Solution Overview

Problem

Existing electronic components face reliability issues due to the presence of a space between the electronic device and the mounting board, which can lead to deformation and insufficient reliability, as the center of the semiconductor chip is not adequately supported in previous techniques.

Innovation Solution

The electronic component design includes a connecting member with a peripheral part and a central part, where the distance from the edge to the peripheral part is shorter than from the center, and the distance from the edge to the central part is longer, with a through hole communicating with the space between the device and the board, ensuring the center is not overlapped, thereby providing additional support and preventing deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a through hole is provided in the board to communicate with the space between the electronic device and the board, then the reliability is improved by preventing deformation, but the manufacturing complexity increases due to precise positioning requirements

Engineering Contradiction:

Improvereliability of electronic componentVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The connecting member is divided into a first part and a second part, with the first part positioned closer to the center of the electronic device and the second part positioned closer to the edge. This segmentation allows the through hole to be positioned in the board without overlapping the center of the electronic device, thereby maintaining reliability while simplifying manufacturing by avoiding complex alignment requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting member acts as an intermediary element between the board and the electronic device. It includes a first part and a second part that bridge the space between the board and the electronic device, allowing the through hole to communicate with the space while preventing direct overlap with the center of the electronic device, thus maintaining both reliability and manufacturing simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the connecting member is arranged to support the center of the electronic device, then the deformation is prevented, but the space between the electronic device and the board cannot be accessed for communication

Engineering Contradiction:

Improveplanarity of electronic deviceVSAvoidaccessibility of space

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connecting member is segmented into a first part and a second part. The first part is arranged between the first region (including the center) of the electronic device and the board, providing support to maintain planarity. The second part is arranged between the second region (edge area) and the board, allowing the space to communicate with the outside through the through hole in the board.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The solution transitions from a single-point support at the center to a distributed support system with the first part and second part of the connecting member positioned at different locations and heights. This dimensional distribution allows both center support for stability and space accessibility for communication.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If the through hole overlaps with the center of the electronic device, then the manufacturing is simplified, but the electronic device is deformed and reliability is insufficient

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidreliability of electronic component

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The connecting member is divided into a first part and a second part, with the first part positioned to provide support near the center region and the second part positioned near the edge. This segmentation enables the through hole to be positioned in the board without overlapping the center of the electronic device, preventing deformation while maintaining manufacturing simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting member has different parts with different functions: the first part provides support to prevent deformation near the center, while the second part allows space communication near the edge. This local differentiation of quality and function enables both manufacturing simplicity and high reliability.

Inventive Principle:

Principle #3Local quality
