Antenna Terminal Positioner for Chip Capacitor Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna devices face issues with positional deviation of chip capacitors during soldering, leading to potential soldering failures due to the liquefaction of solder paste, which can cause the capacitors to float and become misaligned on metal terminals.
Innovation Solution
The antenna device incorporates a chip-support-piece portion with protrusions, positioning concave-portions, or bent portions that serve as positioners to prevent positional deviation of the chip capacitor by providing a stable surface for alignment and fixing during soldering, ensuring accurate placement and preventing soldering failures.

Engineering Contradiction Analysis
1Reliability
If solder paste is used to attach the chip capacitor to the metal terminal, then the capacitor can be electrically connected, but the solder paste liquefies during soldering causing the capacitor to float and become positionally-deviated
Solution Approach 1:
The chip-support-piece portion is provided with positioners (protrusions or concave-portions) before the soldering process. These positioners preliminarily position and fix the chip capacitor in the correct location, preventing any positional deviation during the subsequent soldering process when the solder paste liquefies.
Solution Approach 2:
The positioners on the chip-support-piece portion act as an intermediary mechanism between the chip capacitor and the metal terminal. They provide a stable reference structure that mediates the positioning function, ensuring the capacitor remains in the correct position even when the solder paste is in liquid state during soldering.
2Device complexity
If the chip capacitor is mounted directly on the metal terminal without positioners, then the structure is simpler, but the capacitor becomes positionally-deviated during soldering
Solution Approach 1:
The chip-support-piece portion is segmented to include specific positioners (protrusions or concave-portions) that are dedicated solely to the positioning function. This segmentation allows the positioning function to be separated from the support function, achieving precise positioning without significantly increasing overall structural complexity.
Solution Approach 2:
The positioners are provided only at specific locations on the chip-support-piece portion where positioning is needed, rather than making the entire structure more complex. This local quality approach applies the positioning function only where necessary, maintaining simplicity in other areas of the structure.
