IEC61215 UL1703 Thermal cycling Humidity-freeze testing equipment testing machine environment chamber

Testing standard 

It's according to IEC61215-2:2016 testing standard 

Purpose

To determine the ability of the module to withstand the effects of long -term penetration of humidity, & the ability of the module to withstand thermal mismatch , fatigue and others stresses caused by repeated changes of temperature

Testing Chamber advantage

Have three function:

1. Damp heat testing ( double 85℃ testing)

2. Thermal cycling testing

3. Humidity freeze testing

Testing chamber structure introduce

The Mainly specifications

1. Temperature range: -40 to 100℃, and the temperature fluctuation ≤±1℃,

 the deviation ≤±1℃ and the uniformity:≤±1℃

2. Humidity range:30 to 98%RH, the relative humidity deviation:±3%FS, deviation 85±2%RH,  

90±2%RH, Humidity fluctuation :±2%RH, humidity uniformity:≤2%RH

3. The electricity:380V 60HZ

4. Damp heat testing: common moisture point: 85℃/85%RH ,the sustainable time ≥1000H,90℃/95%RH,the sustainable time ≥1000H

5. Humidity freeze temperature go up & go down speed rate:

A.from 25℃ to 85℃ , the speed is 100℃/h(1.6℃/Minute),

B.from 85℃ to 0℃,the speed is 100℃/h (1.6℃/Minute),

C.from 0℃ to -40℃, the speed is 200℃/h (3.3℃/Minute),

D.from -40℃~0℃, the speed is 200℃/h (3.3℃/Minute)

E.from 0℃ to 85℃, the speed is 100℃/h (1.6℃/Minute)

F.Testing cycle times:50

6.Thermal cycle testing: the temperature change rate of module surface should not more than 100℃/h(1.6℃/Minute),testing cycle times: 200
