Antenna Base Mounting Structure for Chip Positioning Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna devices face challenges in maintaining physical and electrical connections with mounting terminals due to positional displacement of chip electronic components during reflow soldering.
Innovation Solution
The antenna device incorporates a base with an uneven portion at the edge of the opening, featuring a recess and a protrusion that aligns with the mounting terminals, creating a mounting space for the chip electronic component to ensure proper positioning and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If protrusions are provided on the terminal member to prevent positional displacement, then positioning accuracy is improved, but device complexity and material requirements increase
Solution Approach 1:
The positioning function is extracted from the terminal member and transferred to the base. The base now carries the protrusions that provide positioning, while the terminal member returns to its simpler original form without requiring additional protrusions or structural modifications.
Solution Approach 2:
The base acts as an intermediary structure that provides positioning features (protrusions) to the mounting assembly. This mediator structure enables accurate positioning without requiring the terminal member itself to be modified with complex features.
2Manufacturing precision
If the terminal member material has suitable plasticity and toughness for protrusions, then positioning capability is improved, but material selection constraints increase
Solution Approach 1:
The positioning function is extracted from the terminal member material requirements and assigned to the base structure. This removes the constraint that terminal member materials must have specific plasticity and toughness, allowing broader material selection for the terminal member while the base provides the positioning capability through its own structure.
3Stability of the object's composition
If terminal member thickness is increased to provide protrusions, then positioning stability is improved, but device dimensions increase
Solution Approach 1:
The positioning stability function is extracted from the terminal member thickness and assigned to the base structure. The base provides the necessary thickness and structural support for stable positioning through its protrusions, while the terminal member can maintain its original thin profile without requiring increased thickness.

AI summary
An antenna device includes a base having a mounting portion, and a chip electronic component. The land includes at least a pair of mounting terminals for mounting the capacitor chip. The base has an uneven portion formed at an edge portion of an opening. The uneven portion includes a recess and a protrusion, and protrudes and is recessed in a direction in which the mounting terminals that form a pair are aligned at the edge portion of the opening. The protrusion defines a mounting space at a position where at least a pair of terminals of the capacitor chip faces the mounting terminals that form a pair.
