JianHu JH-Series Rapid Thermal Cycling Chamber (Cold/Hot Shock Test System)

Overview

The JianHu JH-Series Rapid Thermal Cycling Chamber is an engineered environmental test system designed for accelerated thermal shock testing in accordance with international reliability standards including MIL-STD-810H, IEC 60068-2-14, and ASTM D5229/D5229M. It implements a dual-chamber or single-chamber (mechanical air-shuttle) architecture—configurable per application—to subject test specimens to rapid, repeatable transitions between extreme high- and low-temperature zones. The system operates on the principle of controlled convective heat transfer, utilizing high-efficiency hermetic compressors, optimized refrigerant circuits (R404A/R23 cascade or R134a single-stage), and PID-regulated resistive heating elements. Its core function is to induce thermally induced mechanical stress in materials and assemblies—such as solder joints, encapsulants, laminates, and hermetic seals—thereby revealing latent defects like microcracking, delamination, or interfacial fatigue that may not manifest under static temperature exposure.

Key Features

• Programmable thermal shock profiles: Supports multi-step cycles with independent control of high-temperature (up to +150 °C), low-temperature (down to −70 °C), dwell time, transition time, and cycle count
• Rapid transition capability: Achieves ≤15-second transfer time between chambers (dual-zone configuration) or ≤30-second ramp rates of ≥10 °C/min (air-shuttle configuration), verified per IEC 60068-2-14 Annex A
• High uniformity & stability: ±0.5 °C temperature uniformity across working volume; ±0.3 °C steady-state stability at setpoint
• Intelligent control architecture: Equipped with a 10.4-inch color touchscreen HMI running embedded real-time OS, supporting RS485/Modbus RTU, Ethernet TCP/IP, and optional USB data logging
• Robust chamber construction: 304 stainless steel inner chamber, polyurethane foam insulation (≥150 mm thickness), double-glazed observation window with anti-fog heater, and over-temperature/over-pressure safety interlocks
• OEM/ODM flexibility: Customizable internal dimensions (from 50 L to 1000 L), extended temperature ranges (e.g., −80 °C to +200 °C), specialized sample fixtures, and integration-ready I/O for factory automation (PLC handshake, alarm relay outputs)

Sample Compatibility & Compliance

The JH-Series accommodates a broad range of specimen types—including PCBAs, automotive ECUs, MEMS sensors, aerospace composites, medical device housings, and polymer-based packaging—without requiring modification to part geometry or mounting methodology. Standard chamber configurations support standard test trays (ISO 2041, DIN 50017) and accommodate fixtures compliant with JEDEC JESD22-A104 and IPC-9701. All units are manufactured under ISO 9001:2015–certified quality management systems and undergo full FAT (Factory Acceptance Testing) per IEC 61000-4-2/4-3 EMC requirements. Documentation packages include calibration certificates traceable to NIM (National Institute of Metrology, China), CE marking documentation (per 2014/30/EU and 2014/35/EU), and optional IQ/OQ validation protocols aligned with GLP and GMP environments.

Software & Data Management

The embedded control software provides full cycle definition, real-time graphing of chamber temperatures (high-zone, low-zone, payload), event-triggered alarms (e.g., door open, compressor fault, sensor drift >±1 °C), and automatic report generation in PDF/CSV format. Optional PC-based JianHuTest Suite v3.2 enables remote monitoring via LAN/WAN, multi-chamber fleet management, audit trail logging compliant with FDA 21 CFR Part 11 (electronic signatures, user access levels, change history), and export to LIMS-compatible formats (ASTM E1382, ISO/IEC 17025). All firmware updates are delivered via secure HTTPS download with SHA-256 signature verification.

Applications

• Electronics reliability: Qualification of flip-chip BGA packages, wafer-level CSPs, and power modules per AEC-Q200 and JEDEC J-STD-020
• Automotive component validation: Testing of ADAS cameras, battery management systems (BMS), and engine control units under combined thermal shock and vibration per ISO 16750-4
• Aerospace hardware screening: Pre-flight qualification of avionics enclosures, optical benches, and thermal control coatings per ECSS-Q-ST-70-08C
• Material science research: Accelerated aging studies of thermoset resins, shape-memory alloys, and phase-change materials under cyclic ΔT gradients
• Medical device development: Verification of sterilization-resistant housing integrity and sensor drift behavior in implantable pulse generators

FAQ

What temperature ranges are available for the JH-Series?
Standard configurations cover −70 °C to +150 °C; extended-range variants support −80 °C to +200 °C upon request.
Can the system be integrated into an automated test line?
Yes—standard dry-contact I/O, Modbus TCP, and optional OPC UA enable seamless integration with MES and SCADA platforms.
Is third-party calibration and certification supported?
All units ship with NIM-traceable calibration reports; we provide on-site IQ/OQ services and support external accreditation by TÜV SÜD, SGS, or UL upon customer request.
What is the typical lead time for custom configurations?
Standard models ship within 4–6 weeks; fully customized systems (e.g., non-standard chamber geometry, special cooling media, or Class 100 cleanroom compliance) require 10–14 weeks from PO confirmation.
Does JianHu provide technical training and after-sales support?
Yes—comprehensive on-site commissioning, operator training, and preventive maintenance programs are included; global service network covers APAC, EMEA, and North America via authorized partners.
