inTEST ThermoStream ATS Series High-Speed Thermal Shock Test Chamber

Overview

The inTEST ThermoStream® ATS Series represents the current generation of high-speed thermal shock and rapid temperature cycling test systems, engineered for precision, repeatability, and compliance with international reliability testing standards. Building upon the legacy of Temptronic (founded 1970, acquired by inTEST in 2000) and Thermonics (founded 1976, acquired in 2012), the ATS platform integrates decades of empirical thermal control expertise with modern fluid-dynamic architecture and closed-loop PID regulation. These systems operate on forced-convection air-based thermal transfer—eliminating liquid coolant handling risks while enabling ultra-fast transient response. Core applications include JEDEC JESD22-A104 (Temperature Cycling), JESD22-A106 (Thermal Shock), MIL-STD-883 Method 1010 (Temperature Cycling), and IEC 60068-2-14 (Change of Temperature). The ATS Series delivers controlled, repeatable thermal profiles across wide operational envelopes—from cryogenic -100 °C to high-temperature +300 °C—with ramp rates exceeding 100 °C/min under defined load conditions.

Key Features

• Modular thermal delivery architecture with integrated or external compressed air supply options (ATS-535 includes built-in compressor)
• High-fidelity temperature control via dual-sensor feedback (chamber inlet + DUT proximity), supporting ±0.5 °C accuracy over full range
• Scalable airflow capacity: 4–18 standard cubic feet per minute (scfm), optimized for both small IC packages and large PCB assemblies
• Unified user interface across all ATS-500 and ATS-700 models—enabling consistent programming, logging, and alarm management
• Robust mechanical design compliant with ISO 14001 environmental manufacturing practices and RoHS directives
• Support for extended-duration stress testing (e.g., 24/7 operation at MIL-STD-883 Level H conditions)

Sample Compatibility & Compliance

The ATS Series accommodates a broad spectrum of test specimens—from bare die and QFN/QFP packages to populated circuit boards and hybrid modules up to 300 mm × 300 mm. Each system supports direct-on-DUT nozzle configurations as well as integration into custom environmental chambers or thermal vacuum enclosures. All models meet essential electromagnetic compatibility (EMC) requirements per EN 61326-1 and safety standards per UL 61010-1. Calibration traceability follows NIST guidelines, and system validation protocols align with ASTM E2293 (Standard Practice for Thermal Cycle Testing of Electronic Components) and IPC-9701A (Performance Requirements for Lead-Free Solder Attachments). Full audit trails—including setpoint history, sensor readings, and alarm events—are retained for GLP/GMP-aligned laboratories.

Software & Data Management

Control and monitoring are managed through inTEST’s proprietary ThermoStream Control Software (v5.x), compatible with Windows 10/11 64-bit platforms. The software provides real-time graphical visualization of temperature vs. time profiles, configurable multi-step test sequences, and automated pass/fail evaluation against user-defined limits. Data export is supported in CSV, XML, and PDF formats; raw logs include timestamps with microsecond resolution. For regulated environments, optional 21 CFR Part 11-compliant configuration includes electronic signatures, role-based access control, and immutable audit trail generation. Remote diagnostics and firmware updates are performed securely over HTTPS with TLS 1.2 encryption.

Applications

• Qualification testing of semiconductor devices per AEC-Q100, JEDEC, and automotive OEM specifications
• Failure analysis root-cause investigation involving solder joint fatigue, delamination, and CTE mismatch effects
• Process validation for lead-free reflow profiles and underfill curing cycles
• Reliability screening of MEMS sensors, power modules, and optoelectronic assemblies
• Pre-compliance thermal stress assessment prior to formal HALT/HASS campaigns
• Research-grade thermal boundary characterization in academic and government labs (e.g., DARPA, NASA, NIST)

FAQ

What distinguishes the ATS-500 from the ATS-700 series?
The ATS-500 line targets benchtop and mid-capacity applications with temperature ranges up to +225 °C and airflow up to 10–12 scfm. The ATS-700 series offers expanded extremes (–100 °C to +300 °C), higher flow capacity (up to 18 scfm), and structural enhancements for continuous industrial operation.
Is calibration certification included with shipment?
Yes—each unit ships with a factory-issued NIST-traceable calibration certificate covering temperature uniformity, stability, and ramp rate verification at three points across the operating range.
Can the system be integrated into an existing test automation framework?
Absolutely—the ATS platform supports SCPI command sets over Ethernet (TCP/IP) and USB-VCOM interfaces, enabling seamless integration with LabVIEW, Python-based test sequencers, and MES/SCADA systems.
Does inTEST provide application engineering support for test method development?
Yes—authorized distributors such as Shanghai Boydong offer application consulting, test protocol review, and on-site setup assistance aligned with industry-specific qualification standards.
