Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electroless plating process is lengthy and costly due to the need for sensitization and activation treatments to facilitate catalyst adhesion on the surface of the object to be plated.
Innovation Solution
A plasma treatment process is used to ionize the surface of the object to be plated, eliminating the need for catalyst activation and simplifying the process by directly immersing the object in a chemical plating solution to form a plating layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensitization and activation treatments are performed on the surface of the object to be plated, then the catalyst can adhere to the surface and facilitate metal deposition, but the overall process becomes long and costly
Solution Approach 1:
The patent changes the surface treatment parameter from chemical sensitization and activation processes to plasma treatment. By using plasma to modify the surface properties of the object, the process achieves catalyst adhesion without requiring the traditional multi-step chemical treatment, thereby reducing process time while maintaining reliability
Solution Approach 2:
The patent replaces the chemical mechanism of sensitization and activation with a physical plasma treatment process. Plasma treatment uses ionized gas to modify the surface, eliminating the need for complex chemical solution treatments and reducing the overall process steps
2Reliability
If sensitization and activation treatments are performed on the surface of the object to be plated, then the catalyst can adhere to the surface and facilitate metal deposition, but the manufacturing cost increases
Solution Approach 1:
The patent changes the surface treatment approach from multiple chemical processing steps to a single plasma treatment step. This parameter change reduces the number of materials, chemicals, and process steps required, thereby lowering manufacturing costs while maintaining the reliability of catalyst adhesion
Solution Approach 2:
The patent extracts and eliminates the unnecessary sensitization and activation treatment steps from the traditional electroless plating process. By removing these redundant steps and replacing them with plasma treatment, the process achieves the same catalyst adhesion function with fewer steps and lower cost
3Manufacturing precision
If traditional electroless plating process is used, then metal deposition can be achieved, but the process is lengthy and costly due to multiple treatment steps
Solution Approach 1:
The patent replaces the traditional chemical sensitization and activation sequence with a plasma treatment step. This substitution maintains the quality of metal deposition while significantly improving process efficiency by reducing the number of steps and time required
Solution Approach 2:
The patent merges the surface preparation and activation functions into a single plasma treatment step. By combining what were previously separate sensitization and activation processes into one integrated step, the patent improves productivity without compromising plating quality
