Single-Sided PCB Non-Metallized Hole Conducting Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-sided printed circuit boards are limited by only allowing connections on one side, which increases cost when metallized vias or holes are used, making them less economical compared to double-sided boards.
Innovation Solution
A single-sided printed circuit board with a non-metallized hole and a conducting bridge, such as a carbon print area, allows connections from the opposite side without using metallized vias, enabling contact through the bridge from the non-metallized side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-sided printed circuit board is used, then production cost is reduced, but connection capability from the opposite side is lost
Solution Approach 1:
A non-conductive bridge structure is introduced as an intermediary element. This bridge includes a bridge body extending from the first surface toward the second surface, with a conductive pattern on its side surface. The bridge provides a pathway for electrical connection from the opposite side without requiring metallized vias, thus maintaining low cost while enabling bidirectional connection capability.
2Adaptability or versatility
If metallized vias or holes are used to enable connections from the opposite side, then connection capability is improved, but production cost increases
Solution Approach 1:
The invention extracts the conductive function from the traditional via structure. Instead of metallizing the entire via hole (which is expensive), only the side surface of the bridge body is made conductive through a conductive pattern. This selective extraction of conductivity where needed reduces material and processing costs while maintaining connection capability.
Solution Approach 2:
The bridge structure implements local quality by having different conductivity characteristics in different regions. The bridge body is non-conductive in its interior, while the side surface has a conductive pattern. This localized conductivity provides the necessary electrical connection from the opposite side without the expense of fully metallized vias throughout the board.
