Intelligent Solder Pad Positioning for Enhanced Inspection Accuracy

 

Our advanced Solder Pad Positioning and FOV-assisted alignment technology greatly reduce false calls caused by PCB deformation, warpage, silkscreen variation, and legend interference. This intelligent positioning is especially effective for FPC and post-wave-soldering boards, ensuring stable detection of solder joints and components. By improving alignment accuracy across the entire field of view, the system delivers more reliable inspection results and boosts overall SMT quality performance.

AOI System for SMT Assembly
Precise Poor Soldering Inspection for Chips and ICs


With accurate solder pad positioning and eight feature-point analysis, the system effectively identifies poor soldering defects on chips and ICs. By capturing solder shape abnormalities, insufficient solder, or weak joints, this technology delivers highly reliable inspection performance and ensures stable SMT assembly quality.

2D Automated Optical Inspection
IPC-Compliant Detection Parameters for Higher Accuracy

 

Our algorithm calculates component offsets based on IPC-A-610-G Class 3 standards, ensuring more reliable and consistent inspection results. By precisely positioning the solder pad and component body, the system accurately computes shift rate and detects overhang within the IPC-defined tolerance of less than 25%, delivering stable quality control for demanding SMT applications.
