Overview
The Jianhu JH-CTC Series Intelligent Touchscreen Thermal Shock Test Chamber is an engineered solution for accelerated environmental stress testing of electronic components, aerospace materials, automotive parts, and precision optical assemblies. Based on the principle of rapid two-zone or three-zone thermal shock—where test specimens are mechanically transferred between independently controlled high-temperature and low-temperature chambers—the system enables precise simulation of extreme thermal cycling conditions as defined in IEC 60068-2-14, MIL-STD-810H Method 503.5, and GB/T 2423.22. Unlike single-chamber ramp-based systems, the JH-CTC’s dual-compartment architecture ensures true thermal shock profiles with minimal dwell time transition (<15 s), minimizing thermal inertia effects and delivering high reproducibility across repeated cycles. Its industrial-grade touchscreen interface integrates real-time thermocouple monitoring, programmable soak durations, and automatic cycle logging—designed for laboratories requiring traceable, auditable test execution under GLP and ISO/IEC 17025 frameworks.
Key Features
- Industrial 10.1-inch capacitive touchscreen with anti-glare coating, supporting multi-touch gesture navigation and intuitive drag-and-drop test profile editing
- Dual independent refrigeration circuits (high-temp and low-temp zones) using hermetic scroll compressors with R404A/R23 cascade refrigerant system for stable operation down to −70 °C
- Explosion-proof enclosure compliant with GB 3836.1–2010 (equivalent to IEC 60079-0) for safe testing of battery cells, volatile chemical packaging, and pyrotechnic components
- High-precision Pt100 Class A sensors (±0.15 °C accuracy) distributed across chamber walls and payload zone, enabling dynamic temperature uniformity compensation
- Automated basket transfer mechanism with pneumatic actuation and position feedback sensors, ensuring repeatable specimen positioning and minimizing mechanical wear
- Real-time deviation alerting: system triggers visual/audible alarms and halts cycling if temperature deviation exceeds ±2.0 °C beyond setpoint for >30 s
Sample Compatibility & Compliance
The JH-CTC accommodates standard test specimens up to 300 mm × 300 mm × 300 mm (custom configurations available), with load capacity up to 25 kg per cycle. It supports mounting fixtures for PCBs, wafer-level packages, sealed enclosures, and medical device housings. All units ship with factory calibration certificates traceable to NIM (National Institute of Metrology, China) and include full compliance documentation for GB/T 2423.22–2012, IEC 60068-2-14:2016, and ASTM D5229/D5229M. Optional upgrade paths include third-party validation reports (per ISO/IEC 17025) and FDA 21 CFR Part 11-compliant audit trail modules for regulated pharmaceutical and biotech applications.
Software & Data Management
Jianhu’s proprietary TestMaster™ v4.2 software runs natively on the embedded controller and supports offline profile development via Windows PC. The system logs timestamped temperature data at 1 Hz resolution, stores ≥10,000 cycles locally, and exports CSV/Excel-compatible files with embedded metadata (operator ID, chamber ID, calibration date). Audit trail functionality records all parameter modifications, user logins, and emergency stops with immutable timestamps—meeting requirements for GMP Annex 11 and ISO 9001:2015 clause 8.5.2. Remote monitoring is enabled via Ethernet (TCP/IP) with optional Modbus TCP integration into existing MES or SCADA platforms.
Applications
- Qualification testing of solder joints and interconnects in automotive ECUs per AEC-Q200
- Reliability screening of Li-ion battery modules under thermal abuse scenarios (UN 38.3 Section 50.3)
- Validation of hermetic seal integrity in MEMS devices and optoelectronic sensors
- Material compatibility assessment for aerospace composites exposed to stratospheric thermal gradients
- Accelerated life testing of conformal coatings used in military-grade avionics
- Process capability studies for reflow soldering and die-attach curing in semiconductor packaging lines
FAQ
Does the JH-CTC Series comply with international thermal shock standards?
Yes. Each unit is pre-validated against GB/T 2423.22–2012 and IEC 60068-2-14:2016. Full test reports—including temperature mapping, transition time verification, and sensor linearity—are provided with delivery.
Can the chamber be integrated into an existing laboratory LIMS or QMS platform?
Yes. Standard Ethernet interface supports OPC UA and Modbus TCP protocols. Optional API SDK allows custom integration with LabWare, TrackWise, or Veeva systems.
What maintenance intervals are recommended for compressor-based thermal shock chambers?
Compressor oil and filter replacement every 12 months; refrigerant leak check and pressure calibration annually; touchscreen calibration biannually. Preventive maintenance kits and certified field service are available globally.
Is remote diagnostics supported?
Yes. With optional remote access module, Jianhu engineers can perform secure, read-only diagnostics, firmware updates, and configuration review without onsite visits—reducing downtime by up to 70% versus traditional service models.
Are calibration certificates included with shipment?
Yes. NIM-traceable calibration certificates for all Pt100 sensors and chamber uniformity maps are delivered digitally and physically with each unit. On-site IQ/OQ documentation support is available upon request.
