Product Details
Overview
The HAST Chamber (Highly Accelerated Stress Test Chamber) PC series, including models like PC-3048, PC-422R9, PC-304R9, and PC-422R9D, is engineered for accelerated aging tests of electronic parts, such as semiconductors and PCBs. It utilizes a unique dual-chamber structure that separates the test chamber from the steam generator, minimizing condensation risks and maximizing usable space. With an operational range of up to 500 hours continuously, it ensures high precision under conditions like 100% RH, making it ideal for rigorous industrial reliability assessments. The device is manufactured by Hirayama, holding relevant pressure vessel certifications for safety.
Core Technological Features
1. Dual-Chamber Design
The PC series stands out with its Dual Chamber architecture, where the test chamber (dry bulb) and steam generator (wet bulb) operate independently. This design leverages pressure differences to facilitate natural convection of steam, ensuring uniform humidity distribution and preventing condensation during temperature ramps. Compared to single-chamber alternatives, it expands effective test volume (e.g., 84.4 L for PC-422R9) and eliminates common wear parts like fans or wicks, reducing contamination risks.
The dual-chamber approach avoids issues such as metal powder from fans, which can pollute the chamber in single-chamber systems.
This structure aligns with IEC 68-2-66 standards, providing larger usable space and wider humidity control.
2. Intelligent Control System
Equipped with a high-precision temperature-humidity program controller, the PC series supports programmable operations with up to 150 patterns and 150 steps. The LCD touchscreen allows easy setup, while remote control via PCs, smartphones, or tablets enables centralized management of up to 16 units. Two test modes are available: HUM (unsaturated mode, 65–100% RH adjustable) for dew-condensation prevention and STD (saturated mode, 100% RH) for traditional pressure cooker tests. Real-time trend graphs display progress, and data can be saved to external USB drives for record-keeping.
The controller includes self-diagnostic functions and preheating options to streamline testing.
3. Safety and Usability Enhancements
Drawer-Style Door Operation: A sliding tray mechanism allows the sample tray to fully extend outside the chamber, enabling easy loading and unloading without hand insertion into hot environments. This electric clamp system opens in about 8 seconds, enhancing operator safety.
Comprehensive Safety Protections: The chamber includes multiple safeguards, such as pressure safety valves, over-temperature cutoffs, leakage breakers, and door lock checks. It holds a Chinese pressure vessel manufacturing license (No. TS2200945-2022) and safety valve certification (A1 level), ensuring compliance with international safety standards.
Voltage Terminal Flexibility: Standard 20 terminals (125V) can be expanded to 60–100 terminals, supporting high-voltage (1000V) and extra-high-voltage (3000V) customizations. Four reserved holes allow for future upgrades, reducing project costs.
4. Key Performance Specifications
For model PC-422R9, external dimensions are W900 × D1100 × H1780 mm, with a test chamber size of Φ420 × D657 mm (84.4 L). Temperature control accuracy is ±0.5°C, humidity accuracy ±3% RH (at 85% RH), and pressure range 0.019–0.208 MPa. Three exhaust modes cater to different sample needs: slow cooling with humidity maintained, cooling with moisture kept, and quick exhaust. The chamber is made of electropolished SUS316L stainless steel for easy cleaning and stain resistance. Power supply options include 1φ AC220–240V, with heater capacities tailored for efficient steam generation.
5. Certifications and Compatibility
The series meets IEC 60068-2-66 requirements and offers optional features like air HAST mode and residual air control. Communication interfaces (RS-485/232C) enable integration with network systems, while dedicated software simplifies program editing. Preheating functions allow fixed-value operations without complex programming, and the cooling tank ensures safe drainage.
Dual overpressure protection and door safety systems further enhance reliability.
Applications
The PC series is widely used in semiconductor aging tests, PCB reliability verification, and accelerated life testing of electronic components. Its dual-chamber design is particularly suited for humidity-sensitive materials, while multi-channel voltage terminals support parallel bias testing, improving R&D efficiency in industries like automotive electronics and consumer devices.
