Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Imaging devices face issues with thermal deformation of substrates causing optical axis shifts and reduced durability, especially when mounting imaging elements on layered ceramic and organic resin substrates.
Innovation Solution
A dual-substrate configuration with a ceramic-based first substrate and an organic resin-based second substrate, where the imaging element is mounted on the ceramic substrate and the lens holder or window material is installed around the mounting region, reducing positional deviations due to thermal deformation and enhancing durability.

Engineering Contradiction Analysis
1Ease of manufacture
If a layered substrate structure with organic resin is used, then ease of manufacture and weight reduction are improved, but thermal deformation causes optical axis shifts and reduced reliability
Solution Approach 1:
The substrate is divided into two separate layers: a first substrate made of ceramic material and a second substrate made of organic resin material. The imaging element is mounted on the first substrate, which provides thermal stability and prevents deformation, while the second substrate is attached to the back surface to maintain the lightweight and ease of manufacture advantages. This segmentation allows each material to perform its optimal function without compromising the other.
Solution Approach 2:
The invention uses a composite substrate structure combining ceramic material and organic resin material in a layered configuration. The ceramic first substrate provides high thermal stability and dimensional stability to prevent optical axis shifts, while the organic resin second substrate contributes to weight reduction and ease of manufacturing. Together, they create a composite structure that balances thermal performance with manufacturing advantages.

AI summary
The electrical element-mounting substrate includes a first substrate including a ceramic as a first base member, and a second substrate including an organic resin as a second base member. The first substrate has a first surface and a second surface opposite to the first surface. The first surface includes a first mounting region where an electrical element is mounted and an installation portion where a lens holder or a window material is installed. The installation portion is located around the first mounting region in a plan view. The second substrate is located on the second surface of the first substrate.
