Rapid Temperature Forcing for Semiconductor and Electronics Validation
The DERUI semiconductor temperature forcing system delivers a controlled hot or cold air stream directly to a device under test. It supports fast characterization of ICs, memory, PCBs, optical modules and 5G components while the DUT remains connected to electrical test equipment.
This Is a Temperature Forcing System—not a Heat Flux Meter
A heat flux meter measures heat-transfer rate per unit area. This equipment instead creates and controls a localized thermal environment around a DUT. The technically correct search terms are temperature forcing system, thermal stream or thermostream system.
IC Characterization
Measure functional and electrical behavior at hot, cold and intermediate case-temperature conditions.
Memory and Storage
Test Flash, eMMC and related devices for startup, timing and data performance across temperature.
5G and Optical Modules
Condition SFP/transceiver modules, RF devices and communication boards while connected to ATE or a functional test setup.
Focused Hot and Cold Air Around the DUT
Generate the Air Stream
Mechanical refrigeration and electric heating condition the process air over the selected operating range.

Integrating Thermal Stream with ATE
Characterize the Setup
Verify sensor placement, shroud sealing and the relationship between air, case and any estimated junction temperature.
Run the Sequence
Command the target, wait for the agreed stabilization rule, execute the electrical test and record temperatures with results.
Return Safely
Warm the DUT above the condensation-risk point before opening the shroud or removing it from dry-air protection.
Semiconductor Temperature Forcing System FAQs
What is a semiconductor temperature forcing system?
It delivers controlled hot or cold air to a localized DUT so electrical behavior can be measured at selected temperatures without conditioning a full chamber.
Is it a heat flux meter?
No. It does not primarily measure heat flux in W/m². It is a thermal-stream source and temperature-control system.
Does the DUT reach −55°C to +125°C in 13 seconds?
Not necessarily. The figure describes the stated air transition. DUT stabilization depends on thermal mass, power, fixture, airflow, sensor and tolerance.
Why use it instead of a temperature chamber?
It provides faster localized conditioning and easier access to probes, sockets and ATE, making it useful for device characterization and failure analysis.
Can it control junction temperature?
Directly controlling junction temperature requires a suitable electrical sensing or thermal model. Standard setups more commonly control air or package-case temperature.
Does it require liquid nitrogen?
The supplied specification states mechanical refrigeration without LN₂. The system still contains a closed refrigeration circuit; refrigerant type and service details should be confirmed.
How is condensation prevented?
Use dry conditioned air, a well-sealed shroud, controlled purge and warm-up, and keep the DUT protected until it is above the ambient dew point.
What should I send for selection?
Provide DUT/fixture drawings, power dissipation, target temperature, sensor/control point, transition and stability requirements, test sequence and laboratory utilities.
Configure the Thermal Stream Around Your DUT
Send DERUI your device, socket and fixture drawings, power dissipation, temperature profile, feedback method and ATE sequence. We will review the nozzle/shroud, airflow and control configuration.
