LabCompanion YC-021-65-L Two-Zone Basket-Transfer Thermal Shock Test Chamber

Overview

The LabCompanion YC-021-65-L is a two-zone basket-transfer thermal shock test chamber engineered for precise, repeatable evaluation of electrical and electronic components under rapid, extreme temperature transitions. It operates on the principle of mechanical thermal shock—utilizing separate high-temperature (+150 °C) and low-temperature (−40 °C) storage chambers with a pneumatically actuated stainless-steel transfer basket that moves specimens between zones in ≤10 seconds. This architecture eliminates transitional thermal inertia associated with single-chamber ramping, enabling true step-change thermal stress per IEC 60068-2-14 and MIL-STD-810G methods. Designed specifically for compliance testing of electrical products per GB/T 2423 series and GJB 150A standards, the chamber delivers high reproducibility in temperature deviation (±2.0 °C), uniformity (≤2.0 °C), and recovery stability (≤5 min), making it suitable for qualification, reliability screening, and failure mode analysis in QC/QA and R&D laboratories.

Key Features

• Independent dual-zone design with insulated hot/cold reservoirs and rapid basket transfer mechanism for true thermal shock without thermal lag
• Energy-optimized control architecture: eliminates traditional “cold–hot balance” heating/cooling overlap; achieves >30% power reduction via dynamic refrigerant output modulation and SSR-controlled heating
• High-stability PID + fuzzy logic temperature control with 0.6-second sampling cycle (0.3 s for temperature), real-time deviation display, and auto-compensated overshoot suppression
• Robust thermal insulation: 100 mm composite layer comprising high-density polyurethane foam and ultra-fine glass fiber; external cabinet in powder-coated steel, internal chamber in SUS304 stainless steel
• Uniform airflow system with multi-blade centrifugal fans, optimized wind duct layout, and non-direct top-down air discharge to prevent localized thermal loading on test samples
• Integrated safety architecture: triple-tier over-temperature protection (programmable, electronic, and mechanical), compressor safeguards (high-pressure, overheat, overcurrent), phase-loss and leakage protection, and active water-level monitoring for humidity-capable variants

Sample Compatibility & Compliance

The YC-021-65-L is intended exclusively for non-hazardous, non-volatile, non-corrosive, and non-biological electrical/electronic assemblies. Per IEC 60068-1 and GB/T 5170.1–2008, prohibited sample categories include flammable, explosive, radioactive, highly toxic, or strongly electromagnetic-emitting devices. Load configuration must adhere to strict spatial and mass constraints: maximum 10 kg total load (≤10% of chamber volume), solid aluminum dummy loads occupying no more than 20% of internal volume, and frontal cross-sectional blockage limited to ≤33% of air inlet area. All operational parameters—including temperature fluctuation, recovery time, and uniformity—are verified under empty-chamber conditions per ISO/IEC 17025-accredited calibration protocols. The chamber meets full traceability requirements for GLP/GMP environments, supporting FDA 21 CFR Part 11–compliant audit trails when paired with optional networked data logging.

Software & Data Management

The C100-series 7-inch capacitive touchscreen controller provides full programmability with ≥100 stored profiles, each supporting up to 100 steps and 32,000 cycles. Users may define variable ramp rates, dwell times, loop nesting, and conditional branching. Real-time temperature curves are rendered with timestamped PV/SV overlay, deviation calculation, and point-click interrogation. Historical data is archived at user-selectable intervals (1–60 s); default 30-second logging enables 600 days of continuous storage. Data export is supported via USB 2.0 (CSV/PDF), RS-485 serial interface, or Ethernet (RJ45) using Modbus RTU/TCP protocol. Optional PC-based software enables remote monitoring, automated report generation (PDF/Excel), and integration into LIMS or MES platforms. All system events—including alarms, setpoint changes, and manual interventions—are logged with timestamps and operator IDs, satisfying GLP audit requirements.

Applications

This thermal shock chamber serves critical functions across electronics manufacturing and certification workflows: solder joint integrity validation per IPC-A-610; PCB interconnect fatigue assessment under repeated thermal cycling; qualification of automotive ECUs per AEC-Q200; accelerated life testing of power semiconductors and battery management systems; verification of encapsulant adhesion and CTE mismatch in hybrid modules; and environmental stress screening (ESS) of avionics hardware prior to HALT/HASS. Its adherence to GB/T 2423.22–2012 (temperature change) and GJB 150.5A–2009 ensures direct applicability in Chinese military and industrial certification submissions. Laboratories performing third-party conformity assessments for CCC, CE, or UL listings rely on its metrologically validated performance envelope.

FAQ

What is the minimum required ambient condition for stable operation?

Ambient temperature must be maintained between 5 °C and 35 °C, relative humidity ≤85% RH, and atmospheric pressure 86–106 kPa. Adequate ventilation and floor load capacity ≥500 kg/m² are mandatory.

Can this chamber perform humidity-controlled thermal shock tests?

No—the YC-021-65-L is a dry thermal shock system. Humidity capability requires a separate model with integrated steam humidification and condensate management.

Is the controller compliant with FDA 21 CFR Part 11 for electronic records?

Yes—when configured with password-protected user roles, electronic signatures, and immutable audit logs, the C100 controller meets core Part 11 requirements for record retention and system validation.

What maintenance intervals are recommended for long-term reliability?

Compressor oil and refrigerant levels should be verified annually; evaporator and condenser coils cleaned quarterly; door gaskets inspected monthly; and temperature sensors calibrated every six months per ISO/IEC 17025 procedures.

Does the chamber support custom test profiles beyond standard GB/T or GJB methods?

Yes—users may define arbitrary temperature sequences, dwell durations, transition rates, and conditional triggers via the graphical programming interface, enabling proprietary stress protocols and failure acceleration models.
