Solder tip resistant to oxidation and corrosion under high temperature and production method of solder tip

Abstract

The invention discloses a solder tip resistant to oxidation and corrosion under high temperature and a production method of the solder tip. The solder tip comprises a welding head and a mounting pipe,wherein one end of the mounting pipe is detachably connected with the welding head, the other end of the mounting pipe is connected with a soldering iron core of an external electric soldering iron,the welding head comprises a mounting base and a heating portion arranged on the mounting base, the heating portion is plated with an anti-oxidation layer, the welding head is made of an alloy consisting of nickel, chromium and aluminum, and then the welding head is sequentially placed into electroplating nickel liquid, electroplating aluminum liquid and electroplating chromium liquid at preset temperature, so that the plating work on the anti-oxidation layer is completed. The solder tip has the advantages that the oxidation resistance and corrosion resistance of the produced solder tip are greatly improved under the high temperature, the solder tip is not prone to oxidation, corrosion or perforation, the anti-oxidation layer well protects the solder tip, and the service life is prolongedfor a long time.

Description

technical field [0001] The invention relates to the technical field of soldering iron tip production, in particular to an oxidation-resistant and corrosion-resistant soldering iron tip at high temperature and a manufacturing method thereof. Background technique [0002] The soldering iron tip is the key component of the electric soldering iron or soldering station, and it is an important part that affects the soldering effect and service life. During the soldering operation, the soldering iron tip is in direct contact with the tin material and is always in a high temperature state of 360-420 degrees. At present, the industry generally implements the EU ROHS directive. After the introduction of lead-free solder, the working temperature is as high as 420-480 degrees. Therefore, higher requirements are put forward for the high temperature resistance, oxidation resistance and corrosion resistance of the soldering iron tip. The traditional method of producing soldering iron tips ...

AI Technical Summary

Problems solved by technology

The traditional method of producing soldering iron tips in the industry is that copper rods are machined into copper billets, and then processed into copper substrates, and then undergo a series of electroplating treatments such as iron plating, nickel plating, and chrome plating, and finally make soldering iron tips. Among them, The ratio and thickness of the gold-plated layer will directly affect the quality of the soldering iron tip. If the thickness of the gold-plated layer is not well done, it will cause poor thermal conductivity of the soldering iron tip, poor soldering, and sharp edges, which will lead to false soldering and false soldering. Poor solder joints; if the ratio of the gold-plated layer is not good, it will cause the tip of the soldering iron to oxidize, corrode, and even be scrapped due to perforation and tip breakage during high-temperature work

This production process not only increases the production cost, but at the same time, frequent replacement of soldering iron tips reduces work efficiency, which has become a recognized problem in the industry.
