Temperature Test Chamber

SHARE

Sonacme Temperature Test Chambers can set different stress screening temperature change rates: 5?/Min, 10?/Min, 15?/Min, 20?/Min, 25?/Min. Temperature cycling stress screening is the use of temperature acceleration techniques (cycle within the upper and lower limit temperature, the product produces alternating expansion and contraction) under the design strength limit of the product to change the external environmental stress. Meet the stress screening of electronic equipment products, MIL-STD-2164, MIL-344A-4-14, MIL-2164A-19, NABMAT-9492, GJB-1032-90, GJB/Z34-516, IPC-9701... etc. Test requirements.

The stress screening test of the temperature test chamber from room temperature is based on MIL-STD-2164 and IEC 60068-2-14. When performing the temperature cycle stress screening test, it needs to start from room temperature, which is the same as the traditional thermal shock test. The experiment is different.

Uniform temperature, isothermal mode
  • According to the change of the slope of the temperature cycle required by the specification, the temperature slope mode of average temperature [ESS] and linear isothermal [RAM P] can be executed.
  • The inner chamber material is made of SUS#304 stainless steel with 1.2mm thickness. Full welding structure, its sealing is very well and it’s not easy to get cracked.
  • The external material is made of cold-rolled plate with 1.5mm thickness, it has gone through brushing, polishing, painting treatment, it`s not easy to get scratched.
  • The insulation material is made of polyurethane foam with thicknessof 100mm.
  • The door seal adopts double silicon rubber sealing material.
  • The observation window is 4 layers of tempered glass, the size you can choose by yourself.
  • In addition, in order to prevent frosting on the observation window when running low temperature, we setup a heating wires inside to get it di-frosting.
  • Compressors equipped with world famous brand such as Tecumseh (France made), Bitzer or GEA BOCK (Germany made).
  • Shock absorption and noise reduction process,slow down the vibration, protect the compressor.
  • The new pipe bending technology: The bending process can minimize the connector point and make refrigerant flow more efficiently.
  • It applies Denmark DANFOSS and Japanese SAGLNOMIYA solenoid valves to improve the overall reliability of the equipment.
  • MP10 module has motor over-heating protection (with LED indicator), exhaust temperature over-heating protection (requires optional temperature monitoring probe and LED indicator), power indicator, alarm function.
