LabCompanion HH-Series High Temperature Aging Test Chamber

Overview

The LabCompanion HH-Series High Temperature Aging Test Chamber is an engineered environmental test system designed for controlled thermal stress evaluation of materials, electronic components, polymers, coatings, and packaging under sustained elevated temperatures. It operates on the principle of forced-air convection, where a high-efficiency, low-noise axial fan circulates heated air uniformly across the test chamber interior—ensuring consistent thermal exposure and minimizing spatial gradients. Unlike passive oven designs, this chamber integrates a closed-loop airflow architecture with adjustable baffle plates to optimize heat distribution and improve thermal uniformity across the full working volume. Its operational range extends from ambient +10°C up to 250°C, making it suitable for accelerated aging protocols defined in industry standards such as IPC-TM-650, ASTM D3045 (thermal aging of plastics), and IEC 60068-2-2 (dry heat testing). The chamber’s robust construction—including argon-welded mirror-finish SUS304 stainless steel interior and powder-coated SECC steel exterior—ensures long-term dimensional stability, corrosion resistance, and compliance with laboratory-grade durability expectations.

Key Features

• Microprocessor-based digital temperature controller with intuitive LED interface and programmable timer (1–9999 minutes)
• High-reproducibility thermal control: ±0.5°C temperature uniformity across the entire chamber volume at steady state
• Forced-air circulation system utilizing a high-temperature-rated axial fan capable of continuous operation at 250°C
• RS485 serial interface enabling real-time temperature monitoring, remote parameter adjustment, and integration with external data loggers or SCADA systems
• Two removable, load-rated stainless steel shelves with reinforced support structure for flexible sample arrangement
• Energy-efficient design achieving up to 45% thermal efficiency—significantly higher than conventional radiant ovens—through optimized duct geometry and minimized heat leakage
• Thermal insulation using high-density mineral fiber board (≥100 mm thickness) to maintain external surface temperature below 45°C during operation at maximum setpoint

Sample Compatibility & Compliance

The HH-Series accommodates a broad spectrum of non-volatile, non-explosive test specimens—including PCB assemblies, solder paste samples, elastomers, adhesives, thin-film substrates, and encapsulated semiconductor devices. Its internal chamber dimensions (450 × 550 × 550 mm) support standard IPC-compliant test boards and multi-layer sample racks. The chamber meets structural and functional criteria outlined in IPC-TM-650 Section 2.6.22 (Thermal Aging), and its thermal performance aligns with the repeatability and stability requirements of ISO/IEC 17025-accredited laboratories. While not intrinsically explosion-proof, it complies with general electrical safety standards IEC 61010-1 for laboratory equipment and incorporates over-temperature cut-off protection per UL 61010-1. Optional calibration certificates traceable to NIST standards are available upon request for GLP/GMP-regulated environments.

Software & Data Management

The built-in RS485 interface supports Modbus RTU protocol for seamless integration into existing laboratory informatics infrastructure. When connected to a host PC running compliant data acquisition software (e.g., LabVIEW, WinCC, or custom Python-based scripts), users can perform real-time temperature trending, generate audit-ready CSV logs, and implement automated pass/fail validation against pre-defined thermal profiles. The controller retains timestamped event history—including power interruptions, setpoint changes, and alarm triggers—for full traceability. For regulated applications requiring electronic record integrity, optional firmware upgrades enable 21 CFR Part 11-compliant user authentication, electronic signatures, and immutable audit trails—supporting FDA-submission readiness in pharmaceutical or medical device development workflows.

Applications

• Accelerated thermal aging of printed circuit boards (PCBs) and conformal coatings per IPC-TM-650 2.6.22
• Evaluation of long-term thermal stability in polymer films, gaskets, and sealing compounds
• Pre-conditioning of sensors, batteries, and optoelectronic modules prior to functional testing
• Material compatibility screening for high-temperature packaging and sterilization processes
• Qualification of solder mask and underfill materials under extended thermal soak conditions
• Supporting failure analysis (FA) labs in replicating field-induced thermal degradation mechanisms

FAQ
