IC Package Connector Layout to Withstand Resin Thermal Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability of electrical connections in electronic devices is compromised due to stress applied by the deformation of reinforcing resin caused by temperature changes, which affects the connection between IC packages.
Innovation Solution
The electronic device incorporates a reinforcing member made of resin that contacts the IC packages, with electrical connectors positioned to avoid direct stress application by being dislocated from the resin's facing portion, thereby maintaining connection reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcing resin is used to ensure electrical connection reliability between IC packages, then connection strength is improved, but stress is applied to electrical connectors due to resin deformation from temperature changes
Solution Approach 1:
The patent extracts the harmful portion of the electrical connector (the section that would be subjected to stress) from the stress zone by dislocating it from the member facing portion of the reinforcing resin. This separates the electrical connection function from the stress-prone area, allowing the connector to maintain reliability while the resin provides reinforcement.
Solution Approach 2:
The patent introduces an intermediary spatial arrangement where the electrical connector's signal transmission path is routed away from the reinforcing resin's facing portion. This intermediary positioning allows the resin to perform its reinforcement function without directly transmitting stress to the electrical connection points.
2Reliability
If electrical connectors are positioned to avoid stress from reinforcing resin, then electrical connection reliability is improved, but device complexity increases due to dislocated positioning
Solution Approach 1:
The patent merges the reinforcing resin structure with the electrical connector design by integrating the dislocated connector sections into the overall connector architecture. The connector is designed as a unified structure that inherently accounts for the dislocated positioning, eliminating the need for separate complex positioning mechanisms.
Solution Approach 2:
The patent applies local quality by making different sections of the electrical connector have different positional characteristics. Specific sections are dislocated from the member facing portion while other sections maintain standard positioning, allowing the connector to optimize for both stress avoidance and structural integration.
