Overview
The inTEST ThermoStream® ATS-750 is a high-speed, localized thermal shock test system engineered for precision temperature cycling and transient thermal stress validation of electronic components, integrated circuits (ICs), PCB assemblies, and semiconductor packages. Unlike conventional environmental chambers that rely on bulk air volume conditioning, the ATS-750 employs a forced-convection, closed-loop gas stream delivery architecture—based on inTEST’s proprietary Optimized Control Module (OCM) technology—to deliver rapid, repeatable, and spatially targeted thermal transients directly onto device-under-test (DUT) surfaces. Its core operational principle leverages high-mass-flow, low-inertia airflow combined with real-time thermocouple feedback (T- or K-type) and adaptive PID control to achieve sub-10-second transitions between −55 °C and +125 °C—enabling accelerated reliability testing per JEDEC JESD22-A104 (Temperature Cycling), JESD22-A106 (Thermal Shock), and MIL-STD-883 Method 1010.8.
Key Features
- Ultra-fast thermal transition: Achieves −55 °C ↔ +125 °C in approximately 10 seconds, enabling high-throughput qualification of ICs and advanced packaging (e.g., SiP, Fan-Out, 3D-IC).
- NIST-traceable temperature accuracy of ±1 °C across full operating range (−85 °C to +300 °C), verified at point-of-use via calibrated thermocouple input.
- Dual-mode operation: “Air Mode” for ambient reference calibration; “DUT Mode” for closed-loop, sensor-in-the-loop control using embedded or surface-mounted thermocouples on the device itself.
- Modular mechanical interface options: Includes handheld thermal nozzle, adjustable benchtop stand, and optionally the ATS-750E-M robotic arm integration kit for automated wafer-level or board-level thermal mapping.
- Legacy-free control architecture: Embedded Linux-based controller with touchscreen HMI eliminates Windows OS dependencies—ensuring long-term firmware stability, cybersecurity compliance, and uninterrupted support lifecycle.
- Energy-optimized thermal management: Intelligent frost mitigation via auto-defrost cycles; low-power standby mode; and dynamic compressor load modulation during hold phases.
- Comprehensive I/O and protocol support: Native IEEE-488 (GPIB), RS-232, and Ethernet (TCP/IP) interfaces—fully compatible with LabVIEW™, Python pyVISA, and industry-standard test executive platforms (e.g., NI TestStand, Keysight PathWave).
Sample Compatibility & Compliance
The ATS-750 is designed for non-contact, localized thermal stimulation of electrically active or passive devices mounted on load boards, burn-in sockets, probe cards, or bare die handlers. It accommodates DUTs ranging from 0402 passives to large-format ASICs and multi-chip modules (MCMs), with no physical enclosure constraints. Its open-stream design avoids condensation-related failure modes common in sealed chamber systems—critical for moisture-sensitive devices (MSL 1–3) and underfill-cured substrates. The system complies with CE marking requirements (2014/30/EU EMC Directive, 2014/35/EU LVD), RoHS 2011/65/EU, and supports FDA 21 CFR Part 11 compliance when paired with inTEST’s optional SecureLog™ data integrity module (audit trail, electronic signatures, role-based access). All temperature calibrations are traceable to NIST standards per ISO/IEC 17025-accredited procedures.
Software & Data Management
The embedded ThermoStream Control Suite provides real-time waveform visualization, scriptable test sequencing (via ASCII command set), and synchronized logging of DUT temperature, airflow setpoint, compressor status, and thermocouple voltage. Export formats include CSV, TDMS, and XML—structured for direct ingestion into statistical process control (SPC) platforms and failure analysis databases. Optional inTEST DataVault™ software adds GLP/GMP-aligned features: user authentication, change history tracking, electronic batch records, and encrypted archival compliant with ISO 13485 and ICH Q9. Remote monitoring and alarm notification (email/SNMP) are supported over standard TCP/IP networks without third-party middleware.
Applications
- JEDEC-compliant thermal shock qualification of automotive-grade AEC-Q100 devices.
- Thermal boundary characterization of advanced packaging (e.g., thermal interface material efficacy, solder joint fatigue modeling).
- Dynamic thermal validation of power electronics (SiC/GaN MOSFETs, IGBTs) under realistic switching duty cycles.
- Failure root cause analysis (RCA) via controlled thermal stress induction on suspect nodes identified by IR thermography or EMMI.
- Design verification of thermal management solutions—including heat spreaders, vapor chambers, and microchannel cold plates—under transient loading conditions.
- Reliability screening for space-grade components per ECSS-Q-ST-30-15C and NASA GEVS requirements.
FAQ
What distinguishes the ATS-750 from traditional thermal shock chambers?
Unlike insulated cabinet-style chambers relying on thermal mass exchange, the ATS-750 delivers rapid, localized heating/cooling via directed gas flow—eliminating thermal lag, minimizing cross-talk between adjacent components, and enabling single-DUT stress without affecting neighboring devices on the same board.
Is the ATS-750 suitable for production floor deployment?
Yes. Its solid-state control architecture, minimal maintenance footprint (no liquid nitrogen or cryogenic consumables), and CE/UL certification support Class 1000 cleanroom and high-volume manufacturing environments.
Can the system be integrated into automated test equipment (ATE) platforms?
Absolutely. Standard GPIB, RS-232, and Ethernet interfaces—with documented SCPI-compatible command syntax—enable seamless integration with Teradyne, Advantest, and custom handler-based test systems.
Does inTEST provide calibration and service support outside the U.S.?
Yes. As an ISO 9001:2015 certified manufacturer, inTEST maintains authorized service centers in Europe, Asia, and North America—with on-site calibration, preventive maintenance contracts, and spare parts logistics aligned to IATF 16949 requirements.
