Product Description
XR90-L9421-02 (Hamamatsu L9421-02) Microfocus X-ray Source
Product Introduction

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.

We supply fully inspected replacement X-ray tubes. Besides sales of individual spare parts, we provide equipment upgrade & retrofitting services and long-term whole-line supporting cooperation for X-ray equipment OEMs and large EMS factories, accompanied with remote technical support for installation and calibration.

Product Features & Cooperation Solutions
Core Product Features
  • 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.
Whole-line Supporting & Cooperation Solutions
  • 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.
Frequently Asked Questions
What is the difference between XR90-L9421-02 and L9421-02?
They refer to the same product. XR90-L9421-02 is the widely used part number in the SMT spare parts market, and L9421-02 is the original Hamamatsu model with identical technical specifications.
What X-ray inspection equipment is it compatible with?
Compatible with most desktop SMT X-ray testers and micro CT devices originally equipped with L9421-02 tube core. Please provide your equipment brand and model so we can verify compatibility.
What inspections will be carried out before delivery?
Every unit will pass power-on test, tube voltage/current stability test, focal spot verification and imaging quality inspection before shipment.
What cooperation options are available for X-ray OEM manufacturers?
Trial orders are supported prior to mass supply. Annual supply framework agreements and inventory reservation are available; exclusive bulk discounts can be offered for whole-line projects.
Will calibration service be provided after replacing the X-ray source?
Remote guidance for installation, commissioning and calibration is available. On-site service can be negotiated separately based on the project location.
What is the MOQ and lead time?
MOQ is 1 piece. Quick shipment for stocked items. Exact lead time depends on the delivery address and logistics method.
What is the warranty policy?
Warranty terms are specified on the proforma invoice. Damage caused by improper installation or overvoltage operation is not covered under warranty.
