Flexible Radiation Detector Reinforcement for Support Base Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal of a support member from a flexible base member in radiation detector manufacturing often results in bending of the peripheral region, leading to cracking of wiring patterns and decreased yield due to the lack of support in regions not covered by the protective layer.
Innovation Solution
A reinforcing member is positioned in contact with the peripheral region of the flexible base member, overlapping it in orthogonal projection but not the scintillator, to stabilize the structure during support removal, thereby preventing deformation and cracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the support base is removed from the flexible base member to enable lightweight construction, then the weight of the radiation detector is reduced, but the peripheral region of the base member bends and wiring patterns crack
Solution Approach 1:
A reinforcing member is arranged in contact with the peripheral region of the flexible base member before the support base is removed. This preliminary reinforcement prevents bending and cracking of wiring patterns during the support removal process, while still allowing the final product to be lightweight.
Solution Approach 2:
The reinforcing member is specifically positioned only in the peripheral region that is not covered by the protective layer, providing localized reinforcement where it is most needed to prevent bending, while leaving the central pixel region unchanged for optimal detection performance.
2Ease of operation
If the peripheral region of the base member is left uncovered to maintain flexibility and lightweight structure, then the base member remains flexible and lightweight, but the peripheral region bends easily causing wiring pattern failure
Solution Approach 1:
The reinforcing member is selectively placed only in the peripheral region not covered by the protective layer, providing localized strength enhancement where needed while preserving the flexibility and lightweight characteristics of the covered central region.
Solution Approach 2:
The reinforcing member is installed before support base removal to preemptively strengthen the vulnerable peripheral region, preventing bending and wiring failure while maintaining the overall flexible design.

AI summary
A radiation detector manufacturing method is provided. The method includes: preparing a structure including a support base, a flexible base member arranged on the support base and having a principal surface including a pixel region in which a plurality of pixels are arranged, a scintillator arranged so as to cover the pixel region, and a protective layer arranged so as to cover the scintillator; and removing the support base from the flexible base member. The principal surface includes a peripheral region not covered with the protective layer. The method further includes, before the removing, arranging a reinforcing member in contact with the peripheral region, in a position overlapping the peripheral region and not overlapping the scintillator, in orthogonal projection to the principal surface.
