題がある。[Prior art] Conventionally, solder plating is used as an inexpensive lead wire material for electronic components using iron wire, in which nickel plating is applied as a base plating on the iron wire, and then solder (or tin) plating is applied on top of the nickel plating. Iron wire is known, but solder (or tin)-plated iron wire with nickel plating as the base plating originally has poor solderability due to the nature of nickel plating, so the thickness of the solder plating is not too thin. There are problems in that it is impossible to do so, and there are concerns about soldering reliability at high temperatures.

田めつきの厚さを厚くすることにより解決できる
ことであるが、その代わり製品の価格が高くなる
ことになる。 In other words, if the thickness of the solder plating is reduced beyond a certain level, the nickel plating as the base plating will be exposed during soldering, and the solder may be repelled by this nickel plating, making it impossible to perform the soldering work. There is a problem. Of course, this problem can be solved by increasing the thickness of the solder plating, but at the cost of increasing the price of the product.
一方、構造材料としての銅・亜鉛合金は従来か

例はこれまでにない。 On the other hand, copper-zinc alloys have long been known as structural materials, but copper-zinc alloys have not been used or considered in the field of lead wires for electronic components, and moreover, as base plating materials for solder-plated iron wires. There has never been an example of this.

An object of the present invention is to provide an inexpensive and advantageous copper-zinc alloy base solder-plated iron wire that can be made thin.

As a result, the overall thickness of the solder plating can be reduced.

Zinc alloy plating is applied, but the thickness is 0.3μ ~
It is preferably 0.5μ (preferably 0.4μ).
The thickness of the solder plating (or tin plating) is preferably 4.0μ to 7μ. The necessary solderability can be obtained if the ratio of copper and zinc in the copper-zinc alloy is 90% to 50% copper and 10% to 50% zinc. That is, 95%
It satisfies the MIL standard with the above solder wetted area.
