Conventional X-ray detectors face challenges in efficiently installing and replacing modules due to susceptibility to mechanical stress, limited semiconductor area, and lack of mechanisms to prevent breakage or interference during handling and assembly, leading to decreased workability and increased risk of damage.
Innovation Solution
An X-ray detector design featuring a detection module with a protruding frame and a guide frame that allows for precise and easy installation/removal, along with a flexible wiring board and readout circuit substrate connected via high-density signal wirings, and a handle for safe handling, facilitating module replacement while minimizing space and reducing breakage risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If modules are arranged on a frame with rails to secure flatness and positioning, then the flatness and relative position of detection modules are improved, but the work load for installing and replacing modules increases significantly
Solution Approach 1:
The frame is divided into multiple guide frames, each capable of independently holding detection modules. This segmentation allows modules to be installed and removed individually without affecting the entire array, reducing the workload while maintaining positioning precision through each guide frame's independent guide grooves
Solution Approach 2:
Guide grooves are introduced as intermediary structures between the frame and detection modules. These grooves provide automatic positioning and guidance during module installation, eliminating the need for manual positioning work while ensuring precise flatness and relative positioning of modules
2Ease of manufacture
If detection elements and readout circuits are bump-bonded with fine solder balls, then the detector can be constructed with separate elements, but the detector becomes susceptible to mechanical impact and scratches
Solution Approach 1:
A protective structure is provided beforehand to cushion and protect the bump-bonded joints from mechanical impact and scratches. This protective structure absorbs external forces before they reach the fragile solder ball connections, maintaining both the ease of construction from separate elements and the mechanical robustness against damage
3Ease of manufacture
If wire bonding is performed on the readout circuit, then the circuit can be connected, but special care must be taken during assembly to avoid damage
Solution Approach 1:
Wire bonding is performed as a preliminary action before the final assembly stage. The readout circuits are pre-connected to detection elements through wire bonding while they are in a more accessible state, allowing complex circuit connections to be made beforehand without requiring special care during the final assembly operation

AI summary
To provide an X-ray detector facilitating the installing and replacement work of a module while reducing the possibility of breakage. An X-ray detector 50 detecting X-ray image data for each detection module includes: a detection module 7 provided with a protruding frame on a back side of a detection device detecting X-rays; and a guide frame 12 fitting into the protruding frame and removably supporting the detection device, wherein the guide frame 12 fixes the position of the detection device relative to the guide frame 12 by fitting. Therefore, fitting the protruding frame 8 into the guide frame 12 enables precise and easy installation/removal of the detection module. That is a detection module can be newly installed onto the guide frame without interfering each other with adjacent detection modules already installed while minimizing a space therebetween.
