Integrated Circuit Package Mechanical Element Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integrated circuit packages lack robust and reliable mechanical fixation and external connection solutions, especially in harsh environments and for sensitive sensors, which can be damaged by vibrations and require precise centering and cooling.
Innovation Solution
Incorporating a mechanical element such as an attachment, bushing, or bearing element within the integrated circuit package, which provides mechanical and electrical connections, allowing for robust mounting, centering, and cooling, while maintaining protection of sensitive components through a durable package material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If no mechanical element is provided in the integrated circuit package, then the package structure remains simple, but the mechanical fixation and centering capability is insufficient
Solution Approach 1:
The patent combines multiple functions into a single mechanical element: attachment (fixation), centering, and sealing. This element integrates what would otherwise require separate components, providing robust mechanical fixation while avoiding the complexity of multiple discrete parts.
Solution Approach 2:
The mechanical element is designed to perform multiple functions simultaneously: it provides mechanical attachment to secure the package, centers the integrated circuit within the package, and creates sealing surfaces for environmental protection. This multi-functionality resolves the contradiction by achieving strong fixation without adding proportional complexity.
2Reliability
If a mechanical element is added for robust mounting, then the mechanical fixation is improved, but the device complexity increases
Solution Approach 1:
The mechanical element merges attachment, centering, and sealing functions into one component, achieving reliable operation through integrated design rather than multiple separate elements that would increase complexity.
Solution Approach 2:
The mechanical element is pre-formed with integrated features (attachment surfaces, centering geometry, sealing surfaces) before assembly. This preliminary integration of functions reduces the complexity that would arise from assembling multiple separate components during package assembly.
3Ease of operation
If external connection elements are provided without a mechanical element, then the electrical connection is possible, but the mechanical connection for cooling and mounting is insufficient
Solution Approach 1:
The mechanical element is designed to accommodate multiple external connection types: mechanical mounting attachments, thermal cooling connections, and alignment features for electrical connections. This universal interface approach enables diverse external connections while maintaining strong mechanical connection through a single robust element.
4Reliability
If the package material fully encloses the integrated circuit, then the protection is maximized, but the mechanical element cannot be accessed for connection
Solution Approach 1:
The package material is configured to provide full enclosure and protection for the integrated circuit, while the mechanical element extends through or beyond the package material at specific locations. This local differentiation allows maximum protection where needed while maintaining accessibility for external connections where required.
Solution Approach 2:
The mechanical element is integrated into the package structure such that it is nested within or extends from the package material. The package material encloses the sensitive integrated circuit while the mechanical element remains accessible, creating a nested arrangement that resolves the contradiction between protection and access.
