Circuit Board Traceability System with Code Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dust or oil adhering to the board ID code label on circuit boards can lead to erroneous reading of the board ID, resulting in incorrect traceability information being registered in the database.
Innovation Solution
A substrate work system that includes a compatibility conditions setting section to determine if the imaged identification code or serial number meets specific criteria before transmitting it to the information management device, ensuring accurate traceability information registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the board ID code label is read directly without verification, then the reading process is fast and simple, but erroneous readings occur when dust or oil adheres to the label
Solution Approach 1:
The system performs preliminary actions by setting compatibility conditions and verifying the imaged identification code against these conditions before final registration. The imaging control device checks whether the serial number meets predetermined compatibility conditions (such as format, length, or pattern requirements) before transmitting it to the information management device, preventing erroneous readings from being registered while maintaining efficient processing.
2Reliability
If compatibility verification is added to the reading process, then reading accuracy improves, but the processing time increases
Solution Approach 1:
The system applies partial verification by checking only essential compatibility conditions (such as format, length, or pattern matching) rather than performing exhaustive validation. This partial checking approach provides sufficient error prevention for typical cases while avoiding excessive processing time, balancing reliability improvement with time efficiency.

AI summary
A substrate work system including: an information management device configured to manage traceability information of configuration items that configure a circuit board product; an imaging device configured to image an identification code attached to the configuration item; and an imaging control device configured to read the identification code imaged by the imaging device, and transmit a serial number recorded in the identification code to the information management device, wherein the imaging control device includes a compatibility conditions setting section configured to set compatibility conditions that the identification code attached to the configuration item should satisfy, or compatibility conditions that the serial number recorded in the identification code should satisfy, a compatibility conditions determining section configured to determine whether the imaged identification code or the serial number recorded on the imaged identification code satisfies the compatibility conditions set by the compatibility conditions setting section, and a transmitting section configured to, in a case in which it is determined that the identification code or the serial number recorded on the identification code satisfies the compatibility conditions set by the compatibility conditions setting section, transmit the serial number to the information management device.
