Electronic Part Package with Segmented Supporting Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic part packages often lose stiffness and can warp after the supporting member is removed during the manufacturing process, leading to structural instability and potential functional issues.
Innovation Solution
An electronic part package design that includes a supporting member with isolated areas, where the electronic part is arranged in one area and a resin part covers it, with exposed terminals in a separate opening, and a wiring structure electrically connected to both the part and the terminals, while the supporting member remains to provide stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the supporting member is removed during manufacturing, then the electronic part package can be separated into individual components, but the package loses stiffness and warps due to structural instability
Solution Approach 1:
The supporting member is divided into a first area that supports the electronic part and a second area with openings for terminal exposure. This segmentation allows the supporting member to be retained for structural stability while still enabling component separation and terminal access functions.
2Loss of substance
If the supporting member is removed during manufacturing, then production costs can be reduced by eliminating unnecessary materials, but the package experiences warpage and mechanical property degradation
Solution Approach 1:
Instead of removing the entire supporting member, only specific portions are extracted: openings are formed in the second area to expose terminals, while the first area retaining the electronic part remains intact. This selective extraction maintains structural stability while achieving material efficiency.
3Strength
If the supporting member is retained in the package, then stiffness and structural stability are maintained, but the package complexity increases due to additional components
Solution Approach 1:
The supporting member serves multiple functions simultaneously: it provides structural stiffness and stability, supports the electronic part in the first area, enables terminal exposure through openings in the second area, and acts as a substrate for the wiring structure. This multi-functionality reduces overall package complexity despite retaining the supporting member.

AI summary
A disclosed electric part package includes a supporting member that includes a first area in which an electric part is arranged, and a second area in which a first opening is positioned, the second area being isolated from the first area; a resin part provided on the supporting member thereby to cover the electric part arranged in the first area, the resin part including an electric terminal exposed in the first opening of the supporting member; and a wiring structure provided on the resin part, the wiring structure being electrically connected to the electric part and the electric terminal of the resin part.
