Dual-Sided Holding Device for Simultaneous Galvanic Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for galvanically treating planar products, such as wafers or printed circuit boards, often require sequential coating of both sides, which is inefficient and lacks automation, and there is a need for devices that can simultaneously coat both sides while maintaining a sealed environment to prevent fluid penetration.
Innovation Solution
A holding device comprising a first and second holding part with electrical contact elements for both sides of the product, which can be fastened together in a detachable manner to hold the product securely and maintain a seal, allowing for simultaneous galvanic treatment of both sides, with options for mechanical, vacuum, or magnetic locking mechanisms to secure the parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequential coating is used for both sides of the product, then the treatment process is simpler to implement, but the productivity is reduced due to longer processing time
Solution Approach 1:
The holding device is divided into a first holding part and a second holding part that can be detached from each other. Each holding part has electrical contact elements for contacting one side of the product. This segmentation allows the product to be treated on both sides simultaneously by placing it between the two holding parts, thereby improving productivity while maintaining manageable device complexity through modular design.
2Productivity
If both sides of the product are contacted simultaneously, then the productivity is improved, but the reliability deteriorates due to risk of fluid penetration into electrical contact elements
Solution Approach 1:
The holding parts are designed with detachable connection that allows them to be separated from each other. This dimensional change in the structure enables the electrical contact elements to be positioned in a way that they contact the product sides simultaneously while being protected from fluid penetration through the detachable connection design that allows proper sealing and positioning.
3Ease of operation
If the holding device is made detachable for easy operation, then the ease of operation is improved, but the reliability worsens due to potential misalignment or loose connection
Solution Approach 1:
The detachable connection between the first and second holding parts is designed to provide both ease of operation and reliable connection. The mechanical design allows for simple fastening and releasing operations while maintaining stable connection during the galvanic treatment process, balancing ease of operation with connection reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
