Abstract

Abstract: The rapid product iteration in the electronics manufacturing industry demands increased assembly efficiency. Three-Dimensional (3D) PCBA models offer intuitive guidance for assembly processes,yet most PCBA design files in manufacturing still exist as 2D drawings,which limits their ability to convey component layout,connectivity,and assembly details effectively. Current automated methods for constructing 3D PCBA models lack sufficient automation,making it challenging to transform numerous 2D design files into 3D models. This study introduced a parametric modeling-based technique for rapid 3D PCBA model construction to address the need for 3D visualization in electronic assembly. A structured data model was defined to meet the 3D assembly process requirements,facilitating the extraction of geometric and positional information from PCBA files for effective parsing. Subsequently,parametric feature modeling for components and PCB was proposed,followed by a coordinate-matching algorithm that enables automatic component positioning and PCB assembly. A case study validated the efficiency and accuracy of this method,showing its potential to construct precise 3D PCBA models efficiently,aiding assembly process guidance and enhancing manufacturing efficiency.
