Overview
The KS-TH Series Rapid Temperature Change Environmental Test Chamber is an engineered thermal stress test system designed for evaluating the reliability and functional integrity of electronic components, electrical instruments, automotive modules, aerospace subsystems, and advanced materials under accelerated thermal cycling conditions. It operates on the principle of controlled, high-rate temperature transition between predefined extremes—typically ranging from –70 °C to +180 °C—while maintaining precise chamber uniformity (±1.0 °C) and stability (±0.5 °C) per IEC 60068-2-14 and MIL-STD-810H methodologies. Unlike standard thermal chambers, the KS-TH series achieves ramp rates up to 15 °C/min (depending on model and load), enabling rapid thermal shock simulation without mechanical specimen transfer. Its dual-refrigerant cascade refrigeration architecture—utilizing R404A for primary cooling and R23 for deep sub-zero stages—ensures consistent performance across the full operational envelope, even under continuous cyclic operation. The chamber’s structural design prioritizes thermal inertia minimization and air distribution optimization, supporting both steady-state and dynamic thermal profile execution in accordance with ASTM D5276, ISO 16750-4, and JEDEC JESD22-A104 qualification protocols.
Key Features
- High-strength SUS304B stainless steel construction for exterior enclosure and interior test space—welded using helium-leak-tested, gas-tight TIG processes to ensure long-term corrosion resistance and vacuum-grade sealing integrity.
- Double-layer silicone rubber door gasket system combined with mineral wool insulation (≥100 mm thickness) between outer shell and working chamber—achieving low thermal conductivity (<0.04 W/m·K) and minimizing energy loss during extreme temperature transitions.
- Adjustable stainless steel sample shelves with reinforced support rails—compatible with standard test fixtures and accommodating specimens up to 30 kg per shelf (load capacity varies by model).
- Dual axial-flow circulation fans (quantity dependent on chamber volume)—mounted to optimize laminar airflow and reduce vertical/horizontal temperature gradients to ≤1.5 °C across the working volume per IEC 60068-3-5.
- Standard 50 mm diameter cable port on left side wall—fitted with removable blanking plug and optional feedthrough adapters for thermocouple, power, or signal line integration.
- TEMI880 intelligent controller with 7-inch color TFT touchscreen—featuring intuitive icon-driven navigation, real-time trend graphing, alarm logging, and password-protected parameter access control.
Sample Compatibility & Compliance
The KS-TH chamber accommodates a broad range of sample types—including PCB assemblies, semiconductor packages, battery cells, optical sensors, and polymer composites—without requiring internal modifications. All models comply with safety and electromagnetic compatibility requirements per EN 61000-6-2/6-4 and are CE-marked for use in EU-based laboratories. For regulated environments, the TEMI880 controller supports audit-trail-enabled operation when configured with optional firmware upgrade (compliant with FDA 21 CFR Part 11 data integrity principles). Chamber validation documentation—including IQ/OQ templates, temperature mapping reports (per ISO/IEC 17025), and uncertainty budgets—is available upon request for GLP/GMP-aligned quality systems.
Software & Data Management
The TEMI880 controller provides native program storage for up to 100 user-defined thermal profiles, each supporting up to 1000 sequential steps—including ramp, soak, hold, and jump functions—with programmable rate limits, dwell times, and conditional branching logic. Real-time data logging records temperature, setpoint, and alarm status at configurable intervals (1–60 s), exporting timestamped CSV files via USB or RS232-C interface. Optional PC-based software (KS-LogView) enables remote monitoring, multi-chamber synchronization, statistical process analysis (SPC), and automated report generation compliant with ISO 9001 clause 8.5.2. All logged data retains immutable timestamps and operator ID tags, satisfying traceability requirements for internal QA audits and third-party certification bodies.
Applications
This chamber is routinely deployed in failure analysis labs for identifying solder joint fatigue, delamination in multilayer substrates, coefficient-of-thermal-expansion (CTE) mismatch failures, and encapsulant cracking in optoelectronic devices. It serves as a core tool in AEC-Q200 stress qualification for passive components and supports accelerated life testing per Telcordia GR-468-CORE for telecom hardware. Academic research applications include investigating phase-transition behavior in shape-memory alloys and thermal aging kinetics in lithium-ion battery electrolytes. Industrial users leverage its reproducible thermal cycling capability for incoming inspection screening, burn-in verification, and supplier qualification programs aligned with IPC-9701 and IATF 16949 clause 8.5.1.2.
FAQ
What is the maximum achievable temperature transition rate?
Ramp rates depend on chamber model, ambient conditions, and thermal load—but typically reach 10–15 °C/min between –40 °C and +85 °C with empty chamber and nominal airflow settings.
Can the chamber operate in humidity-controlled mode?
No—the KS-TH series is a dry thermal cycling chamber only. For combined temperature-humidity stress testing, refer to the KS-THH variant (not covered here).
Is calibration certificate included with shipment?
A factory-as-built temperature uniformity report is provided. NIST-traceable calibration certificates (per ISO/IEC 17025) are available as optional add-ons.
How is over-temperature protection implemented?
Independent mechanical high-limit thermostat (cut-off at +200 °C) plus digital sensor redundancy—both triggering immediate compressor shutdown and audible/visual alarms.
What maintenance intervals are recommended?
Compressor oil and refrigerant levels should be verified annually; air filter cleaning every 3 months; door gasket inspection and replacement every 24 months under continuous operation.
