and solving the testing pain points of traditional equipment. The device also supports 300 sets of program presets, which can adapt to the full process testing from R&D verification to mass production sampling, increasing the early failure rejection rate of chips by more than 30%.


The device has undergone three months of rigorous testing, and its data repeatability and long-term stability meet our standards. The testing manager of the chip company stated that the test chamber can efficiently expose chip packaging defects, solder joint virtual connections, and other issues, providing key support for the product to comply with industry standards such as AEC-Q100.
