LabCompanion TH-600 Linear Rapid Temperature Change Chamber

Overview

The LabCompanion TH-600 Linear Rapid Temperature Change Chamber is an engineered environmental test system designed for high-fidelity thermal stress evaluation of electronic components, automotive modules, aerospace subsystems, and packaging materials. It operates on a dual-stage compressor refrigeration architecture with precision PID-controlled heating and forced-air convection circulation, enabling reproducible linear temperature transitions across its full operational range of −70 °C to +150 °C. Unlike stepped or dwell-based thermal cycling systems, the TH-600 implements true linear ramp control—programmable at discrete rates from 1 °C/min up to 25 °C/min (standard configuration), with optional liquid nitrogen (LN₂) auxiliary injection supporting transient cooling rates up to 30 °C/min for accelerated reliability qualification per MIL-STD-810H Method 503.5 and JEDEC JESD22-A104F. The chamber’s structural integrity, thermal mass distribution, and airflow dynamics are validated against ISO 16750-4 (Road Vehicles – Environmental Conditions) and IEC 60068-2-14 (Change of Temperature) requirements.

Key Features

• Linear temperature ramping capability with programmable rate selection (1–25 °C/min standard; up to 30 °C/min with LN₂ option)
• High-stability temperature control: ±0.5 °C fluctuation, ±2.0 °C uniformity, and ±2.0 °C deviation across the full working volume
• Robust stainless-steel inner chamber (SUS304) with insulated double-wall construction and silicone-sealed door gasket
• Dual independent sensor monitoring: one for control loop feedback, one for independent verification and data logging
• Touchscreen HMI with embedded real-time graphing, multi-segment profile programming, and USB export of test logs
• Compressor-based primary cooling with cascade design for low-temperature stability below −40 °C
• Integrated over-temperature, over-pressure, and refrigerant leak detection with automatic shutdown and alarm relay output

Sample Compatibility & Compliance

The TH-600 accommodates samples up to 100 kg (static load) with unrestricted access via front-mounted double-door configuration. Its internal dimensions (1020 × 860 × 670 mm W×H×D) support standard IPC/JEDEC trays, automotive ECUs, PCB assemblies, and molded plastic housings. All thermal performance metrics—including fluctuation, deviation, and uniformity—are verified per GB/T 5170.2–2008 and traceable to national metrology standards. The system supports audit-ready operation under GLP and GMP environments through configurable user access levels, electronic signature support, and event-driven audit trail generation. Optional calibration certificates (NIST-traceable) and IQ/OQ documentation packages are available upon request.

Software & Data Management

The embedded controller runs LabCompanion’s TC-Studio firmware, offering intuitive profile creation with up to 99 segments, conditional branching (e.g., “hold until sensor A reaches target”), and real-time deviation alerts. Data is logged at user-selectable intervals (1 s to 60 min) and stored internally (≥10,000 hours of continuous data). Export options include CSV, PDF reports, and direct Ethernet transmission to enterprise LIMS or MES platforms. For regulatory compliance, optional 21 CFR Part 11-compliant software adds role-based authentication, electronic signatures, and immutable audit logs with time-stamped operator actions and parameter modifications.

Applications

• Thermal shock screening of solder joints and interconnects per IPC-9701A
• Qualification testing of battery management systems (BMS) under rapid ambient transients
• Validation of polymer-based medical device housings per ISO 10993-12
• Environmental stress screening (ESS) in electronics manufacturing per ANSI/GEIA-STD-0006
• Material coefficient of thermal expansion (CTE) correlation studies using synchronized thermography
• Pre-conditioning of sensors and optical assemblies prior to functional testing

FAQ

What is the difference between linear and non-linear temperature ramping in this chamber?

Linear ramping maintains a constant rate of temperature change (e.g., exactly 5 °C/min) throughout the transition, ensuring consistent thermal loading for failure mechanism analysis. Non-linear ramps follow predefined time-temperature curves, often used for simulating real-world ambient profiles.
Can the TH-600 perform humidity-controlled thermal cycling?

No—the TH-600 is a dry-thermal-only chamber. Models with humidity capability (e.g., TH-600H) are available separately and comply with IEC 60068-2-78 for damp heat testing.
Is LN₂ integration factory-installed or field-upgradable?

LN₂ auxiliary cooling is a factory-configured option requiring dedicated plumbing, pressure regulation, and safety interlocks; it is not retrofittable in the field.
How is temperature uniformity verified inside the working volume?

Uniformity is measured using nine calibrated PT100 sensors positioned at standardized locations (center, six face centers, and two corners) per GB/T 5170.2–2008 Annex B during steady-state operation at −40 °C, +25 °C, and +85 °C.
Does the system support remote monitoring and control via Ethernet or Modbus?

Yes—standard Ethernet (TCP/IP) interface supports SCPI command set and Modbus TCP register mapping for integration into centralized facility monitoring systems.
