Solution Overview

Problem

The challenge in manufacturing laminate-type component carriers lies in achieving high spatial accuracy due to misalignment issues during the assembly of components on the carriers, which can lead to functional losses if not properly addressed.

Innovation Solution

A method and apparatus that detect misalignment in structural features of component carriers using image detection and identification units, allowing for the modification of the target design for correlated structural features to compensate for misalignment, thereby maintaining the misaligned features while adjusting the design for subsequent manufacturing steps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If misalignment is detected and compensated by modifying target design of correlated structural features, then manufacturing precision is improved, but device complexity increases due to additional detection and design modification steps

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by detecting misalignment of structural features before subsequent manufacturing steps and pre-compensating for it by modifying the target design of correlated features. This advance detection and design adjustment prevents compounding errors and ensures final alignment accuracy without requiring physical corrections later in the manufacturing process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a modified target design that replicates the intended structural features with corrected positional information. Instead of physically adjusting already-manufactured features, the system creates a digital copy of the design with compensating modifications that guide subsequent manufacturing steps to achieve proper alignment.

Inventive Principle:
Principle #26Copying

2Productivity

If misalignment is compensated by modifying target design rather than physically correcting features, then productivity is improved by avoiding rework, but manufacturing precision may be compromised without accurate detection systems

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent replaces mechanical physical correction methods with an information-based system. Instead of using mechanical tools to physically adjust or reposition misaligned structural features, the system uses image detection to identify misalignment and modifies the target design digitally. This substitution of mechanical correction with information processing and design modification maintains precision while significantly improving productivity by eliminating time-consuming physical rework operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements feedback by using image detection to capture actual positions of structural features, comparing them against the target design to identify misalignment, and then using this feedback information to modify subsequent target designs. This closed-loop feedback mechanism ensures that compensation is based on actual measured conditions, maintaining manufacturing precision while enabling continuous production without physical rework.

Inventive Principle:
Principle #23Feedback

AI summary

A method of compensating misalignment during manufacturing laminate-type component carriers is disclosed. The method includes detecting an image of a region of interest of a component carrier structure during manufacturing the component carriers based on the component carrier structure, identifying a structural feature in the image of the region of interest showing misalignment with respect to a target design, and at least partially compensating the identified misalignment of the structural feature by modifying the target design of at least one correlated structural feature to be manufactured subsequently, wherein the at least one correlated structural feature is correlated to said structural feature showing misalignment.
