Overview
The Zhengye ZY-BI-2000 Series is a high-resolution, fully automated X-ray inspection system engineered specifically for non-destructive evaluation of semiconductor die attach and wire bonding integrity. Utilizing microfocus X-ray imaging (≤5 µm focal spot size) combined with real-time digital radiography (DR) and advanced edge-enhanced reconstruction algorithms, the system enables sub-micron-level visualization of bond geometry, interfacial voids, solder wetting quality, and wire loop profile anomalies. Unlike generic industrial X-ray platforms, the ZY-BI-2000 integrates purpose-built mechanical handling, thermal-stable sample positioning, and application-specific calibration protocols aligned with JEDEC J-STD-020, IPC-A-610, and AEC-Q200 requirements. It is designed for inline or offline deployment in wafer-level packaging (WLP), flip-chip, and discrete power device manufacturing environments where reliability validation must meet automotive-grade AEC-Q100 stress test qualification thresholds.
Key Features
- Microfocus X-ray source (≤5 µm spot size) with dual kV range (30–130 kV) optimized for silicon, copper, gold, and aluminum interconnect contrast differentiation
- High-dynamic-range flat-panel detector (≥16-bit depth, 100 µm pixel pitch) enabling simultaneous capture of thick substrate layers and fine wire bonds
- Automated stage with ±0.5 µm repeatability and programmable tilt/rotation for multi-angle oblique projection imaging
- Embedded AI-powered defect classification engine trained on >50,000 annotated bond images from production lots across SiC MOSFETs, IGBT modules, and GaN HEMTs
- Real-time anomaly scoring with configurable pass/fail thresholds per defect class (e.g., neck thickness deviation >12%, loop height variance >8%)
- Modular software architecture supporting integration into factory MES via SECS/GEM and OPC UA interfaces
Sample Compatibility & Compliance
The ZY-BI-2000 accommodates substrates up to 300 mm × 300 mm and component heights up to 50 mm, supporting bare dies, leadframes, ceramic DBC substrates, and molded packages (QFN, TO-247, D2PAK). All image acquisition and analysis workflows comply with ISO/IEC 17025 traceability requirements for measurement uncertainty reporting. The system’s defect taxonomy aligns with IPC-7095B (Design and Assembly Process Implementation for BGAs) and JEDEC JESD22-A111 (Wire Bond Pull Test Standard), while audit logs and electronic signatures satisfy FDA 21 CFR Part 11 and EU Annex 11 data integrity mandates for GMP-regulated facilities.
Software & Data Management
The proprietary Zhengye VisionInsight™ v4.2 software provides full GLP-compliant workflow control: user role-based access (admin/operator/auditor), versioned algorithm libraries, and immutable audit trails recording every image acquisition parameter, threshold adjustment, and classification decision. Raw DICOM-RT datasets are archived with embedded metadata (lot ID, timestamp, operator ID, machine calibration ID). Statistical process control (SPC) dashboards generate Cp/Cpk metrics per defect type and track trend shifts using Western Electric rules. Export formats include CSV (for JMP/Minitab), XML (for SPC systems), and PDF reports compliant with ISO 9001 clause 8.2.4.
Applications
- Quantitative assessment of solder joint voiding (%) in flip-chip underfill processes
- Detection and geometric quantification of wire bond lift-off, neck cracking, and ball shear anomalies in Au/Al wedge bonding
- Measurement of bond pad coverage ratio and intermetallic compound (IMC) layer uniformity in Cu wire bonding
- Statistical correlation of X-ray-derived bond morphology parameters with thermal cycling failure modes (JEDEC JESD22-A104)
- Root cause analysis support for yield loss investigations in high-power module assembly lines
FAQ
Does the system support real-time inline integration with pick-and-place or die bonder equipment?
Yes — optional SECS/GEM interface enables bidirectional communication with major OEM handlers (ASM Pacific, Besi, Mycronic) for automated lot-triggered inspection and closed-loop feedback to placement offset correction.
What level of training and certification is required for operators?
A two-day certified operator program covers image physics fundamentals, defect signature interpretation, SPC chart reading, and audit trail review; certification is renewed annually per internal QA policy.
Is remote diagnostics and algorithm update capability available?
All units ship with TLS-secured remote access enabled; Zhengye engineers may perform diagnostic sessions and deploy validated algorithm updates (with version-controlled changelogs and impact assessments) without onsite intervention.
How is measurement uncertainty characterized for critical dimensions like neck thickness or ball diameter?
Uncertainty budgets follow GUM (JCGM 100:2008) methodology, incorporating contributions from geometric magnification error, detector MTF, beam hardening, and reference standard traceability to NIST SRM 2036 (micro-feature calibration artifact).
