What Components Can an X-Ray SMD Counter Count? A Concise Guide

2025-11-13

1.Overview

For electronics manufacturers, accurate SMD component counting is critical to avoid inventory discrepancies and production delays. X-ray SMD counters WELLMAN XC-01 offer fast and precise counting solutions, but they are only compatible with specific components. This guide clearly outlines compatible and incompatible parts with supporting visuals for quick reference.


2. Core Counting Conditions

X-ray counters deliver reliable results only when two conditions are met:
  • No component overlap (even partial overlap is not allowed).
  • Components are arranged in a regular, organized pattern.


3. Compatible Components & Packaging

3.1 Standard SMD Reels

The most widely used compatible packaging. Works with all standard reel sizes, no unpacking required (compatible with moisture barrier bags).

Key Specifications:

Size range: 7” (180mm) – 17” (430mm)

  • Accuracy: ≥99.98% (for 01005 components), ≥99.99% (for 0201 and above)
  • Speed: 4×7” reels counted in 7–10 seconds

3.2 Single-Layer Trays

Neatly arranged single-layer components (e.g., ICs, resistors) are ideal. The grid structure enables easy AI recognition.

3.3 Tube-Packaged Components

Uniformly arranged delicate parts (diodes, small transistors) in tubes. X-rays penetrate the packaging without damaging components.

4. Uncountable Components

Components that violate the "no overlap + regular arrangement" rule cannot be counted accurately.

Main Scenarios:

  1. Overlapped/stacked components
  2. Loose parts in bags or tangled reels
  3. Thick metal casings blocking X-rays


5. WELLMAN XC-01 Advantages

  • AI deep learning: No pre-programming required
  • Cloud algorithm updates: Expands component compatibility continuously
  • Safety compliance: ≤1μSv/h radiation, anti-pinch design
  • System integration: Connects to MES/ERP/WMS systems seamlessly
