Terminal Angle Layout for High-Speed Electronic Module Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic modules, the spacing between terminals changes during assembly, leading to poor signal integrity, especially at high speeds, due to the deviation of bent terminal parts under friction forces, resulting in distorted signals and increased impedance and crosstalk.
Innovation Solution
The electronic module design includes terminals with a body part and a first bent part, where the torque from the friction force is minimized by adjusting the angle between the bent part's extension direction and the sliding direction, ensuring the bent part does not rotate, maintaining consistent spacing and reducing impedance and crosstalk, with specific material choices like copper alloy and phosphor bronze, and optimized terminal arrangements to offset friction forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bent part of the terminal is designed with a conventional 45° angle, then the assembly process is simple, but the bent part deviates under friction force during sliding, changing the spacing between terminals and degrading signal integrity
Solution Approach 1:
The patent changes the critical parameter of the bent part angle from the conventional 45° to a specific range (0°-15° or 75°-90°). This parameter modification ensures that the friction force during sliding acts along the extension direction of the bent part rather than causing deviation, thereby maintaining terminal spacing and signal integrity while still allowing for straightforward assembly processes
2Reliability
If the bent part angle is adjusted to minimize friction torque, then signal integrity is maintained, but the terminal structure becomes more complex
Solution Approach 1:
Rather than adding complex mechanisms or structures, the patent achieves improved signal integrity by simply modifying the angular parameter of the existing bent part structure. The optimized angle range (0°-15° or 75°-90°) allows the terminal to maintain its spacing during assembly without requiring additional components or complex structural modifications
