Molten Solder Agitation Path for Faster Dross Decomposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soldering apparatuses face limitations in effectively decomposing dross, which is an oxide formed during the oxidation of molten solder.
Innovation Solution
A solder process apparatus with an extension part that reciprocates horizontally in the molten solder while changing its vertical position, accompanied by a partition part to block dross movement, enhancing decomposition efficiency.

Engineering Contradiction Analysis
1Productivity
If a large number of vanes are installed on a shaft to decompose dross, then dross decomposition is achieved at a certain level, but the device complexity increases and decomposition effectiveness is limited
Solution Approach 1:
The extension part is designed to reciprocate horizontally while changing its vertical position, transforming a static structure into a dynamic one. This dynamic movement creates more effective fluid disturbance and dross decomposition compared to static vanes, while using a simpler single moving component instead of multiple vanes on a shaft
Solution Approach 2:
The extension part moves not only horizontally but also changes its vertical position, adding a vertical dimension to the horizontal reciprocating motion. This two-dimensional movement pattern enhances dross decomposition effectiveness by creating more varied fluid disturbance patterns compared to simple horizontal or vertical movements alone
2Productivity
If the extension part reciprocates horizontally in the molten solder, then dross decomposition is accelerated, but dross may reach the supply unit
Solution Approach 1:
The storage tank is divided into two regions by the partition part: a movement region where the extension part reciprocates to decompose dross, and a supply region where the supply unit is located. The partition part acts as a barrier that segments the tank to prevent dross from reaching the supply unit while allowing the extension part to operate effectively in the movement region
Solution Approach 2:
The partition part serves as an intermediary barrier between the dross decomposition zone and the supply unit. It allows the decomposition process to proceed vigorously in the movement region while blocking the path of dross toward the supply unit, thus protecting the supply unit without interfering with the decomposition process
