How the Thermal Shock Test Chamber effect on LED Products?
  • Theory: 

    Thermal Shock Testing Machine is used to test electrical and electronic components, automation components, communication components, auto parts, metal, chemical materials, plastic and other industries, the defense industry, aerospace, industrial, BGA, PCB base, electronic chip IC, semiconductor ceramics and polymer materials of physical change. Test the material reaction under  repeat tensile strength of the product’s chemical or physical harm under high and low temperature in heat bilges cold shrink condition, it used to confirm the quality of products, from precision IC to heavy mechanical components, there is no doubt regard it as a ideal testing tools.

    1.  The equipment is divided into high temperature box, low temperature box, test box of three parts, Adopt unique heat broken structure and heat storage effect, When execute testing, the object should in completely static condition, using the cold and hot wind path switching mode lead in the hot and cold temperature air hot to realized thermal and cold temperature shock test.

    2. Using the advanced measuring device, the compressor use a large color LCD controller with human-machine touch dialog type LCD human-machine interface controller, simple operation, stable and reliable; Chinese or English display the complete system operation conditions, implement and setting process curve. With 96 test specification to independent setting, impact time 999 hours 59 minutes, cycle 1 ~ 999 times can be set, which can realize automatic operation in the largest degree, reduce workload of the operating personnel, can run automatically start and stop work at any time.

    3. A diameter of 50 mm hole on the left side of the chamber for external power supply load wiring test components. Can seperately set high temperature, low temperature and the function of temperature cold and hot shock test. And can choose two-zone or three-zone, cold shock impact or thermal shock function when complement the cold and hot shock testing; and also it can be use as a High Low Temperature Humidity Test Chamber.

    4. It equip with  fully automatic, high precision system circuit, any parts action, Completely P.L.C lock handle and the P.I.D automatic calculus  control, high precision temperature control. Advanced science and air circulation loop design, make indoor temperature uniformity, avoid any blind corner; completely protective devices to avoid any predictable safety problem to ensure the lifetime of the machine.

    5. Cycle and defrost times can be set automatically or manual. The air outlet is controlled by the sensor, Ventilation door  switching time will be finished in 10 seconds. And the DGBELL brand Thermal Shock Test Chamber only use 5 minutes to recovery the temperature. Display curve in the operation, when abnormal status occurs, it will screen display the failure point and the reasons and provide troubleshooting methods; it also with a function of emergency stopping device when the power supply is unstable.

    6. Refrigeration system use the covering type high efficient low temperature circuit system, the compressor adopt Europe and the United States imported compressor unit, and use green environmental protection refrigerants(HFC) R507, R23 which ozone coefficient is zero. Strong safety protection function: power overload protection overload, short circuit protection, leakage protection, control circuit, compressor protection, grounding protection, over temperature protection, warning voice prompt, and so on.
