Hardware and Software Synergy | Core Software Functions for Professional PCB Measurement

High-precision PCB measurement relies not only on excellent optical and mechanical hardware, but also on professional supporting measurement software. As the core carrier of optical dimensional measurement data calculation, program control and quality analysis, customized industrial software determines the overall operating efficiency and detection accuracy of PCB measurement equipment. SIG self-developed measurement software is deeply optimized for PCB industry scenarios, realizing efficient synergy with hardware to complete full-process professional PCB measurement.

The intelligent workpiece coordinate system and automatic alignment function greatly simplify PCB inspection operations. Operators can set benchmark edges, positioning holes or MARK points as positioning references. The system automatically calculates rotation compensation for randomly placed PCBs, eliminating manual alignment operations. For multi-unit PCB panels, independent coordinate systems can be established for each sub-board to facilitate array batch detection and improve programming efficiency.

Diversified geometric measurement tool sets cover all conventional PCB detection items. The built-in straight line, circle, arc and rectangle tools support one-click measurement of PCB board edges, through-holes, rounded corners and slots. The system automatically calculates aperture, hole center coordinates, hole spacing and contour dimensions. Multiple edge recognition algorithms and filtering modes are available to adapt to solder mask surfaces, copper foil areas and milling edges of PCBs, suppressing image noise and ensuring stable feature extraction. Manual point selection function is reserved for complex workpieces to guarantee data accuracy.

The dual programming mode adapts to diversified production modes. Manual rapid programming is applicable for multi-variety and small-batch prototype sampling, completing first-article PCB measurement quickly without complex parameter setting. Automatic program programming is suitable for mass production; saved programs including motion paths, light source parameters and magnification ratios can be called cyclically. The array replication function greatly reduces repeated programming work for panel workpieces, and programs support iterative modification for upgraded PCB versions.

Intelligent tolerance judgment and diversified data output optimize quality management. Operators can pre-set upper and lower tolerance limits according to PCB drawings. The system automatically compares measured values with standard values to realize real-time OK/NG judgment, visually displaying out-of-tolerance positions. It supports one-click export of PDF inspection reports with workpiece screenshots and Excel original data files for SPC statistical analysis, realizing full data traceability of PCB quality inspection.

The CAD drawing comparison function is a practical core function for PCB process optimization. By importing DXF standard drawings, the system realizes superposition comparison between actual measured contours and theoretical dimensions, visually displaying overall offset and local dimensional deviation through color difference distribution, helping engineers quickly locate process problems such as milling parameter drift and CAM data errors.

In terms of intelligent control, the software automatically controls hardware actions such as lens magnification switching and light source mode adjustment according to program settings, realizing unattended automatic measurement. The multi-level authority management function standardizes factory operation specifications, preventing misoperation of mature mass production programs by ordinary operators. Through perfect hardware and software synergy, SIG video measuring machines maximize the efficiency and accuracy of optical dimensional measurement for PCB manufacturing.
