LabCompanion TH-800-10 Rapid Temperature Transition Stress Screening Chamber

Overview

The LabCompanion TH-800-10 Rapid Temperature Transition Stress Screening Chamber is an engineered environmental test system designed for accelerated reliability evaluation of electronic components, aerospace assemblies, automotive ECUs, and high-value PCBs under extreme thermal cycling conditions. It operates on a forced-air convection principle with dual independent refrigeration and heating circuits, enabling precise, repeatable, and programmable temperature transitions across its full operating range of −70 °C to +150 °C. Unlike standard thermal chambers, the TH-800-10 supports both linear and non-linear ramp profiles—critical for simulating real-world thermal shock events such as power-on/power-off cycles, altitude-induced ambient shifts, or rapid climate transitions during field deployment. Its architecture complies with the mechanical and thermal stability requirements outlined in IEC 60068-2-14 (Test N: Change of Temperature) and ASTM F1876 (Standard Practice for Thermal Cycling of Electronic Components). The chamber is intended for use in qualification testing, HALT/HASS pre-screening, and process validation within ISO/IEC 17025-accredited laboratories.

Key Features

• High-fidelity temperature control with ±0.5 °C fluctuation tolerance and ≤2.0 °C uniformity across the full working volume—verified per IEC 60068-3-5
• Programmable ramp rates from 1 to 25 °C/min, supporting both linear sweeps and custom-defined non-linear thermal profiles via embedded controller
• Robust dual-circuit refrigeration system using environmentally compliant R404A/R23 cascade configuration for stable sub-zero operation down to −70 °C
• Stainless-steel interior chamber (1000 × 1000 × 800 mm) with reinforced insulated walls, seamless welds, and anti-condensation heating on observation windows
• Integrated safety interlocks including over-temperature cut-off, refrigerant pressure monitoring, door-open alarm, and emergency stop circuitry compliant with EN 61000-6-2/6-4
• Touchscreen HMI with real-time graphing, data logging at configurable intervals (1–60 s), and USB export capability for post-test analysis

Sample Compatibility & Compliance

The TH-800-10 accommodates large-format test specimens—including 19-inch rack-mounted systems, battery modules up to 30 kg, and multi-layer automotive harness assemblies—without compromising thermal homogeneity. Its internal volume permits simultaneous placement of multiple DUTs (Devices Under Test) with adequate airflow clearance, satisfying MIL-STD-810H Method 503.5 (Temperature Shock) sample spacing guidelines. The chamber meets structural and operational requirements for GLP-compliant environments and supports audit-ready documentation when paired with optional external data acquisition systems. All electrical interfaces conform to UL 61010-1 and CE marking directives. Calibration traceability is maintained to NIST-traceable standards through factory-certified temperature mapping reports (per ISO/IEC 17025 Annex A.4).

Software & Data Management

The embedded controller runs LabCompanion’s proprietary TC-OS v4.2 firmware, offering intuitive profile creation, step-loop nesting, and conditional branching (e.g., “hold until sensor T1 ≥ 120 °C”). Optional Ethernet connectivity enables integration with enterprise LIMS platforms and centralized test management systems via Modbus TCP or OPC UA protocols. When configured with the LabCompanion DataBridge Module, the system generates 21 CFR Part 11–compliant audit trails—including user login history, parameter change logs, and timestamped event records—with digital signature support. Raw temperature/time datasets are exported in CSV or MATLAB-compatible .mat format, facilitating statistical process control (SPC) analysis and Weibull reliability modeling.

Applications

• Pre-production stress screening of solder joints, conformal coatings, and MEMS packaging per IPC-9701A
• Thermal fatigue assessment of power semiconductor modules used in EV inverters and renewable energy converters
• Validation of thermal interface materials (TIMs) under dynamic load cycling conditions
• Qualification testing of avionics enclosures subjected to rapid stratospheric descent profiles
• Accelerated aging studies for polymer-based medical device housings per ISO 10993-12
• Supporting failure mode identification in root cause analysis (RCA) workflows for field return investigations

FAQ

What is the maximum thermal ramp rate achievable across the full temperature range?

The TH-800-10 achieves 25 °C/min between −40 °C and +85 °C under no-load conditions; ramp performance may vary slightly near extremes (e.g., −70 °C or +150 °C) due to thermodynamic constraints.

Does the chamber support automated thermal shock testing per JEDEC JESD22-A106?

Yes—when equipped with the optional dual-zone thermal shock adapter kit, the system executes two-chamber shock protocols with transfer times <15 s, meeting JESD22-A106B requirements.

Can temperature mapping be performed internally without third-party equipment?

The chamber includes 9 fixed calibration ports (per IEC 60068-3-5 Annex B) and supports plug-in thermocouple arrays; full 16-point mapping reports can be generated using the built-in mapping utility.

Is remote monitoring and control supported out of the box?

Standard Ethernet port enables basic SNMP status polling and FTP-based log retrieval; full remote supervision requires optional LabCompanion RemoteView License.

What maintenance intervals are recommended for the refrigeration system?

Compressor oil and filter-drier replacement is advised every 24 months or 8,000 operating hours—whichever occurs first—under normal usage conditions per manufacturer service bulletin SB-TH800-REV7.
