inTEST Temptronic ThermoStream ATS-535 Integrated Compressor Thermal Shock System

Overview

The inTEST Temptronic ThermoStream ATS-535 is a high-performance, integrated-compressor thermal shock system engineered for rapid, precise, and repeatable temperature cycling of electronic components—particularly semiconductor devices, power management ICs, RF modules, and aerospace-grade microelectronics. Unlike conventional thermal shock chambers requiring external compressed air infrastructure, the ATS-535 embeds a dedicated oil-free scroll compressor within its chassis, enabling full operational autonomy without auxiliary air supply lines, nitrogen dewars, or CO₂ tanks. Its core methodology relies on forced convection using conditioned, dry air streams directed through a focused thermal shroud (heat flow hood) that envelops the device under test (DUT). This architecture delivers true DUT-centric thermal control—not chamber ambient control—by directly regulating surface temperature via closed-loop feedback from T- or K-type thermocouples mounted in direct contact with the DUT. The system achieves thermal transitions across extreme ranges (−60°C to +225°C) with sub-second response latency, making it suitable for qualification testing per JEDEC JESD22-A104 (Thermal Shock), MIL-STD-883 Method 1010, and AEC-Q200 stress protocols.

Key Features

• Integrated oil-free scroll compressor: Eliminates dependency on external compressed air systems, reducing facility integration time, noise footprint (<70 dBA), and total cost of ownership.
• DUT-focused temperature control: Proprietary real-time algorithm adjusts airflow temperature and velocity based on live thermocouple feedback—ensuring thermal accuracy at the component level, not just at the shroud inlet.
• Ultra-fast thermal transition: Achieves −40°C → +125°C in under 12 seconds and +125°C → −40°C in under 40 seconds—enabling high-throughput screening and accelerated life testing.
• Zero-cryogen operation: No liquid nitrogen or CO₂ required; uses environmentally compliant, non-ozone-depleting refrigerant (R-513A or equivalent).
• Dual-mode operation: Supports both Air Mode (open-loop shroud temperature setpoint) and DUT Mode (closed-loop surface temperature regulation) for flexibility across R&D and production environments.
• Comprehensive safety architecture: Over-temperature cutoff (factory-set at +225°C, user-adjustable), refrigeration standby mode during heating-only phases, and automatic fault logging.
• Regulatory-ready design: CE-marked, RoHS-compliant, and compatible with FDA 21 CFR Part 11–aligned data integrity workflows when paired with validated LabVIEW™ drivers.

Sample Compatibility & Compliance

The ATS-535 accommodates a broad spectrum of electronic packages—from bare die and wafer-level chips to QFN, BGA, SOIC, and multi-chip modules—via customizable thermal shrouds and fixture interfaces. Its compact, benchtop-integrated form factor (194.7 × 61.7 × 108.6 cm) allows deployment in Class 10,000 cleanrooms, office-based R&D labs, and automated test cell environments where space and acoustic constraints prohibit traditional air-supply-dependent systems. The unit meets ISO/IEC 17025 calibration traceability requirements through NIST-traceable thermocouple verification and supports GLP/GMP audit readiness via timestamped, operator-logged thermal profiles stored internally or exported via IEEE-488 (GPIB) or RS-232. It complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and its CFC-free refrigerant satisfies EU F-Gas Regulation (No. 517/2014) and EPA SNAP program criteria.

Software & Data Management

Control and monitoring are executed via an intuitive rotary-knob interface with LCD display, supporting manual operation without host PC dependency. For automated integration, the ATS-535 provides native LabVIEW™ drivers, SCPI command sets over RS-232 and IEEE-488, and optional Ethernet-enabled remote control modules. All thermal profiles—including ramp rates, dwell times, setpoints, and real-time DUT temperature traces—are timestamped, stored in non-volatile memory (up to 1000 cycles), and exportable as CSV or XML. Audit trails include operator ID (via optional login module), parameter change history, alarm events, and calibration status—facilitating compliance with ISO 9001, IATF 16949, and FDA 21 CFR Part 11 requirements when deployed in regulated manufacturing environments.

Applications

• Qualification and reliability screening of power management ICs (PMICs), DC-DC converters, and voltage regulators used in satellite communications, GNSS receivers, and avionics systems.
• Thermal shock validation of automotive electronics per AEC-Q100 Grade 0/1 and AEC-Q200 standards.
• Failure analysis (FA) support: Correlating parametric drift (e.g., leakage current, switching delay) with transient thermal stress exposure.
• Design verification testing (DVT) of MEMS sensors, RF front-end modules, and high-speed SerDes transceivers under dynamic thermal load conditions.
• Production burn-in acceleration where traditional oven/chiller stacks cannot meet cycle time or spatial constraints.

FAQ

Does the ATS-535 require external compressed air?
No. The system integrates a sealed, maintenance-free scroll compressor and delivers consistent 5 SCFM airflow without external air lines or pressure regulators.
What thermocouple types are supported for DUT temperature feedback?
T-type and K-type thermocouples are natively supported; cold-junction compensation is performed internally with ±0.1°C resolution.
Can the ATS-535 operate continuously for extended qualification tests?
Yes. Designed for 24/7 operation in production environments, it features redundant thermal fusing, refrigerant pressure monitoring, and predictive compressor health diagnostics.
Is NIST-traceable calibration documentation provided with the instrument?
Each unit ships with a factory calibration certificate referencing NIST-traceable standards; annual recalibration services are available through inTEST-certified service centers globally.
How is condensation prevented during low-temperature testing?
The thermal shroud maintains positive air pressure and incorporates desiccated airflow conditioning to suppress dew point formation—eliminating moisture-related failure modes during −60°C exposure.
