JD-FAI955 SMT First Article Detector: Fast, Full-Coverage FAI Solution for SMT Production Lines

In SMT (Surface-Mount Technology) manufacturing, first article inspection (FAI) is a critical quality gate before batch production. Yet traditional manual FAI has long plagued SMT workshops: lengthy inspection cycles, high labor costs, incomplete test coverage, frequent human errors, and limited traceability when issues arise.
As a professional SMT inspection equipment manufacturer based in Shenzhen, Subit presents the JD-FAI955 intelligent FAI terminal — purpose-built to solve these exact pain points.
Full-Coverage Inspection Capabilities
The JD-FAI955 works with all common SMT pre-reflow board types:
- Solder paste boards (for components placed after solder paste printing)
- Pertinax / double-sided adhesive boards
- Red rubber boards (for components placed after red adhesive printing)
It delivers comprehensive defect detection across three dimensions:
1. **Document & data errors**: Incorrect BOM consumption, duplicate positions, missing or redundant XY coordinate definitions
2. **Assembly & placement defects**: Extra paste, missing components, wrong parts, reversed polarity, component rollover, PCB offset or rotation
3. **Electrical performance validation**: Resistance, capacitance and inductance value testing; diode polarity verification and LED functional testing to catch incoming material defects
Core LCR Measurement Performance
The JD-FAI955 integrates an industrial computer and a high-precision LCR electric bridge, powered by Subit’s in-house developed software system for fast, stable and accurate RLC measurement.
Key technical specifications:
- Average inspection speed: 3 seconds per component
- Test frequency range: 50 Hz to 100 kHz
- Basic measurement accuracy: 0.05%
- Minimum resolution: 0.05Ω (resistance); 0.1pF (capacitance)
- Ultra-wide measurement range:
  - Resistance: 0.01 mΩ – 99.9999 MΩ
  - Inductance: 0.01 nH – 9999.9 H
  - Capacitance: 0.00001 pF – 9.9999 F
- Automatic ranging: Software automatically selects the optimal measurement range and parameters
- 23.8-inch LCD display with OK/NG audible and visual prompts for intuitive operation
Smart Programming & Quality Traceability
Designed for real SMT production efficiency, the JD-FAI955 streamlines setup and quality management:
- Fast import of BOM tables and XY coordinates, with automatic bitmap matching
- Automatic extraction of component specifications from material descriptions
- Supports double-side coordinate import for single-side inspection
- Automatically identifies and marks blank positions
- Full-process test data logging, with Excel and PDF report export
- Test scenario playback for root cause tracing
- Optional server mode for centralized, unified FAI data management
