LiQ Series SMT First Article Inspection (FAI) Systems
Precision, Efficiency, and Full Traceability for Modern Electronics Manufacturing
The Critical Role of First Article Inspection (FAI)
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 LiQ Series FAI systems from Suzhou Liqian Intelligent Technology are designed to replace this outdated method.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.
