    Temperature Cycle Test Specification Instructions In order to simulating the temperature conditions encountered by different electronic components in the actual use environment, Temperature Cycling changes the ambient temperature difference range and rapid rise and fall temperature change to provide a more stringent test environment. However, it must be noted that additional effects may be caused to material testing. For the relevant international standard test conditions of temperature cycle test, there are two ways to set the temperature change. First, Lab Companion provides an intuitive setting interface, which is convenient for users to set according to the specification. Second, you can choose the total Ramp time or set the rising and cooling rate with the temperature change rate per minute. List of International Specifications for Temperature Cycling Tests: Total Ramp time (min) : JESD22-A104, MIL-STD-8831, CR200315 Temperature variation per minute (℃/min) IEC60749, IPC-9701, Brllcore-GR-468, MIL-2164   Example: Lead-free Solder Joint Reliability Test Note: In terms of the reliability test of lead-free technetium-free points, different test conditions will be different for the temperature change setting, such as (JEDECJESD22-A104) will specify the temperature change time with the total time [10min], while other conditions will specify the temperature change rate with [10° C/min], such as from 100 °C to 0°C. With a temperature change of 10 degrees per minute, that is to say, the total temperature change time is 10 minutes. 100℃ [10min]←→0℃[10min], Ramp: 10℃/min,6500 cycle -40℃[5min]←→125℃[5min],Ramp: 10min, 200 cycle check once, 2000 cycle tensile test [JEDEC JESD22-A104] -40°C(15min)←→125°C(15min), Ramp:15min, 2000 cycle Example: LED Automotive lighting (High Power LED) The temperature cycle experimental conditions of LED car lights are -40 °C to 100 °C for 30 minutes, the total temperature change time is 5 minutes, if converted to temperature change rate, it is 28 degrees per minute (28 ° C /min). Test conditions: -40℃ (30min) ←→100℃ (30min), Ramp: 5min
