Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current socket technologies use a single interconnect architecture for all pins, which is inadequate for testing integrated circuitry with varying signal frequencies, voltage ranges, and current levels, leading to increased costs and complexity in next-generation circuit testing.
Innovation Solution
The implementation of modular socket sub-assemblies with distinct zones, each customized for specific electro-mechanical characteristics to accommodate different signal requirements, allowing for segregation of interconnects based on performance needs.

Engineering Contradiction Analysis
1Adaptability or versatility
If a single interconnect architecture is used for all pins, then device complexity is reduced and manufacturing is simplified, but the socket cannot accommodate varying signal requirements (frequencies, voltage ranges, current levels) leading to increased testing costs
Solution Approach 1:
The socket is divided into multiple zones, each with distinct interconnect architectures tailored to specific signal requirements. High-frequency pins receive specialized interconnects with optimized electrical characteristics, while lower-frequency pins use standard interconnects, allowing the socket to accommodate varying signal requirements without uniform complexity across all pins.
Solution Approach 2:
Different interconnect architectures are applied to different spatial regions (zones) of the socket based on local signal requirements. Each zone is designed with specific electro-mechanical characteristics matched to the signal types that will be transmitted through that region, optimizing performance where needed while maintaining simplicity elsewhere.
2Reliability
If expensive materials are used for all interconnects, then signal transmission efficiency is improved across all pins, but manufacturing costs increase significantly
Solution Approach 1:
Premium materials and specialized interconnect structures are applied only to zones requiring high-frequency or high-performance signal transmission. Standard materials are used in zones with less demanding requirements, thereby maintaining signal transmission efficiency where needed while significantly reducing the quantity of expensive materials consumed across the entire socket.
Solution Approach 2:
The interconnect parameters (material composition, geometric dimensions, electrical characteristics) are varied by zone to match signal requirements. This allows optimization of signal transmission efficiency for critical pins while using cost-effective configurations for non-critical pins, balancing reliability and material consumption.
3Productivity
If zone-based configuration with modular sub-assemblies is implemented, then costs are reduced and signal transmission efficiency is enhanced, but device complexity and assembly difficulty increase
Solution Approach 1:
The socket is modularized into discrete zone-based sub-assemblies that can be independently manufactured and tested. This segmentation enables parallel production of different zone modules, improving overall manufacturing productivity and allowing customization for different testing scenarios without requiring complete redesign of the entire socket.
Solution Approach 2:
The modular zone sub-assemblies are designed with standardized interfaces and mounting mechanisms that allow them to be universally assembled in various configurations. This multi-functionality enables the same modular components to serve different testing requirements, enhancing productivity while controlling assembly complexity through standardization.

AI summary
Techniques and mechanisms for providing socket connection to a substrate. In an embodiment, a socket device includes a first socket body portion that is to provide for signal exchanges as part of a socket connector including the first socket body portion and a second socket body portion. The first socket body portion and the second socket body portion comprise respective zones, wherein, of the two zones, only one such zone has a first electro-mechanical characteristic. The first electro-mechanical characteristic is selected from the group consisting of an interconnect dimension, an interconnect material, an interconnect structure, a socket body material, and a shielding structure. In another embodiment, modular socket sub-assemblies each comprise a respective one of the first zone and the second zone.
