QR Code Marking for IC Package Manufacturing Parameter Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manual review of paper documents for manufacturing processes, such as PPAP, PSW, PCN, EOL, and BOM, leads to increased manufacturing errors, inefficiencies, and time-consuming logistics due to human error and the complexity of coordinating operations between suppliers, customers, and subcontractors.
Innovation Solution
The use of QR codes to encode information on paper documents, allowing for automated processing and scanning to extract parameters, enabling faster data comparison and synthesis, and improving traceability and logistics efficiency by linking documents and products through unique identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual review of paper documents is used for manufacturing processes, then human operators can review and process information, but manufacturing errors increase and efficiency decreases due to human error and coordination complexity
Solution Approach 1:
The patent replaces the manual mechanical review process with an automated optical scanning system. QR codes are scanned by imaging devices (cameras, scanners) and processed by programmable processors, eliminating human manual review and reducing errors while improving efficiency.
Solution Approach 2:
The patent creates digital copies of manufacturing parameters through QR codes that encode document identifiers and parameter data. These digital copies can be rapidly scanned and processed multiple times without degradation, replacing physical document handling.
2Ease of operation
If manual coordination between suppliers, customers, and subcontractors is used, then communication can occur, but time-consuming logistics and coordination inefficiencies occur
Solution Approach 1:
The patent creates machine-readable copies of manufacturing parameters through QR codes that can be rapidly scanned and processed. This eliminates manual document handling and coordination, significantly reducing logistics time while improving coordination efficiency through automated data extraction and comparison.
3Loss of information
If paper documents are used for manufacturing parameters, then information can be documented, but data extraction and comparison become slow and error-prone
Solution Approach 1:
The patent replaces manual data extraction and comparison with automated optical scanning and digital processing. QR codes encode manufacturing parameters that can be rapidly scanned by imaging devices and processed by computers, eliminating manual data entry errors and dramatically increasing processing speed.
Solution Approach 2:
The patent creates machine-readable digital copies of manufacturing parameters through QR codes. These encoded copies can be rapidly scanned and processed multiple times without degradation, ensuring data accuracy while dramatically improving processing speed compared to physical document handling.
Data Source
AI summary
A package for an integrated circuit is marked with an encoded image (e.g., a two-dimensional barcode). The encoded image is scanned by a scanner to obtain manufacturing parameters. In one approach, a method includes: fabricating, in a manufacturing facility, a physical product using a manufacturing process, where the physical product is fabricated according to specifications, and the manufacturing process includes manufacturing steps performed in the manufacturing facility; marking the physical product with an encoded image, where the encoded image encodes parameters that include the specifications; and transporting the physical product to a storage facility, where the storage facility includes a scanner configured to scan the encoded image to obtain the parameters.
