Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic components face mounting failures due to electrode burrs on substrate terminals, which existing technologies have not adequately addressed, leading to issues such as short-circuits and positional deviations during assembly.
Innovation Solution
The electronic component design includes a conductor that covers the adjacent portions of the substrate terminal, specifically using solder to electrically connect the outer and mounting electrodes, thereby fixing any burrs and ensuring proper alignment and contact, reducing the occurrence of mounting failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a substrate terminal is used to mount the electronic element, then the electronic component can be assembled on a circuit substrate, but electrode burrs on the substrate terminal cause mounting failures such as short-circuits and positional deviations
Solution Approach 1:
The patent applies preliminary action by forming a conductor that covers the adjacent portion of the substrate terminal before the mounting process. This conductor is created in advance to prevent burrs from causing mounting failures, thereby eliminating the need for post-mounting corrections and ensuring reliable assembly from the outset
Solution Approach 2:
The patent introduces a conductor as an intermediary element between the substrate terminal and the mounting electrode. This conductor acts as a mediator that covers the adjacent portion of the substrate terminal, preventing direct contact between burrs and other electrodes, thus eliminating short-circuit risks while maintaining electrical connectivity
2Reliability
If the substrate terminal includes mounting electrodes for electrical connection, then electrical connectivity is achieved, but burrs on the mounting electrode cause short-circuits and mounting failures
Solution Approach 1:
The conductor serves as an intermediary that covers the adjacent portion of the substrate terminal where burrs are generated. This intermediary layer prevents burrs from causing short-circuits while maintaining the electrical connectivity function of the mounting electrode, thus resolving the contradiction between reliability and harmful factors
Solution Approach 2:
The patent extracts the harmful burrs from the functional mounting electrode by covering the adjacent portion with a conductor. This separation allows the mounting electrode to maintain its electrical connectivity function while the conductor isolates the burrs, preventing them from causing short-circuits or mounting failures
