Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnetic transmitting units are exposed without insulation, then signal transmission efficiency is improved, but the integrated circuit becomes vulnerable to electro-static discharge and electromagnetic interference
Solution Approach 1:
An electromagnetic insulating layer is introduced as an intermediary between the electromagnetic transmitting unit and the external environment. This insulating layer blocks electromagnetic interference and electro-static discharge from reaching the transmitting unit, while allowing the signal transmission function to continue operating effectively.
Solution Approach 2:
A thin electromagnetic insulating layer is applied over the electromagnetic transmitting unit. This thin film structure provides effective protection against ESD and EMI while maintaining the compact design and not significantly increasing the overall device volume.
2Reliability
If an electromagnetic insulating layer is added to protect against ESD and EMI, then reliability is improved, but device complexity increases
Solution Approach 1:
The electromagnetic insulating layer is implemented as a thin film structure that can be integrated into the existing device architecture. This approach provides comprehensive ESD and EMI protection without requiring complex multi-component assemblies, thereby minimizing the increase in device complexity.
Solution Approach 2:
The electromagnetic insulating layer is formed using composite material structures that combine multiple functional properties in a single layer, providing both electrical insulation and electromagnetic shielding capabilities while maintaining a simple overall structure.
