PCB Pad Layout for Multi-Supplier RF Front-End Module Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of printed circuit boards (PCBs) in electronic devices is often tailored to specific electronic components, leading to increased costs and difficulties in accommodating components from different suppliers with varying designs, even if they have the same function, and making it challenging to change or differentiate components without redesigning the PCB.
Innovation Solution
A PCB design that includes designated areas with multiple pads and connection members, allowing for the mounting of electronic components with different designs without altering the PCB, enabling compatibility with various suppliers' components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the PCB design is tailored to specific electronic components, then the components can be properly mounted and connected, but the cost increases and it becomes difficult to accommodate components from different suppliers with varying designs
Solution Approach 1:
The patent implements a universal PCB pad layout design that can accommodate multiple different electronic component designs. The PCB includes designated areas with multiple pads arranged to support various component configurations, allowing the same PCB to work with components from different suppliers without requiring redesign. This multi-functional pad arrangement enables the PCB to serve multiple component types universally.
2Manufacturing precision
If the PCB design is customized for each component supplier's design, then precise connection is achieved, but development costs and production time increase
Solution Approach 1:
The patent employs preliminary action by pre-arranging multiple pads in designated areas on the PCB before component mounting. The pad locations are predetermined to accommodate various component designs, allowing components to be directly mounted and connected without requiring subsequent PCB modifications. This preliminary pad configuration ensures both precise connection and efficient production.
3Reliability
If the PCB design is changed to verify electronic components from various suppliers, then component compatibility is ensured, but design and production costs are wasted
Solution Approach 1:
The patent creates a universal PCB design with multi-purpose pad arrangements that can verify and accommodate components from various suppliers without requiring separate PCB designs. The same PCB can be used to test and mount different component variants, eliminating the need to manufacture multiple specialized PCBs and thereby reducing design and production costs while maintaining verification accuracy.
4Productivity
If a single PCB design is used for all component suppliers, then manufacturing efficiency is improved, but compatibility with various component designs may be compromised
Solution Approach 1:
The patent applies local quality by creating designated areas on the PCB with specific pad arrangements tailored for different component types. Each designated area has pads positioned to accommodate particular component designs, while the overall PCB maintains a unified structure. This localized adaptation within a global standard enables both manufacturing efficiency and component compatibility.
