本発明は半田コテ先に係り、特に寸法精度が著しく改善
された半田コテ先に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Industry A] The present invention relates to a soldering iron tip, and particularly to a soldering iron tip with significantly improved dimensional accuracy.
［従来の技術］

１ｍｍ厚さの鉄（純鉄）メツキが施されている。The main body of a conventional soldering iron tip is made of copper (oxygen-free copper) in view of the thermal conductivity of the heater. In order to ensure wettability with solder, to prevent copper from melting due to the formation of an alloy between solder and copper, and to prevent material deterioration due to high-temperature oxidation of copper, the tip is 0.5～
It is plated with 1mm thick iron (pure iron).

けを正確に行なうことができないという欠点があった。[Problems to be Solved by the Invention] However, with conventional soldering iron tips that are made of iron plating on the surface of a copper base, it is not possible to manufacture sufficiently thin tips with high dimensional accuracy. This is because the solder gets wet in the soldered area, and the soldered area tends to become larger as the iron plating wears out. For this reason,
Conventional soldering iron tips have a drawback in that they cannot accurately solder minute and complicated parts to be soldered.
本発明は上記従来の問題点を解決し、細い半田コテ先で
あっても寸法精度良く製作することが可能な半田コテ先
を提供することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a soldering iron tip that can be manufactured with high dimensional accuracy even if it is a thin soldering iron tip.

精度良く製作することができる。[Operation] An amorphous alloy or ceramic coating film can be formed easily and with high precision by a physical vapor deposition method such as a sputtering method or a chemical vapor deposition method such as a CVD method. Therefore, the soldering iron tip of the present invention can be manufactured with high dimensional accuracy even if it is thin.

化させることにより精密な高精度の半田付けを行なう。The coating film formed on the soldering iron tip of the present invention is an amorphous alloy or ceramic to which solder does not easily adhere. That is, the soldering iron tip of the present invention is of a type that is used only for heating and melting solder, and when using it, solder such as cream solder is applied to the part to be soldered in advance, and solder such as cream solder is applied beforehand. Cream solder or the like on the solder portion is locally melted using the soldering iron tip of the present invention, and then left to cool and harden, thereby achieving precise and high-precision soldering.

も向上できる。If a soldering iron tip is coated with an amorphous alloy or ceramic coating film to which it is difficult for solder to adhere, the solder will not get onto the soldering iron tip, and the solder application area will be disturbed by the soldering iron tip. Moreover, since the shape of the soldering iron tip does not change over time, even minute parts to be soldered can be soldered with high precision, and the durability of the soldering iron tip can be improved.
