Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data communication systems face challenges in maintaining high data transfer speeds while ensuring signal integrity, particularly due to signal degradation across separable interfaces in conventional electrical connector systems.
Innovation Solution
The electrical component features a multilayer package substrate with integrated circuits, where electrical signal traces and grounds are directly connected to the substrate without separable interfaces, allowing electrical cables to be mounted directly to the substrate, eliminating the need for separable connectors and thus preventing signal degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separable electrical connectors are used to connect electrical cables to integrated circuits, then ease of assembly and disassembly is improved, but signal integrity deteriorates due to signal degradation at separable interfaces
Solution Approach 1:
The patent merges the electrical cable termination directly with the integrated circuit package substrate by eliminating the separable connector interface. The electrical cable is bonded directly to contact pads on the substrate, creating a unified structure that removes the separable interface responsible for signal degradation, thereby maintaining signal integrity while still allowing for assembly and disassembly at the cable-substrate level.
2Reliability
If electrical cables are directly connected to integrated circuits without separable connectors, then signal integrity is improved by eliminating separable interfaces, but device complexity increases
Solution Approach 1:
The patent extracts the separable connector component from the electrical connection system, eliminating it entirely. By removing this intermediate component and directly bonding the electrical cable to the integrated circuit package substrate, the design simplifies the overall structure while improving signal integrity. The complexity is reduced by having fewer components and interfaces to manage.
