Overview
The inTEST Temptronic ThermoStream ATS-505E is a high-speed, benchtop thermal shock test system engineered for precision temperature transient testing of electronic components and printed circuit assemblies. Unlike conventional environmental chambers, the ATS-505E employs a forced-air convective thermal stream delivery mechanism—based on closed-loop thermoelectric and compressor-assisted cooling with integrated heating—to generate rapid, localized thermal excursions directly onto device-under-test (DUT) surfaces. Its core architecture eliminates reliance on cryogenic media such as liquid nitrogen (LN₂) or liquid CO₂, enabling safe, repeatable, and environmentally compliant operation with zero ozone-depleting refrigerants. Designed specifically for semiconductor validation labs, reliability engineering teams, and failure analysis facilities, the system delivers calibrated thermal transients across a wide operational envelope (−20°C to +225°C) while maintaining real-time feedback control and NIST-traceable accuracy.
Key Features
- High-fidelity thermal streaming: Delivers stable, laminar airflow at 4–10 SCFM (1.9–4.7 L/s) with programmable velocity and directionality for targeted DUT exposure.
- Ultra-fast ramp rates: Achieves ≤3 minutes from 0°C to +125°C and ≤4 minutes from +125°C to 0°C—enabling accelerated thermal cycling per JEDEC JESD22-A104 and A110 standards.
- NIST-traceable temperature control: ±1°C accuracy over full range, with 0.1°C display resolution and dual-point calibration verification capability.
- Intelligent safety architecture: Factory-set overtemperature limit at +230°C; user-configurable upper/lower bounds with hardware-enforced cutoff and audible/visual fault indication.
- Modular service design: Field-replaceable thermal modules, airflow sensors, and controller boards minimize downtime and support GLP-compliant maintenance logs.
- Integrated diagnostics: Self-test routines, error-code reporting, and real-time status monitoring via front-panel LCD and remote interfaces.
Sample Compatibility & Compliance
The ATS-505E accommodates a broad spectrum of electronic test configurations—including bare die, packaged ICs (QFN, BGA, SOIC), PCB-mounted devices, and load-board-mounted DUTs—without requiring chamber evacuation or mechanical repositioning. Its focused thermal stream enables selective stress application to individual components on densely populated boards, preserving thermal integrity of adjacent devices—a critical capability for failure isolation in mixed-technology assemblies. The system complies with IEC 60068-2-14 (change of temperature), MIL-STD-810H Method 503.5, and supports audit-ready operation under ISO/IEC 17025 and FDA 21 CFR Part 11 when paired with validated software configurations. All refrigerants meet EPA SNAP program requirements and contain zero CFCs, HCFCs, or flammable hydrocarbons.
Software & Data Management
Remote operation is supported via IEEE-488 (GPIB) and RS-232 serial protocols, enabling seamless integration into automated test environments using LabVIEW, Python, or custom SCPI command sets. In-house-developed ThermoStream Control Software (v4.x) provides graphical waveform editing, multi-segment profile sequencing, real-time temperature overlay, and timestamped data export in CSV and TDMS formats. Audit trails record all parameter changes, calibration events, and system faults with operator ID and UTC timestamps—fully satisfying GLP/GMP documentation requirements. Optional Ethernet interface and OPC UA server enable enterprise-level traceability within MES and QMS platforms.
Applications
- Qualification testing of ASICs, FPGAs, power modules, and automotive-grade SoCs per AEC-Q100 stress profiles.
- Thermal validation of solder joint reliability under repeated thermal shock (e.g., IPC-9701).
- Failure mode identification during early-life screening (burn-in) and latent defect activation.
- Thermal boundary condition simulation for thermal modeling correlation (e.g., ANSYS Icepak, FloTHERM).
- Pre-compliance testing for JEDEC JESD22-A104 (Temperature Cycling) and JESD22-A106 (Thermal Shock).
- On-bench characterization of thermal interface materials (TIMs) and heatsink performance under dynamic loading.
FAQ
Does the ATS-505E require external chiller or LN₂ supply?
No. It integrates a self-contained refrigeration system with non-ozone-depleting R-513A refrigerant and resistive heating elements—no external cryogens or chilled water loops are needed.
Can the system perform temperature cycling with dwell times?
Yes. Profiles support up to 999 segments with programmable dwell, ramp rate, and endpoint hold—fully compliant with JEDEC-defined thermal cycling test methods.
Is NIST calibration documentation included with shipment?
Each unit ships with a NIST-traceable calibration certificate covering temperature accuracy and sensor linearity across the full operating range.
What thermocouple types are supported for DUT monitoring?
T-type and K-type thermocouples are natively supported; third-party probes with standard miniature connectors may be integrated via configurable input scaling.
How is system validation performed for regulated environments?
IQ/OQ documentation packages—including installation checklists, operational verification scripts, and uncertainty budgets—are available upon request for GxP-regulated deployments.
