Processor Loading Frame Reduces Board Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional processor loading systems occupy valuable space on circuit boards due to the need for multiple mounting holes and fasteners, which limits the area available for trace routing and other components.
Innovation Solution
A modular system comprising a circuit board, a frame, a backing plate, and fasteners that securely attach the frame and backing plate to the circuit board using fewer holes, allowing for efficient mechanical loading of processors while minimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional loading mechanisms with multiple mounting holes and fasteners are used, then the processor can be securely mounted to the socket, but valuable board space and volume adjacent to the socket are consumed
Solution Approach 1:
The loading mechanism merges the frame and backing plate into a single integrated assembly that attaches to the circuit board as one unit. This consolidation eliminates the need for separate mounting operations and reduces the total number of mounting holes required, thereby securing the processor while minimizing board space consumption.
Solution Approach 2:
The frame and backing plate assembly serves multiple functions simultaneously: it provides mechanical support for the processor, ensures proper alignment with the socket, secures the processor through fasteners, and minimizes board space usage. This multi-functionality allows a single structure to replace what would traditionally require multiple separate components and mounting operations.
2Ease of manufacture
If six to eight mounting holes are defined in the board, then the loading mechanism and heatsink can be mounted, but valuable volume and board space that could be used for trace routing or other components is lost
Solution Approach 1:
The loading mechanism combines the frame and backing plate into a single assembly that requires fewer mounting holes than traditional separate components. This merging reduces the number of holes from six to eight down to fewer mounting points, thereby preserving board space for trace routing and other components while maintaining ease of manufacture through the integrated design.
3Reliability
If multiple fasteners and mounting holes are used, then the processor loading system is secure and reliable, but the device complexity and space requirements increase
Solution Approach 1:
The frame and backing plate are merged into a single integrated assembly, reducing device complexity by eliminating the need for separate mounting operations for each component. This unified structure maintains reliable processor loading security through its fastener system while reducing overall structural complexity and the number of individual parts required.

AI summary
In a component loading system, a circuit board may include a socket, a first plurality of holes, and a second plurality of holes. A frame may include two opposing sidewalls each substantially perpendicular to a surface of the circuit board and coupled to one another via a plate, a plurality of threaded channels, each channel adjacent to one of the two opposing sidewalls and located between the two opposing sidewalls, and a third plurality of holes. A backing plate may include a plurality of heat dissipater mounting posts and a fourth plurality of holes. A plurality of second fasteners may each be mechanically engaged to a respective one of the plurality of threaded channels and passing through a respective one of the second plurality of holes to mechanically secure the frame and backplate on opposite sides of the circuit board.
