Hinged CPU Socket Actuation for Compact Package Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The small size of pins in CPU sockets makes them susceptible to damage during seating, requiring a socket actuation mechanism (SAM) that occupies additional space on the PCB, necessitating a reduction in the horizontal and vertical footprint of the SAM to accommodate other resources.
Innovation Solution
A socket actuation mechanism with a socket frame, carrier frame, and force frame, where the carrier frame is rotatable via hinge portions and guide tabs, and the force frame is actuated to seat the die package without a rail frame, reducing the overall space and material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a socket actuation mechanism is used to ensure proper alignment and reduce pin damage, then reliability is improved, but the horizontal and vertical footprint increases
Solution Approach 1:
The carrier frame and force frame are merged into a single integrated assembly that performs both alignment and actuation functions. The force frame is coupled to the carrier frame through hinge portions, allowing the combined structure to rotate and seat the die package while applying force, eliminating the need for separate alignment and actuation mechanisms.
Solution Approach 2:
The carrier frame serves multiple functions: it holds the die package, provides alignment through guide tabs, and transmits actuation force through hinge portions to the socket frame. The force frame simultaneously provides structural support and applies the necessary force to seat the package, making the mechanism more space-efficient.
2Strength
If a rail frame is used in the socket actuation mechanism, then structural support is improved, but the overall space and material usage increases
Solution Approach 1:
The rail frame component is completely removed from the mechanism. Instead of using a rail frame for structural support, the invention relies on the hinge portions connecting the force frame to the carrier frame, and the guide tabs on the carrier frame, to provide the necessary structural support and guidance during actuation.
Solution Approach 2:
The mechanism is divided into discrete functional components: the carrier frame with guide tabs for alignment, the force frame for actuation, and hinge portions connecting them. This segmentation allows each component to be optimized for its specific function without requiring the bulky rail frame structure.
