Tubular Iron Tip Solder Feeding for Flux-Assisted Melting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a solder piece is heated in an upright posture within an iron tip, the flux with a low melting point tends to flow out from the lower end, reducing heat transmission and preventing effective melting of the solder.
Innovation Solution
A solder processing device with a vertically extendable tubular iron tip and a solder piece supply mechanism that sequentially feeds solder pieces with a flux layer, where the first solder piece is erected and the second solder piece rides on it, ensuring heat is efficiently transferred and the solder is melted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the solder piece is heated in an upright posture within the iron tip, then the flux can flow out from the upper end or side surface to enhance heat transmission, but the flux easily flows out from the lower end causing poor contactability between the inner wall of the iron tip and the solder piece
Solution Approach 1:
The patent inverts the conventional understanding of flux flow direction. Instead of preventing flux from flowing out, the invention allows flux to flow out from the lower end intentionally, and this outward-flowing flux serves as a heat medium to transmit heat from the iron tip to the solder piece, thereby resolving the contradiction between heat transmission and contactability
Solution Approach 2:
The flux that flows out from the lower end of the solder piece acts as an intermediary substance. This flux layer serves dual purposes: it maintains contactability between the iron tip and solder piece while simultaneously functioning as a heat medium to improve heat transmission efficiency
2Temperature
If the flux flows out from the lower end of the solder piece, then it may serve as a heat medium, but the flux flows downward and is unlikely to be interposed between the inner wall of the iron tip and the solder piece
Solution Approach 1:
The patent converts the potentially harmful effect of flux flowing downward into a beneficial effect. By allowing the flux to flow out from the lower end, the invention utilizes this outward flow to create a flux layer that acts as an effective heat medium, transforming what could be a contactability problem into a heat transmission advantage

AI summary
A solder processing method according to one or more embodiments may include: sequentially supplying at least two solder pieces into a substantially tubular iron tip that is extended vertically, such that the at least two solder pieces are erected within the iron tip in such a manner that on the solder piece which is first supplied, the solder piece which is subsequently supplied rides; and heating the substantially tubular iron tip in a state where the at least two solder pieces are erected within the iron tip in such a manner that on the solder piece which is first supplied, the solder piece which is subsequently supplied rides, to melt the flux to be flown out from at least one of the at least two solder pieces to a space between an inner wall of the iron tip and the at least two solder pieces.
