PCB Traceability via Printed Barcodes and Production Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current integrated circuits (ICs) modeling manufacturing processes lack a comprehensive monitoring and traceability mechanism, making it difficult to identify and correct errors during the modeling procedure.
Innovation Solution
A surface-mount technology (SMT) device prints a pattern with barcodes and production codes on a printed circuit board (PCB), which is then heated to secure the elements and pattern, allowing for traceable production information to be obtained and recorded, enhancing the traceability of the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a completely monitor mechanism is established during IC manufacturing, then wrong processes can be detected quickly, but no such monitoring mechanism exists during IC modeling process
Solution Approach 1:
The patent applies preliminary action by printing traceability patterns (barcodes and production codes) on the PCB before the modeling process begins. This allows the monitoring system to track the PCB through all subsequent manufacturing stages, enabling detection of wrong processes while maintaining traceability throughout the workflow.
Solution Approach 2:
The patent implements feedback by reading the traceability patterns at various stages of the modeling process and comparing them against the expected workflow. When deviations are detected, the system can identify wrong processes and provide feedback for correction, establishing a complete monitoring mechanism during IC modeling.
2Loss of information
If traceability patterns are printed on PCB during modeling, then production information becomes traceable, but additional manufacturing steps are required
Solution Approach 1:
The patent merges the traceability pattern printing step with the existing PCB manufacturing workflow. The patterns are printed on the PCB surface using standard printing techniques already employed in PCB fabrication, thereby adding traceability functionality without requiring separate dedicated equipment or complex additional manufacturing steps.
