Vacuum Leak Detection Equipment
Advanced Vacuum Leak Detection
Vacuum integrity is the cornerstone of high-performance system engineering, where the margin between operational success and catastrophic failure is measured in atomic-scale gas permeation. AIMRSE specializes in high-fidelity leak detection architectures that integrate advanced mass spectrometry and quantitative pressure analysis to identify micro-breaches within complex hermetic structures. Our methodologies transcend basic boundary testing, focusing on the fundamental physics of gas kinetics and molecular flow to ensure absolute system isolation. By leveraging state-of-the-art helium tracer gas technology and differential pressure sensing, our equipment provides a detection threshold reaching $10^{-13}$ Pa·m³/s. These systems are engineered for seamless integration into semiconductor fabrication lines, aerospace simulation chambers, and New Energy battery assembly cycles, where mitigating the risks of outgassing and atmospheric contamination is non-negotiable for long-term reliability.

Helium Mass Spectrometer Leak Detectors
AIMRSE's helium mass spectrometry systems represent the pinnacle of quantitative gas analysis. Engineered with high-stability ion sources and advanced signal processing algorithms, these units deliver industry-leading response times and background suppression. Available in both "dry" (oil-free) configurations for cleanroom environments and high-throughput "wet" variants for industrial testing, our detectors feature modular maintenance interfaces and intelligent auto-calibration. With a dynamic range spanning 12 decades, they are essential for validating the hermeticity of semiconductor components, cryogenic vessels, and particle accelerators.

Industrial Applications & Technical Benchmarks
UHP Gas Delivery System Integrity Validation
For a leading 300mm wafer fabrication plant, AIMRSE deployed a high-sensitivity helium leak detection protocol to validate Ultra-High Purity (UHP) gas delivery manifolds. Ensuring zero atmospheric back-diffusion is critical to prevent dopant contamination and maintain gate oxide quality in sub-7nm process nodes.
Technical Challenges & Engineering Solutions:- Background Noise: Utilized split-flow turbo-molecular pumping to maintain stable helium background in a high-traffic fab.
- Conductance Optimization: Engineered custom CF-flanged manifolds to maximize helium conductance and minimize response lag.
- Sensitivity: Achieved verified leak rate thresholds of $< 10^{-11}$ mbar·l/s for entire valve manifold assemblies.
Large-Scale Thermal Vacuum Chamber (TVC) Testing
AIMRSE provided the vacuum integrity assessment for a 10-meter diameter satellite simulation chamber. The project required detecting micro-leaks in cryogenic shroud welds and feedthrough interfaces that could compromise the $10^{-7}$ Pa base pressure required for orbital simulation.
Technical Challenges & Engineering Solutions:- Volume Scale: Implemented a multi-point helium tracer gas injection system to map large-scale volumetric breaches.
- Cryogenic Sealing: Developed specialized low-temperature gaskets to maintain hermeticity at 77K during thermal cycling.
- Real-time Monitoring: Integrated the leak detector with the facility's SCADA for continuous vacuum health monitoring.
Automated Prismatic Cell Leak Detection Line
Designed for a Tier-1 EV battery manufacturer, this automated station performs high-speed helium leak testing on prismatic lithium-ion cells post-sealing. This ensures long-term electrolyte stability and prevents moisture ingress over the battery's 10-year lifespan.
Technical Challenges & Engineering Solutions:- Cycle Time: Optimized vacuum chamber evacuation and vent cycles to achieve a Takt time of < 6 seconds per cell.
- Automated Tooling: High-precision pneumatic grippers with integrated sealing caps for localized testing.
- Data Integration: Direct handshake with the MES for individual cell pass/fail serial number tracking.
UHV Beamline Vacuum System Integration
Collaborating with a national synchrotron facility, AIMRSE engineered the leak detection strategy for a new soft X-ray beamline. The system operates at Extremely High Vacuum (XHV) levels, where even a single molecular leak would induce carbon contamination on delicate X-ray optics.
Technical Challenges & Engineering Solutions:- Outgassing Control: All testing tooling was UHV-cleaned and baked to $200^\circ$C to eliminate surface water vapor.
- Resolution: Utilized a customized mass spectrometer with high resolution to distinguish helium from deuterium background.
- Reliability: System verified for 24/7 operation in radiation-shielded environments.
Customer Reviews
"Implementing AIMRSE's helium mass spectrometer leak detector into our semiconductor valve production line was a transformative decision. The most critical advantage was the system's rapid recovery time after high helium exposure; unlike previous detectors that suffered from prolonged background saturation, the AIMRSE unit suppressed the helium signal within seconds. This significantly reduced our cycle times for UHP manifold validation. The integrated calibration standard is NIST traceable, which simplified our compliance audits for Tier-1 wafer fab customers. Their technical team's understanding of vacuum conductance was evident in the custom manifold they engineered for our test fixtures."
