Jianhu JH-ETC Series High-Low Temperature Environmental Test Chamber for Battery & Semiconductor Testing

Overview

The Jianhu JH-ETC Series High-Low Temperature Environmental Test Chamber is an engineered solution for accelerated environmental stress testing of electrochemical cells, power batteries, and semiconductor devices under controlled thermal conditions. Designed in accordance with IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and MIL-STD-810G thermal cycling protocols, the chamber employs dual-stage compressor refrigeration coupled with PID-controlled resistive heating to deliver stable, repeatable thermal profiles across a wide operational range (–70 °C to +150 °C). Its explosion-proof configuration complies with Class I, Division 1, Group C/D hazardous location requirements per UL 60079-0 and GB/T 3836.1–2021, making it suitable for testing lithium-ion, solid-state, and sodium-ion battery cells during safety qualification (e.g., UN 38.3 T1–T5), as well as for burn-in and parametric validation of ICs, MEMS sensors, and optoelectronic packages.

Key Features

• Robust thermal architecture featuring hermetic scroll compressors, copper-aluminum finned evaporators, and high-efficiency axial fans for rapid, uniform air circulation
• Explosion-proof enclosure rated IP65 with intrinsically safe internal wiring, reinforced stainless-steel interior, and flame-retardant insulation materials
• High-precision temperature control system with Pt100 Class A sensors (±0.15 °C accuracy) and adaptive PID algorithm ensuring ±0.5 °C fluctuation and ±2.0 °C uniformity across working volume
• Programmable ramp-soak profiles supporting up to 99 segments, 999 cycles, and user-defined dwell times — compatible with ASTM D3418 and ISO 11357 thermal analysis workflows
• Double-wall vacuum-insulated construction with low-conductivity polyurethane foam (λ ≤ 0.022 W/m·K) minimizing energy consumption and external surface temperature rise
• Modular chamber sizing: standard internal dimensions include 300 × 400 × 400 mm (L×W×H), 500 × 600 × 600 mm, and 800 × 1000 × 1000 mm — all configurable with optional humidity control integration

Sample Compatibility & Compliance

The JH-ETC chamber accommodates battery modules (up to 200 kg load capacity), wafer trays (200 mm/300 mm), PCB assemblies, and packaged semiconductor devices (QFN, BGA, CSP). Internal chamber geometry supports standardized test fixtures per JEDEC JESD22-A104 (temperature cycling) and JESD22-A106 (highly accelerated temperature-humidity stress test). All units undergo factory calibration traceable to NIM (National Institute of Metrology, China) and are supplied with a Certificate of Conformance per ISO/IEC 17025:2017. The system meets CE marking requirements (EMC Directive 2014/30/EU, LVD Directive 2014/35/EU), RoHS 2011/65/EU, and is designed for GLP-compliant lab environments with optional audit trail logging.

Software & Data Management

Equipped with Jianhu’s proprietary ETC-Link™ control software (Windows-based, English UI), the chamber supports real-time monitoring of chamber temperature, compressor status, alarm history, and cycle progress via USB or Ethernet interface. Data export is available in CSV and Excel formats; time-stamped logs include sensor readings at user-configurable intervals (1 s to 60 min). Optional FDA 21 CFR Part 11 compliance package includes electronic signatures, role-based access control, and immutable audit trails for regulated battery safety labs and semiconductor QA departments. Remote supervision via Modbus TCP or OPC UA is supported for integration into MES or SCADA platforms.

Applications

• Battery safety testing: thermal runaway propagation studies, storage stability assessment at extreme temperatures, and charge/discharge performance mapping under thermal stress
• Semiconductor reliability: high-temperature operating life (HTOL), early-life failure screening (ELF), and temperature cycling qualification per AEC-Q200 and JEDEC standards
• Material characterization: coefficient of thermal expansion (CTE) evaluation of packaging substrates, solder joint fatigue modeling, and die attach integrity verification
• R&D validation: environmental screening of EV traction battery packs, aerospace-grade power electronics, and medical-grade implantable battery systems
• Quality assurance: incoming inspection of wafer-level chips, final acceptance testing of automotive ECUs, and shelf-life validation of solid-state battery prototypes

FAQ

What standards does the JH-ETC chamber comply with for battery testing?
It supports test execution per UN 38.3, IEC 62133-2, IEEE 1625/1725, and GB/T 31485–2015 — with documented thermal profile repeatability verified against NIST-traceable reference thermometers.
Is remote firmware update supported?
Yes — firmware upgrades are delivered via secure HTTPS endpoint and require administrator authentication; version history and changelogs are retained in system memory.
Can the chamber be integrated into an existing lab automation network?
Absolutely — native support for Modbus RTU/TCP, Ethernet/IP, and optional Profibus-DP gateways enables seamless connection to PLCs, LIMS, and central monitoring systems.
What is the typical lead time for custom chamber configurations?
Standard models ship within 15 business days; large-volume or explosion-proof variants with extended temperature ranges require 6–8 weeks from order confirmation.
Does Jianhu provide IQ/OQ documentation for GMP environments?
Yes — validated installation qualification (IQ) and operational qualification (OQ) protocols are available upon request, aligned with ASTM E2500 and Annex 15 guidelines.
