Solution Overview

Problem

The challenge lies in miniaturizing electronic devices with multiple package components on a circuit board while reducing signal transmission loss and addressing manufacturing difficulties due to component displacement during assembly.

Innovation Solution

An electronic device comprising a base layer with via structures, a redistribution structure, electronic units, and a protecting layer, where the units are electrically connected through the redistribution structure and via structures, allowing for miniaturization and improved signal transmission by packaging the units together with a connecting component.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple package components are disposed on a circuit board to integrate various functions, then device functionality is improved, but the size of the entire structure increases

Engineering Contradiction:
Improvedevice functionalityVSAvoidsize of entire structure
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent implements nesting by placing multiple package components (first package component and second package component) within a single package body. The first package component is disposed on the circuit board, and the second package component is disposed on top of or adjacent to the first package component, both enclosed within the same package body with sealing structure. This nested arrangement allows multiple functional components to be integrated in a compact space, reducing the overall footprint while maintaining diverse functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Loss of energy

If multiple package components are disposed on a circuit board to reduce distances between them, then signal transmission loss is reduced, but the entire structure cannot be further thinned or miniaturized due to process limitations

Engineering Contradiction:
Improvesignal transmission lossVSAvoidminiaturization process complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent transitions from a two-dimensional arrangement of components on the circuit board surface to a three-dimensional structure by stacking package components vertically within a package body. The first package component is positioned on the circuit board, and the second package component is positioned in the vertical dimension above or beside it, enclosed by the package body. This vertical stacking reduces horizontal distances between components, minimizing signal transmission loss while achieving miniaturization without excessive process complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If multiple package components are designed to be electrically connected to each other, then device functionality is improved, but manufacturing difficulty increases due to component displacement during assembly

Engineering Contradiction:
Improvedevice functionalityVSAvoidmanufacturing difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies preliminary action by pre-disposing the first package component on the circuit board and pre-configuring its electrical connection structures (such as connection pads or terminals) before assembling the second package component. The package body is also prepared with corresponding sealing structures and opening positions in advance. This preliminary arrangement of components and connection structures simplifies the assembly process, reduces manufacturing difficulty, and ensures proper electrical connections while maintaining improved device functionality.

Inventive Principle:
Principle #10Preliminary action
