Base Tape Guide Recess Structure for Stable Component Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional base tapes for electronic components face challenges in stable lateral insertion due to the lack of adequate guiding features, leading to potential snagging or riding of components on the tape surface, especially for components with small clearance.
Innovation Solution
The base tape design incorporates a pair of inclined portions on opposing sides of the accommodation recess, with the first inclined portion guiding the component and the second portion ensuring stable insertion by reducing turning and surface contact, thereby preventing snagging and riding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one inclined guide recess is provided on one side of the accommodation recess, then the insertion process is simplified, but the electronic component may get snagged on corners or ride on the upper surface of the base tape
Solution Approach 1:
The patent applies asymmetry by providing inclined guide recesses only on specific sides (one long side and one short side) of the rectangular accommodation recess, rather than symmetrically on all sides. This asymmetric configuration creates a guided insertion path that prevents the electronic component from snagging on corners or riding on the upper surface, while maintaining structural simplicity.
Solution Approach 2:
The inclined guide recesses act as intermediary elements between the electronic component and the accommodation recess. These guide recesses provide a gradual transition path that mediates the insertion process, guiding the component smoothly into place and preventing direct contact with problematic corners or the upper surface.
2Manufacturing precision
If the clearance between the electronic component and accommodation recess is small, then the accommodation is more precise, but the component is more likely to get snagged during insertion
Solution Approach 1:
The inclined guide recesses perform preliminary guiding action before the electronic component enters the main accommodation recess. This preliminary guidance establishes the correct insertion trajectory in advance, ensuring that even components with small clearances can be inserted smoothly without snagging, while maintaining precise accommodation.
