PCB Through-Hole Connector Layout to Eliminate Double Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of mounting connectors on the lower surface of a printed circuit board after mounting light sources and components on the upper surface increases process time and cost due to the double process.
Innovation Solution
A connector is mounted on the upper surface of the printed circuit board, providing electrical connections between the upper and lower surfaces, and includes terminals on the upper surface to connect adjacent portions of the board, with a connecting member protruding below to connect to power and control assemblies through wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector is mounted on the lower surface of the printed circuit board after mounting light sources and components on the upper surface, then the electrical connection between upper and lower surfaces is achieved, but the processing time and manufacturing cost increase due to the double process
Solution Approach 1:
The patent inverts the conventional mounting sequence by mounting the connector on the upper surface of the printed circuit board first, before mounting the light sources and components. This reversal eliminates the need for a separate lower surface mounting process, reducing processing steps while maintaining reliable electrical connections between upper and lower surfaces through the connector body that extends through the board
2Reliability
If the connector is mounted on the lower surface of the printed circuit board, then the electrical connection is established, but the device complexity and manufacturing steps increase
Solution Approach 1:
The patent merges the connector mounting process with the upper surface component mounting process. The connector is mounted on the upper surface alongside other components, and its body extends through the printed circuit board to provide electrical connections. This consolidation reduces the number of separate manufacturing steps and simplifies the overall mounting process while maintaining connection reliability
3Reliability
If the connector is mounted on the lower surface of the printed circuit board, then the electrical connection is achieved, but the manufacturing cost increases due to additional process steps
Solution Approach 1:
The patent inverts the conventional mounting sequence by mounting the connector on the upper surface first, which eliminates the need for a separate lower surface mounting process. This reduction in manufacturing steps directly lowers production costs while maintaining reliable electrical connections through the connector body that extends through the printed circuit board
