Problems solved by technology

[0006] The disadvantages of the existing technical solutions are: firstly, Au needs to be continuously plated after electroplating Ni, and Au is a precious metal, so the cost is relatively high, so the production cost will be relatively high; secondly, because the precious metal Au is fully plated, the area is very large, res

Embodiment Construction

[0026] In view of the defects of high material cost caused by continuous plating of precious metal gold in the prior art and high labor cost when manually oiling the solder leg, in the embodiment of the present invention, the structure of the metal leakage terminal is redesigned and a different process is adopted Process production, specifically, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] refer to figure 2 As shown, in the embodiment of the present invention, the detailed process of manufacturing the metal leakage terminal is as follows:

[0028] Step 200: Continuous electroplating of common Ni on the metal alloy.

[0029] In the embodiment of the present invention, preferably, the metal alloy may be Cu alloy.

[0030] Step 210 : plating Au on the functional area of ​​the Ni-plated metal alloy surface, and plating Tin (tin) on the solder leg area.

[0031] In the embodiment of...

Abstract

The invention discloses a production method and products of metal exposed terminals. The production method includes: making the metal exposed terminals by new manufacturing process, namely plating a functional area of metal alloy with Au, plating a weld leg area with metal for enhancing solderability. In other words, the metal for enhancing solderability replaces part of plated Au, and a layer of black Ni is plated on the surface of the metal alloy plated with the Au and the metal for enhancing solderability by rack plating. Therefore the function and appearance requirements of the metal exposed terminals are met, production efficiency of the metal exposed terminals is improved, the cost is lowered, and benefit is created. According to related production and applications, the treatment cost of the metal exposed terminals can be reduced by about 50% by improving the production efficiency and saving precious metals.

Description

technical field [0001] The invention relates to the technical field of electronic production, in particular to a production method of a metal leakage terminal and a product thereof. Background technique [0002] With the increasing aesthetic requirements for the appearance of mobile phones, the color of the metal leakage terminal is required to be consistent with the color of the mobile phone casing, and the color of the casing of the mobile phone is currently mainly black, so the surface treatment of the leakage terminal of the mobile phone is also required to be Black, but at the same time, as a functional leakage terminal, the metal leakage terminal must meet two conditions. First, the welding part of the metal leakage terminal must have weldability; secondly, the functional area of ​​the metal leakage terminal must have enough good contact performance and corrosion resistance. [0003] The mass production process of existing metal leakage terminals is as follows: [00...
