TS Thermal Shock Test Chamber TS2/TS3

Overview

The TS Thermal Shock Test Chamber TS2/TS3 is an electromechanically actuated, dual-zone thermal shock system engineered for rapid, repeatable transitions between extreme temperature extremes. It operates on the principle of horizontal or vertical specimen transfer between isolated high-temperature and low-temperature chambers—eliminating reliance on single-chamber ramping and thereby achieving significantly faster thermal transition kinetics. This architecture enables precise simulation of real-world thermal stress events encountered during product lifecycle phases such as solder reflow, automotive under-hood operation, aerospace component deployment, and electronic packaging qualification. The chamber meets core requirements of MIL-883E Method 1010.8 (Thermal Shock), IEC 60068-2-14 (Change of Temperature), and JIS C 60068-2-14, supporting both air-to-air and component-level thermal shock protocols in accordance with industry-standard qualification test plans.

Key Features

• Sub-10-second specimen transfer mechanism ensures compliance with stringent thermal shock timing criteria specified in MIL-883E and IEC 60068-2-14;
• Temperature recovery time of 3–5 minutes post-transfer, verified per chamber zone using calibrated Class A PT100 sensors traceable to NIST standards;
• Dual independent refrigeration and heating systems with optimized heat exchanger geometry and insulated chamber walls to minimize energy consumption without compromising thermal stability;
• Compact footprint design accommodates integration into constrained laboratory or production floor environments—chamber models range from 6 L (TS2) to 130 L (TS3) internal volume;
• Robust stainless-steel interior construction with reinforced door seals and positive-pressure purge capability to prevent condensation ingress during low-temperature exposure;
• Programmable controller with Ethernet interface supports remote monitoring, alarm logging, and real-time temperature profiling via Modbus TCP or optional OPC UA protocol.

Sample Compatibility & Compliance

The TS series accommodates test specimens ranging from small PCB assemblies (1.0 kg) to full automotive control units (20.0 kg), with internal chamber dimensions scalable across five standard configurations. Each model maintains uniformity of ±2 °C across the active test zone at steady-state conditions, validated per IEC 60068-3-5. The system is compatible with standardized test fixtures—including thermal mass blocks, DUT mounting plates, and thermocouple feedthrough ports—and supports both unpowered and powered-in-situ testing. All electrical safety components comply with IEC 61010-1; thermal insulation materials meet UL94 V-0 flame rating. Documentation packages include Factory Acceptance Test (FAT) reports, calibration certificates for integrated sensors, and a Declaration of Conformity to EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU.

Software & Data Management

Built-in controller firmware provides ISO/IEC 17025-aligned data integrity features: audit-trail-enabled parameter changes, time-stamped temperature logs with millisecond resolution, and automatic generation of PDF test reports compliant with GLP and GMP documentation requirements. Optional PC-based software (TS-Control Suite v4.x) extends functionality with multi-chamber synchronization, statistical process control (SPC) charting, deviation alerts based on user-defined tolerance bands, and export to CSV, XML, or ASTM E2928-compliant formats. All data storage adheres to FDA 21 CFR Part 11 principles when configured with electronic signature modules and role-based access controls.

Applications

• Qualification of semiconductor devices, MEMS sensors, and LED packages per JEDEC JESD22-A106B;
• Reliability validation of conformal-coated PCBs, battery modules, and EV power electronics;
• Material compatibility testing for adhesives, encapsulants, and thermal interface materials (TIMs);
• Aerospace avionics hardware screening per RTCA DO-160 Section 4.11 (Temperature Shock);
• Automotive component certification against ISO 16750-4 and GMW3172 Thermal Shock requirements;
• Research-grade investigation of intermetallic growth, solder joint fatigue, and coefficient-of-thermal-expansion (CTE) mismatch effects.

FAQ

What is the minimum specimen weight required for valid thermal shock testing?

The system is validated for test loads ≥1.0 kg (TS2 base configuration). Lower masses may induce excessive thermal inertia deviation and require custom validation per IEC 60068-1 Annex B.
Can the chamber operate continuously at its maximum temperature extremes?

Yes—each zone is rated for continuous operation at +200 °C (hot side) and –65 °C (cold side), subject to ambient conditions ≤30 °C and relative humidity ≤80% non-condensing.
Is third-party calibration support available?

Certified calibration services—including on-site sensor verification, chamber uniformity mapping, and uncertainty budgeting—are offered by accredited partners with ISO/IEC 17025 scope covering thermal test equipment.
Does the system support automated test sequencing across multiple shock cycles?

Yes—the controller supports up to 999 programmable cycles with variable dwell times, transition rates, and pass/fail logic triggers linked to external PLC or data acquisition systems.
Are replacement parts and technical documentation available internationally?

Full spare parts catalog, English-language operation manuals, maintenance schematics, and firmware update archives are accessible through authorized regional service centers in North America, EMEA, and APAC regions.
