LabCompanion TS Series Thermal Shock Test Chamber

Overview

The LabCompanion TS Series Thermal Shock Test Chamber is an electromechanical environmental test system engineered for rapid, repeatable, and controlled temperature transitions between extreme high- and low-temperature zones. It operates on the two-box (dual-chamber) moving-basket principle—featuring physically isolated hot and cold chambers with a horizontally translating specimen carrier—enabling thermal shock profiles with transition times typically under 15 seconds (as defined per IEC 60068-2-14 and MIL-STD-810H Method 503.5). This architecture eliminates residual heat/cold carryover, ensuring high reproducibility in ΔT ramp rates and minimizing thermal lag. Designed for reliability validation of electronic components, aerospace hardware, automotive ECUs, PCB assemblies, and advanced composite materials, the TS Series subjects test specimens to abrupt thermal excursions—typically ranging from −65 °C to +150 °C—to evaluate resistance to thermally induced mechanical stress, interfacial delamination, solder joint fatigue, and coefficient-of-thermal-expansion (CTE) mismatch failure modes.

Key Features

• Two-box configuration with independent hot and cold chambers, enabling true thermal shock (not cycling) per ASTM D5229/D5229M and JESD22-A104E;
• High-efficiency cascade refrigeration system with environmentally compliant R404A/R23 mixed-refrigerant circuitry;
• Intelligent touch-screen controller (Yudian UT520 series) with Chinese/English bilingual interface, supporting up to 99 programmable segments, 999 cycles, and real-time profile monitoring;
• Uniform airflow design with adjustable multi-directional centrifugal fans and optimized baffle geometry—achieving ±1.5 °C temperature uniformity (per IEC 60068-3-5) across the working volume;
• Integrated safety architecture including over-temperature cut-off, compressor high-pressure/low-pressure protection, phase-sequence monitoring, ground-fault circuit interruption (GFCI), and audible/visual alarm triggers;
• Modular structural frame with stainless-steel inner chamber, polyurethane insulation (≥150 mm thickness), and electrostatically coated steel exterior for long-term corrosion resistance;
• Factory-assembled core system with on-site commissioning and performance verification per ISO/IEC 17025 traceable calibration protocols.

Sample Compatibility & Compliance

The TS Series accommodates test specimens up to 500 mm × 500 mm × 500 mm (W×D×H) in standard configurations, with custom cavity dimensions available upon engineering review. Compatible with standard test fixtures, thermocouple feedthroughs (Type T or K), and non-intrusive IR window options. Fully compliant with international test standards including IEC 60068-2-14 (Change of temperature—Method N: Change of temperature by air), JIS Z 8701-3, GB/T 2423.22–2012, and MIL-STD-810H Method 503.5. Supports GLP/GMP-aligned operation when paired with optional audit-trail-enabled controller firmware (compliant with FDA 21 CFR Part 11 requirements for electronic records).

Software & Data Management

Equipped with LabCompanion’s proprietary TEMPCONTROL™ software suite (Windows-based), the TS Series enables remote monitoring, real-time data logging at user-defined intervals (down to 1-second resolution), automated report generation (PDF/CSV), and secure user-level access control (admin/operator/viewer roles). All temperature logs include timestamped metadata (chamber setpoint, actual sensor readings, alarm status, and actuator states), supporting full traceability for internal QA audits or third-party certification bodies. Optional Ethernet/IP or RS485 Modbus RTU connectivity allows integration into centralized MES or SCADA platforms.

Applications

• Qualification testing of semiconductor packages (QFN, BGA, CSP) per JEDEC J-STD-020;
• Thermal fatigue assessment of solder joints in automotive ADAS modules;
• Reliability screening of battery cells and thermal interface materials (TIMs);
• Validation of hermetic seal integrity in MEMS sensors and optical housings;
• Accelerated aging studies for polymer encapsulants and conformal coatings;
• Process development support for reflow soldering and die-attach curing parameters.

FAQ

What is the typical temperature transition time between chambers?

Standard transition time from low to high temperature (or vice versa) is ≤10 seconds for the nominal working volume, verified via calibrated surface-mounted thermocouples per IEC 60068-3-10.
Can the chamber be integrated into an existing factory automation system?

Yes—via optional Modbus TCP or OPC UA gateway modules, supporting bi-directional command/control and real-time telemetry streaming.
Is calibration documentation provided with shipment?

Each unit ships with a factory calibration certificate (NIST-traceable reference sensors), covering chamber uniformity, stability, and transition performance—valid for 12 months from date of commissioning.
Does the system support unattended overnight operation?

Yes—equipped with robust thermal runaway prevention, redundant safety interlocks, and automatic shutdown on critical fault detection; suitable for extended qualification runs under ISO 9001-controlled environments.
What maintenance intervals are recommended?

Compressor oil and filter replacement every 24 months; refrigerant leak check and sensor verification annually; full preventive maintenance service advised every 18 months by certified LabCompanion field engineers.
