inTEST-Temptronic ATS-710-M High-Speed Thermal Shock Test System for Semiconductor Device Characterization

Overview

The inTEST-Temptronic ATS-710-M High-Speed Thermal Shock Test System is an engineered thermal transient platform designed specifically for dynamic temperature stress testing of semiconductor devices during reliability qualification, failure analysis, and process validation. Utilizing a closed-loop, high-velocity air impingement architecture, the system delivers rapid, repeatable thermal transients across a wide operational envelope—from cryogenic (-80 °C) to ultra-high temperatures (+225 °C). Its core thermodynamic performance—achieved via dual-stage refrigeration, high-efficiency heating elements, and precision airflow control—enables controlled thermal cycling with ramp rates up to 18 °C per second. This capability is critical for simulating real-world thermal fatigue mechanisms such as intermetallic growth, solder joint cracking, and die attach delamination in IC packages, bare die, and advanced packaging substrates (e.g., Fan-Out WLP, 2.5D/3D SiP). Unlike conventional environmental chambers, the ATS-710-M is purpose-built for device-under-test (DUT)-centric thermal profiling, minimizing thermal mass interference and ensuring direct, low-inertia coupling between the airstream and the semiconductor package.

Key Features

• High-fidelity thermal transient delivery: Achieves ±1 °C temperature accuracy across the full range, validated via NIST-traceable calibration certificates provided with each system.
• Dual-mode operation: Supports both Air Mode (for chamber ambient characterization) and DUT Mode (for direct, sensor-coupled thermal profiling at the device level), enabling correlation between chamber setpoint and actual junction or case temperature.
• Modular thermal interface design: Compatible with standard probe stations, wafer chucks, and custom DUT fixtures—including non-contact IR-compatible configurations and thermocouple-integrated sockets.
• Robust thermal architecture: Features redundant safety interlocks, overtemperature/overpressure cutouts, and real-time thermal runaway detection aligned with IEC 61000-4-29 and SEMI S2-0215 safety guidelines.
• Compact footprint and service-accessible layout: Designed for integration into Class 1000 cleanroom environments and ATE test floors without requiring external chiller or exhaust ducting.

Sample Compatibility & Compliance

The ATS-710-M accommodates a broad spectrum of semiconductor form factors—including bare die (2×2 mm to 35×35 mm), leaded and leadless packages (QFP, QFN, BGA, LGA), MEMS sensors, and optoelectronic modules (VCSELs, photodiodes). It supports JEDEC JESD22-A104 (Temperature Cycling), JESD22-A106 (Thermal Shock), and MIL-STD-883 Method 1010.8 test protocols. All calibration records comply with ISO/IEC 17025 requirements, and system firmware includes configurable audit trail logging to meet FDA 21 CFR Part 11 and EU Annex 11 data integrity expectations for regulated semiconductor manufacturing environments.

Software & Data Management

Controlled via inTEST’s proprietary Temptronic Control Suite (v5.2+), the system provides deterministic test sequencing, real-time thermal profile visualization, and synchronized data capture from up to four external analog inputs (e.g., V_BE, I_CC, junction thermistor signals). Export formats include CSV, MATLAB .mat, and industry-standard STDF for integration with yield management systems (YMS) and statistical process control (SPC) platforms. The software supports password-protected user roles, electronic signatures, and automated report generation compliant with internal quality management systems (QMS) and external auditor requirements.

Applications

• Qualification of new IC designs against AEC-Q100 Grade 0–3 automotive thermal stress requirements.
• Accelerated life testing (ALT) of power modules and GaN/SiC discrete devices under thermal cycling-induced mechanical strain.
• Failure mode identification during early-stage reliability screening—particularly for flip-chip interconnects and underfill void propagation.
• Correlation studies between thermal transient response and electrical parametric drift (e.g., threshold voltage shift, on-resistance hysteresis).
• Support for JEDEC JEP180 and IPC-9701 standards in printed electronics and flexible hybrid circuit qualification.

FAQ

What is the difference between Air Mode and DUT Mode?
Air Mode measures chamber air temperature using a reference RTD; DUT Mode uses a thermocouple or diode sensor mounted directly on the device to report actual surface or junction temperature—critical for correlating thermal stress with electrical behavior.
Does the ATS-710-M support automated test sequencing with external testers?
Yes—it features TTL-triggered start/stop, Ethernet/IP and RS-232 interfaces, and native SCPI command support for seamless integration with ATE platforms (e.g., Teradyne UltraFLEX, Advantest T2000).
Is NIST-traceable calibration included with shipment?
Each unit ships with a full NIST-traceable calibration certificate covering the entire operating range, plus annual recalibration services available under inTEST’s global service agreement program.
Can the system be used for humidity-controlled thermal cycling?
No—the ATS-710-M is a dry-air thermal shock system; for combined temperature/humidity stress, consider the inTEST-Temptronic THS series or complementary desiccated chamber integration.
What maintenance intervals are recommended for optimal ramp-rate performance?
Compressor oil and filter replacement every 2,000 operating hours; annual verification of airflow velocity profiles and thermal uniformity mapping per ASTM E2202-20 guidelines.
