Compared with the traditional rapidly temperature shock chamber, thermal shock chambers, The main advantages of the temperature forcing system include:

• The rate of temperature change is faster; temperature forcing system Precision of temperature control: ±1 ℃
• Real-time monitoring of real temp of the components to be tested, the impact air temperature can be adjusted at any time.
• For a single IC(module) of many components on the PCB circuit board, high and low temperature shock can be carried out independently without affecting other peripheral devices.
• Temperature forcing system treat with the test beach of load board, For IC lead frame temperature shock test.

Control System

• The thermal control system keeps advanced and reasonable structure design, Manufacturing process conforms to the specification, with beautiful appearance.
• The main functional components of the thermal control system is equipped with the world famous brand configuration. The noise and energy saving to get the best control of its performance can replace similar foreign products, like in TEST Thermal Solutions, Thermostream -80°C to +225°C.
• The matching and assembly of parts and components are good, the main functional components are used with the international advanced level of the original imported parts, improve the safety and reliability of the thermal control system, to ensure the service life for users and high frequency requirements.
• Thermal control system has good operation and excellent temperature stability and durability, good safety performance, and does not pollute the environment and endanger human health.
• Qualitest has the mechanical vibration shaker and environmental test equipment for high temperature, low temperature and humidity vibration inspection and control for our temperature forcing system.
• In the production process, each process shall be self-checked and cross-checked before passing the inspection by the quality department before flowing into the next process.
• When the Thermal Control System leave our site, intelligent temperature and humidity inspection instrument is equipped with a special high-precision test platinum resistance for strict ex-factory inspection as well.

Working Principle

• The output airflow cover of the thermal control system will be covered by the test product. This way will form a test room in a closed space
• The high or low temperature airflow output by the thermal control system makes the surface temperature of the tested product change dramatically.
• Thus, the corresponding high and low temperature impact test is completed.
• Thermal control system can be used for a number of components in a single IC plate or the overall IC template components.
• Isolate it for high and low temp impact, and it does not affect the other peripheral devices.
• Compared with traditional shock chamber, the impact rate of temperature variation is faster.
• Make your test with high temp to room temp to low temp ｜high temp to low temp｜high temp to room temp｜low temp to room temp and adaptive program as well.

Advanced Energy Saving Design

• Thermal stream instrument includes PID + PWM principle, VRF technology (electronic expansion valve is controlled by refrigerant flow servo based on thermal energy condition)
• Low temperature operating state, heater does not participate in the work, Adjust refrigerant flow and flow direction by PID + PWM
• Adjust the flow rate of refrigeration pipeline, cold bypass pipeline and hot bypass pipeline, Achieve automatic constant of the studio temperature.
• This method can reduce energy consumption by 30% at low temperature.

Compressor Temperature Adjustment

• Automatically adjust the return temperature of the thermal stream equipment test system compressor
• Temperature Forcing System keep the compressor temperature in the normal range, Avoid compressor cooling and overheating

Refrigeratory Technology

• In the design of refrigeration system, the protection measures of compressor are taken into full consideration. Such as compressor suction & exhaust pressure automatic protection function.
• This keeps the operating temperature of the compressor within the normal temperature range, avoid compressor cold or overheating In order to extend the service life of the compressor.
• In the refrigeration system pipeline welding adopts the high – quality oxygen – free copper tube gas – protected welding.
• This method avoids the damage to the refrigeration system and compressor caused by oxide produced in the inner wall of copper pipe by the traditional welding method.
• In the design of thermal testing equipment refrigeration system, the vibration reduction measures during unit operation are fully considered.
• If the compressor installed spring shock absorber, At the same time, the cooling pipe is added with arc bending, Avoid pipe deformation and leakage caused by running vibration and temperature change, So as to improve the reliability of the whole thermostream instrument refrigeration system.

Energy Conservation Measure

• Following effective energy regulation measures were adopted: Such as: refrigeration system cooling capacity regulation, gas-liquid bypass regulation, evaporation temperature regulation.
• When the temperature is constant at any low temperature point, no heating equilibrium is required. Operating power can be reduced to half. The operating cost and failure rate of the refrigeration system are reduced to a more economical state.

Measure of Vibration Mitigation

• The temp test solution refrigeration system piping shall be added with R and elbow to avoid the copper pipe deformation caused by the change of vibration and temperature. This causes the refrigeration system pipeline to break.
