inTEST Temptronic ThermoStream ATS Series Thermal Shock Test System

Overview

The inTEST Temptronic ThermoStream ATS Series is a high-performance, gas-based thermal shock test system engineered for precision temperature stimulation of individual semiconductor devices and integrated circuits during automated test equipment (ATE) operation. Unlike conventional environmental chambers that thermally condition entire assemblies, the ThermoStream delivers localized, dynamic thermal energy directly to device-under-test (DUT) surfaces via focused, laminar nitrogen or compressed air streams—enabling real-time, closed-loop thermal control at the component level. Its core measurement principle relies on rapid convective heat transfer governed by mass flow-controlled gas delivery, high-resolution thermocouple feedback, and PID-driven thermal regulation. Designed specifically for reliability validation, failure analysis, and parametric characterization in semiconductor manufacturing and R&D labs, the ATS platform supports full integration into production-grade ATE environments—including Advantest V93000, Teradyne UltraFLEX, and Verigy 93000 platforms—without requiring chamber door opening or DUT removal.

Key Features

• Ultra-fast thermal ramp rates up to 18 °C per second—achievable across the full operational range of –100 °C to +300 °C
• Device-level thermal targeting: isolates single ICs, packages, or die on populated PCBs without affecting adjacent components
• Real-time temperature monitoring via integrated Type T thermocouples with ±1 °C stability under steady-state and transient conditions
• Modular ATS head design compatible with standard load boards and probe cards; supports both horizontal and vertical DUT orientation
• Gas stream temperature modulation synchronized with ATE test sequences via digital I/O and Ethernet (TCP/IP) interfaces
• Robust architecture compliant with SEMI S2/S8 safety standards and designed for 24/7 operation in Class 1000 cleanroom environments

Sample Compatibility & Compliance

The ThermoStream ATS accommodates a wide spectrum of electronic test specimens—including bare die, wire-bonded and flip-chip packaged ICs (QFN, BGA, LGA), RF transceivers, optoelectronic modules, and multi-die heterogeneous integration substrates. It operates within defined thermal boundaries per JEDEC JESD22-A104 (Temperature Cycling) and JESD22-A106 (Thermal Shock), and supports test profiles aligned with MIL-STD-883 Method 1010 and AEC-Q200 stress requirements. All ATS systems are manufactured in accordance with ISO 9001:2015 quality management systems and include documentation traceable to NIST-traceable calibration standards. For regulated environments, optional audit trail logging and user access control modules meet FDA 21 CFR Part 11 and GLP/GMP data integrity requirements.

Software & Data Management

The ThermoStream Control Software (TCS v5.x) provides intuitive graphical configuration of thermal profiles, including step, ramp, dwell, and custom waveform definitions. It enables bidirectional communication with ATE handlers and testers through industry-standard protocols such as STDF, SECS/GEM, and SCPI over TCP/IP or RS-232. All temperature setpoints, actual readings, gas flow rates, and alarm events are timestamped and logged in CSV-compatible format with millisecond resolution. Optional TCS-Enterprise Edition adds centralized fleet management, remote diagnostics, role-based user permissions, and automated report generation compliant with ISO/IEC 17025 reporting guidelines.

Applications

• High-speed thermal cycling for burn-in and accelerated life testing of ASICs, FPGAs, and memory devices
• Thermal mapping and hotspot identification during functional test execution
• Failure mode isolation in early-life reliability screening (ELFR) and infant mortality analysis
• Characterization of thermal coefficient of resistance (TCR), threshold voltage shift (Vth), and leakage current vs. temperature
• Validation of thermal interface materials (TIMs) and package-level thermal performance under dynamic load conditions
• Support for JEDEC-compliant HAST, uHAST, and THB preconditioning prior to electrical testing

FAQ

What distinguishes ThermoStream from traditional thermal chambers?
Unlike ambient-volume chambers, ThermoStream applies thermal energy directly to the DUT surface using controlled gas flow—eliminating thermal inertia, enabling sub-second response, and avoiding thermal cross-talk between adjacent components.
Can ThermoStream be integrated with existing ATE hardware?
Yes. The ATS series offers native support for Advantest, Teradyne, and Verigy platforms via programmable digital I/O, Ethernet APIs, and handler-compatible mounting kits.
Is NIST-traceable calibration documentation available?
Each system ships with factory calibration certificates traceable to NIST standards; annual recalibration services are offered through inTEST-certified service centers globally.
What gases are supported for operation?
Standard operation uses dry nitrogen or instrument-grade compressed air; optional liquid nitrogen (LN2) assist is available for extended low-temperature capability down to –100 °C.
Does the system comply with cleanroom requirements?
All ATS models are rated for continuous use in ISO Class 6 (Class 1000) environments and feature non-outgassing materials, filtered exhaust paths, and static-dissipative construction.
