Precision, Efficiency, and Full Traceability for Modern Electronics Manufacturing
In Surface Mount Technology (SMT), the First Article Inspection is a mandatory quality gate. It is performed on the first product (or a few pieces) produced at the start of a shift, after a process change, or following equipment adjustment. Its purpose is to prevent costly mass production failures by identifying issues like wrong or missing components, incorrect polarity, or poor soldering before full-scale production begins.
Manual FAI, which relies on paper drawings, spreadsheets, and multimeters, is time-consuming and prone to human error. LiQ Series FAI systems from Suzhou Liqian Intelligent Technology are designed to replace this outdated method. They integrate hardware and software to automate electrical testing and visual verification, ensuring a fast, accurate, and fully documented FAI process.

Liqian's LiQ Series offers a complete lineup to match any production requirement, from entry-level to high-end automation.
Model | Core Positioning | Key Features & Highlights |
|---|---|---|
LiQ-300 | Economical & Entry-Level | ? One-person operation, reducing labor costs. |
LiQ-550/550S | Standard /Vision | ? Designed for mainstream PCBs (consumer, industrial control). |
LiQ-560 | Large-Board Specialist | ? Built for large-format PCBs (servers, new energy, telecom). |
LiQ-750 | Fully Automatic Probing | ? Combines electrical test (with probes) and vision inspection. |
Automated Electrical Testing: Integrated with a high-precision LCR meter to automatically measure component values and compare them against the BOM, eliminating manual errors.
Comprehensive Visual Verification: Uses high-resolution cameras to check component presence, polarity, and markings against CAD data and scanned images.
Smart Software Core: Features automatic BOM/XY data comparison to catch errors, intelligent test sequencing to minimize cycle time, and on-screen magnification for easy review.
Seamless Reporting & Traceability: Automatically generates detailed FAI reports and supports data export to MES/ERP systems for full process traceability and compliance auditing.

LiQ Series FAI systems are trusted in industries where quality and compliance are non-negotiable:
Automotive Electronics: For IATF 16949-compliant documentation and zero-defect requirements.
Medical Devices: To ensure the reliability of life-critical electronics.
Industrial & Communications: For high-mix, high-reliability applications.
Consumer Electronics: To support fast product iterations and stringent quality control.
Liqian Intelligent Technology provides a scalable FAI solution that grows with your business. Starting with an LiQ-300 and upgrading later, or implementing a fully automatic LiQ-750, the system ensures a smooth quality journey.
