Dual-PCB Assembly With IC Housing to Eliminate Board Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing field devices face challenges in efficiently connecting multiple circuit boards due to limited space and the need for modular systems, often relying on plugs and sockets that occupy additional space and lack additional functionality.
Innovation Solution
An electric assembly with integrated circuits in a housing connects circuit boards through metallized contact areas on the boards and housing, using soldering to create a sandwich structure, allowing for mechanical and electrical integration without separate connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plugs and sockets are used to connect circuit boards, then mechanical and electrical connection is achieved, but space consumption increases and device complexity increases
Solution Approach 1:
The housing is merged with the integrated circuit, and both are soldered directly to the circuit boards. This eliminates the need for separate plugs and sockets, reducing space consumption while maintaining reliable mechanical and electrical connection through the unified housing-IC assembly
Solution Approach 2:
The housing serves multiple functions: it provides mechanical support, electrical connection through contact areas, and houses the integrated circuit. This multi-functionality replaces the need for separate connector components, reducing overall device complexity and space requirements
2Reliability
If plugs and sockets are used to connect circuit boards, then mechanical and electrical connection is achieved, but device complexity increases
Solution Approach 1:
The housing and integrated circuit are combined into a single assembly that is soldered directly to the circuit boards, eliminating the need for separate plug and socket components. This reduces device complexity by integrating multiple functions into one assembly while maintaining reliable electrical connection
Solution Approach 2:
The separate plug and socket components are extracted from the system and replaced by direct solder connections between the housing/IC assembly and the circuit boards. This simplification reduces the number of parts and assembly steps while maintaining connection reliability
