LabCompanion TC/TH Series Fast Temperature Cycle Test Chamber

Overview

The LabCompanion TC/TH Series Fast Temperature Cycle Test Chamber is an engineered environmental stress screening (ESS) system designed for accelerated thermal reliability validation of electronic components, printed circuit assemblies (PCBAs), automotive modules, and aerospace subsystems. Based on forced-air convection with dual independent refrigeration and heating circuits, the chamber delivers rapid, repeatable thermal transitions under tightly controlled conditions—enabling precise simulation of real-world thermal cycling profiles encountered during operational life or transportation. Unlike conventional high-low temperature chambers, this series emphasizes dynamic thermal ramping performance, supporting standardized test protocols such as JEDEC JESD22-A104 (Temperature Cycling), MIL-STD-810H Method 503.5 (Temperature Shock), and IEC 60068-2-14 (Change of Temperature). Its compact footprint (500 × 600 × 500 mm internal volume) makes it especially suitable for R&D labs, quality assurance departments, and small-batch qualification testing where space efficiency and cycle time reduction are critical.

Key Features

• High-speed thermal transition capability: Programmable heating rates from 5 to 20 °C/min and cooling rates ≥5 °C/min—achievable across the full operating range of −70 °C to +150 °C.
• Precision climate control architecture: Dual PID-controlled heating and refrigeration systems with independent air circulation paths ensure stable setpoint maintenance and minimal overshoot.
• Thermal uniformity and stability: Achieves ±2.0 °C temperature uniformity and ±0.5 °C fluctuation over time—validated per GB/T 10592–2008 and traceable to national metrological standards.
• Robust structural design: Stainless steel inner chamber, double-layer insulated door with magnetic seal, and corrosion-resistant exterior housing for long-term operational integrity.
• Integrated safety protection: Over-temperature, over-pressure, compressor overload, and phase failure monitoring with automatic shutdown and audible/visual alarm.
• Patented airflow optimization (Patent No. ZL201520544064.8): Ensures homogeneous temperature distribution without hot/cold spots—even during rapid ramp phases.

Sample Compatibility & Compliance

The TC/TH chamber accommodates standard test specimens up to 30 kg (distributed load) and supports mounting fixtures for PCBs, IC packages, sensors, connectors, and small mechanical subassemblies. It is fully compliant with major international and national environmental testing standards—including GB/T 2423.1–2008 (Cold), GB/T 2423.2–2008 (Dry Heat), GB/T 2423.3–2006 (Damp Heat, Steady State), and GB/T 10592–2008 (Performance Requirements for Climate Chambers). While not intrinsically explosion-proof, optional modifications (e.g., purge systems, spark-proof components) can be implemented upon request for ATEX Zone 2 or Class I Div 2 environments. All units undergo factory calibration and come with a documented as-built verification report.

Software & Data Management

Equipped with LabCompanion’s proprietary TEMPera™ control software, the chamber supports multi-segment thermal profiling, real-time data logging (≥1 Hz sampling), and automated report generation in PDF/CSV formats. The interface complies with GLP/GMP documentation requirements: user access levels, electronic signatures, audit trail logging, and FDA 21 CFR Part 11–compatible data integrity features are available via optional firmware upgrade. Remote monitoring and control are enabled via Ethernet (TCP/IP) or RS485 Modbus RTU, facilitating integration into centralized lab management systems (LIMS) or MES platforms.

Applications

• Accelerated life testing of solder joints, wire bonds, and die attach interfaces in semiconductor packaging.
• Qualification of automotive ECUs, ADAS sensors, and battery management systems (BMS) per ISO 16750-4 and AEC-Q200.
• Reliability screening of medical electronics subject to IEC 60601-1 environmental clauses.
• Material compatibility studies for conformal coatings, encapsulants, and adhesives under cyclic thermal stress.
• Pre-compliance verification prior to third-party certification at accredited test houses (e.g., UL, TÜV, SGS).

FAQ

What is the difference between TC-series and TH-series models?

The TC-series is configured for dry thermal cycling only; the TH-series integrates humidity control (10–98% RH) and meets GB/T 10586–2006 for combined temperature-humidity cycling.
Can the chamber be integrated into an automated test cell?

Yes—standard Modbus RTU and optional Ethernet/IP communication protocols enable seamless integration with PLC-based test sequencers and robotic handlers.
Is calibration certificate included with shipment?

A factory-issued calibration report (traceable to CNAS-accredited reference standards) is provided; ISO/IEC 17025-certified calibration services are available upon request.
What maintenance intervals are recommended?

Refrigerant circuit inspection every 12 months; air filter replacement every 3 months; full system verification annually or after 500 operational cycles.
Does LabCompanion offer extended warranty or service contracts?

Yes—comprehensive 3-year parts-and-labor warranty is standard; extended coverage (up to 5 years) and on-site preventive maintenance plans are available globally through authorized service centers in Shanghai, Wuhan, Chengdu, Xi’an, and Hong Kong.
