PCB Design Verification System for XYRS and BOM Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of standardized XYRS and BOM files leads to faulty data, requiring manual re-creation by PCBA vendors, resulting in production errors, increased costs, and longer lead times for customers due to the non-standardized nature of these files and differences in footprint data between users and vendors.
Innovation Solution
A system that allows users to upload PCB design data, verify and input XYRS and BOM data visually, associating components with verified footprint data for automated assembly processes, using a server-connected network with a graphical user interface for data processing and verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual re-creation of XYRS and BOM data is performed by PCBA vendors, then data reliability may improve through verification, but production time increases and costs rise
Solution Approach 1:
The system performs preliminary verification and standardization of XYRS and BOM data through automated processing before the data reaches the PCBA vendor. The server validates data formats, checks component footprints, and ensures consistency with design files in advance, eliminating the need for time-consuming manual re-creation while maintaining high data reliability
Solution Approach 2:
An automated server acts as an intermediary between the design software and the PCBA vendor. This server receives design files, automatically generates and verifies XYRS and BOM data, performs footprint validation, and delivers standardized data to vendors. This intermediary processing layer ensures data reliability through systematic verification while maintaining rapid automated processing speeds
2Productivity
If standardized XYRS and BOM file formats are implemented, then processing speed and automation improve, but adaptability to different vendor requirements may worsen
Solution Approach 1:
The system implements configurable parameters that allow the standardization process to adapt to different vendor requirements. The server can adjust data formats, validation rules, and output specifications based on vendor-specific parameters while maintaining a core standardized processing framework. This enables high-speed automated processing with flexible adaptation to various vendor standards
Solution Approach 2:
The server is designed with multi-functional capabilities to handle multiple file formats and vendor requirements through a universal standardized interface. It can process various input formats (Gerber, ODB++, XML), generate standardized intermediate representations, and export to different vendor-specific formats, thereby achieving both high processing speed through automation and adaptability to diverse vendor requirements
3Manufacturing precision
If footprint data is verified and standardized before assembly, then manufacturing precision improves, but data processing complexity increases
Solution Approach 1:
The system implements self-service automated verification where the server autonomously validates footprint data against component libraries, checks coordinate consistency, verifies land pattern dimensions, and detects conflicts without requiring manual intervention. This automated self-verification ensures high manufacturing precision while managing processing complexity through algorithmic automation rather than manual procedures
