Recessed Electronic Unit Layout for Ordered Fluid Transfer Bonding

Solution Overview

Problem

The fluid transfer process for electronic units often results in disordered placement, leading to increased difficulty in forming wires and abnormal electrical connections, which affects the yield of electronic devices.

Innovation Solution

The electronic device design includes a substrate with recesses that accommodate electronic units, where the size of the recess and unit, along with the number of signal connecting points, are optimized to ensure proper alignment and bonding, reducing the likelihood of abnormal electrical connections by maintaining a specific size relationship and pattern design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fluid transfer process is used to transfer electronic units to target substrate, then mass production is achieved, but electronic units are disposed in disordered arrangement

Engineering Contradiction:

Improvemass production capabilityVSAvoiddisorder of electronic units arrangement

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by pre-forming recesses in the target substrate before transferring electronic units. These recesses are designed with specific sizes and positions that guide the electronic units to settle in predetermined locations during the fluid transfer process, thereby achieving ordered arrangement without compromising mass production capability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces recesses as an intermediary structure between the electronic units and the target substrate. These recesses act as positioning features that mediate the transfer process, ensuring that electronic units are placed in correct positions while maintaining the efficiency of fluid transfer method

Inventive Principle:

Principle #24Intermediary (Mediator)
