Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tin methanesulfonate solutions have lower tin ion concentrations, which are insufficient for effective supplementation in tin plating processes.
Innovation Solution
Dissolving tin (II) oxide in an aqueous methanesulfonic acid solution with a specific mole ratio of methanesulfonic acid to tin (II) oxide, where the value of B/2A ranges from 1.0 to 1.4, to produce a solution with a higher tin ion concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If tin (II) oxide is dissolved in aqueous methanesulfonic acid solution using conventional methods, then the solution can be used for tin plating supplementation, but the tin ion concentration remains low and insufficient for effective supplementation
Solution Approach 1:
The patent changes the molar ratio parameter of methanesulfonic acid to tin (II) oxide from conventional values to a specific range of B/2A = 1.0 to 1.4. This parameter optimization enables significantly higher tin ion concentration in the resulting solution, directly resolving the contradiction between quantity of substance and supplementation efficiency
2Productivity
If existing tin methanesulfonate solutions are used, then the plating process can continue, but the low tin ion concentration requires frequent supplementation and reduces process efficiency
Solution Approach 1:
By optimizing the molar ratio parameter B/2A to 1.0-1.4, the patent achieves higher tin ion concentration that directly improves plating process efficiency, reducing the frequency of supplementation operations while maintaining stable plating quality
