Nordson DAGE Quadra 7 X-ray Radiographic Inspection System

Overview

The Nordson DAGE Quadra 7 is a high-performance, benchtop X-ray radiographic inspection system engineered for precision non-destructive evaluation (NDE) in electronics manufacturing, failure analysis (FA), reliability testing, and quality assurance laboratories. It operates on the principle of transmission X-ray imaging—where a microfocus X-ray source emits photons that penetrate the sample, and differential absorption by internal structures generates contrast captured by a high-resolution flat-panel detector. Designed specifically for advanced packaging technologies—including flip-chip, wafer-level CSP, 3D ICs, SiP, and power modules—the Quadra 7 delivers sub-micron spatial resolution (<0.1 µm at ≤10 W tube power) with exceptional geometric magnification (up to 2,500×) and total system magnification exceeding 68,000×. Its integrated architecture meets the stringent demands of IPC-A-610, J-STD-001, and MIL-STD-883 for solder joint integrity, void detection, wire bond geometry, and interconnect defect identification.

Key Features

• Quadra NT™ microfocus X-ray tube: Closed-tube, transmission-type design with 30–160 kV operating range; achieves 0.1 µm resolution at ≤10 W and 0.3 µm at ≤20 W nominal power
• Aspire FP™ flat-panel detector: 6.7 megapixel sensor with 50 µm pixel pitch, 30 fps real-time frame rate, and 16-bit dynamic range for high-fidelity grayscale rendering
• Dual 24″ 4K UHD displays (3840 × 2160 resolution, 185 PPI): Enable simultaneous multi-view imaging and side-by-side comparative analysis with up to 4× more detail than HD displays
• AxiS™ Active X-ray Image Stabilizer: Real-time motion compensation system mitigates environmental vibration, ensuring consistent image sharpness during long-exposure acquisitions
• Ergonomic manipulator: Motorized XYZ stage with ±70° tilt capability and optional single/dual joystick control for intuitive sample positioning
• Integrated thermal management and dry compressed air (4–6 bar) damping system ensures stable operation across ambient temperatures of 10–30°C and humidity <85% RH (non-condensing)

Sample Compatibility & Compliance

The Quadra 7 accommodates samples up to 29″ × 22.8″ (737 × 579 mm) with maximum weight of 5 kg on standard trays or 500 g on carbon-fiber trays—ideal for PCB assemblies, BGAs, QFNs, power modules, and ceramic substrates. Its 20″ × 17.5″ (508 × 445 mm) field-of-view supports full-board inspection without stitching. The system complies with IEC 61000-6-3 (EMC emissions), IEC 61000-6-2 (immunity), and adheres to radiation safety standards per IEC 62495 and local regulatory requirements for Class II B radiation-emitting devices. Optional CAD overlay functionality enables automated feature registration against Gerber or STEP files for AOI-guided inspection workflows aligned with ISO 10360 and ASTM E2737 metrology validation protocols.

Software & Data Management

Controlled via Windows 10 (64-bit) platform, the Quadra 7 runs DAGE’s proprietary X-Inspect™ software suite—supporting DICOM-compliant image export, audit-trail logging per FDA 21 CFR Part 11 requirements, and GLP/GMP-aligned reporting templates. Advanced digital image processing includes adaptive contrast stretching, edge enhancement, noise suppression, and multi-frame averaging. Optional X-Plane® module provides true 3D volumetric reconstruction (µCT) with isotropic voxel resolution down to 0.5 µm, enabling quantitative porosity analysis, void volume mapping, and cross-sectional slicing per ASTM E1441 and ISO/IEC 17025-accredited methodologies. All image metadata—including kV, µA, exposure time, magnification, detector gain, and calibration timestamps—is embedded and exportable for traceability.

Applications

• Solder joint inspection: Void quantification in QFN, BGA, and LGA packages per IPC-A-610 Class 2/3 criteria
• Wire bond analysis: Lift-off detection, ball shear assessment, and loop profile measurement
• Die attach integrity: Delamination, void distribution, and epoxy spread uniformity evaluation
• PCB layer alignment verification: Inner-layer registration accuracy and via barrel continuity
• Fault isolation in FA labs: Crack propagation tracking, dendrite growth visualization, and moisture-induced corrosion mapping
• Advanced packaging R&D: TSV fill ratio analysis, microbump coplanarity, and hybrid bonding interface characterization

FAQ

What is the minimum detectable feature size under optimal conditions?

Under nominal 10 W tube loading and geometric magnification, the system resolves features down to <0.1 µm—validated using certified line-pair test patterns per ISO 11146-2.
Does the Quadra 7 support automated defect classification?

Yes—when paired with optional AI-driven X-Inspect AI™ add-on, it enables supervised learning-based anomaly detection trained on user-defined defect libraries.
Is µCT reconstruction included as standard?

No—µCT functionality requires the licensed X-Plane® module and additional acquisition time; standard configuration supports only 2D radiography and oblique projection views.
Can the system be integrated into a factory MES or SPC environment?

Yes—via OPC UA and RESTful API interfaces, enabling direct data exchange with Siemens Opcenter, Rockwell FactoryTalk, or custom QA dashboards.
What maintenance intervals are recommended for the X-ray tube?

The Quadra NT™ tube is rated for ≥10,000 hours of operation; annual preventive maintenance (PM) including vacuum integrity check, filament calibration, and detector flat-field correction is advised per Nordson DAGE Service Bulletin SB-Q7-2023-01.
