【团体标准】 半导体温差发电(TEG)器件测试方法

本标准针对半导体温差发电器件可靠性测试，涵盖机械应力、气候环境和使用寿命试验。机械应力试验包含机械冲击、振动、抗剪切等，考核器件结构强度；气候环境试验有高温、温度冲击等，评估环境适应能力；使用寿命试验基于阿伦尼乌斯方程推算器件寿命。每项试验均明确原理、设备、步骤及结果计算评估方式，适用于该类器件可靠性测试，确保其在多种条件下性能稳定。Thisstandardfocusesonthereliabilitytestingofsemiconductorthermoelectricgenerator(TEG)devices,coveringmechanicalstresstests,climaticenvironmenttests,andservicelifetests.Mechanicalstresstestsincludemechanicalshock,vibration,andshearresistancetoassessthedevice'sstructuralstrength.Climaticenvironmenttestsinvolvehightemperature,thermalshock,etc.,toevaluateenvironmentaladaptability.Theservicelifetestestimatesthedevice'slifespanbasedontheArrheniusequation.Eachtestspecifiestheprinciple,equipment,procedures,andresultcalculation/evaluationmethods,suitableforreliabilitytestingofsuchdevicestoensurestableperformanceundervariousconditions.
