The XR90-L9421-02 (Hamamatsu L9421-02) sealed microfocus X-ray source is a core critical component for SMT X-ray inspection equipment and 3D micro CT electronic non-destructive testing.

This 90kV X-ray tube delivers high-definition imaging to accurately detect internal defects such as BGA voids, solder joint failures, and IC package delamination. Adopting a fully sealed structure, it eliminates regular vacuum maintenance and supports long-hour stable continuous operation of SMT production lines.

• 5μm ultra-fine focal spot at 4W power: Clearly captures tiny BGA voids and subtle solder defects, suitable for inspection of high-density PCBs and advanced semiconductor packages.
• Adjustable voltage & current (20-90kV / 0-200μA): Flexible parameters to meet diversified inspection requirements for different substrates and IC packages.
• Fully sealed integrated tube body: No vacuum refilling required, low maintenance cost, effectively reducing downtime loss on SMT production lines.
• RS-232C standard communication interface: Easily integrated into new or existing X-ray inspection systems with simple commissioning.
• Compact structure: Ideal for retrofitting old X-ray equipment, as well as building new desktop or inline inspection stations.

• Individual spare part supply: In stock, fully tested before shipment. Available for emergency replacement of faulty equipment to quickly resume production.
• Equipment retrofitting & upgrade: Replace aging X-ray tubes and recalibrate the imaging system. It greatly cuts investment costs compared with purchasing brand-new equipment.
• OEM Bulk & Whole-line Project Cooperation: Stable long-term spare parts supply. Trial orders available before mass procurement with reserved inventory. Tiered volume discounts for large whole-line projects.
• Technical supporting service: Remote guidance for installation, wiring and basic parameter calibration to assist customers with system integration.
