RFIC Tag Manufacturing Density Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID tag manufacturing methods using carrier tapes face challenges in increasing productivity and ensuring attachment position accuracy when continuously attaching RFIC elements to antenna substrates.
Innovation Solution
The method involves arranging RFIC elements in a housing tool at a first density and extracting a group with a lower second density matching the antenna patterns on the substrate, using a transfer sheet and mask with through-holes to maintain alignment and accuracy during disposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If RFIC elements are continuously attached one by one to the antenna substrate, then attachment position accuracy can be ensured, but productivity increases are limited
Solution Approach 1:
The patent segments the RFIC elements into groups corresponding to antenna pattern groups on the substrate. Instead of attaching individual RFIC elements one by one, multiple RFIC elements are attached as a group in a single operation, thereby improving productivity while maintaining attachment position accuracy through the grouped arrangement.
Solution Approach 2:
The patent prepares the RFIC elements in advance by arranging them in a housing tool at a first arrangement density that corresponds to the antenna pattern arrangement on the substrate. This preliminary arrangement allows for efficient group extraction and attachment, improving both productivity and position accuracy.
2Productivity
If RFIC elements are arranged at high density in the housing tool, then productivity can be increased, but attachment position accuracy may deteriorate
Solution Approach 1:
The patent employs a dynamic arrangement strategy where RFIC elements are arranged at a first arrangement density in the housing tool that is higher than the second arrangement density on the substrate. During the extraction and attachment process, the system dynamically selects and extracts only the necessary RFIC element groups at the appropriate second density, thereby achieving both high productivity and accurate attachment positions.

AI summary
An RFID tag manufacturing method is provided that includes arranging a plurality of RFIC elements in a housing tool at a first arrangement density; and extracting an RFIC element group out of the plurality of RFIC elements arranged in the housing tool. Moreover, the extracted RFIC element group has a second arrangement density that is lower than the first arrangement density and that corresponds to an arrangement density of a plurality of antenna patterns arranged on an antenna substrate. The method includes disposing the RFIC element group onto the plurality of antenna patterns of the antenna substrate while maintaining the second arrangement density.
