Abstract

The invention discloses the tinned method of a kind of acidity, the component of the tin plating solution that it uses is: stannous sulfate 30~50g/l, sulfuric acid 140~200g/l, Vanadium Pentoxide in FLAKES 0.1~4g/l, benzylideneacetone 0.2~1.8g/l, formaldehyde 2~2ml/l, emulsifying agent 10~20g/l.The tin coating that adopts this tin plating solution to plate out has advantages such as good weldability, light, good stability, can be widely used in electrician and the electronic devices and components.

Description

The tinned method of a kind of acidity
The present invention relates to electric plating method, more particularly, the present invention relates to acid tinned method.
In recent years, along with developing rapidly of electronic industry, for the weldability of improving electronic devices and components and reduce cost, people attempt to plate the tin coating of good weldability on the lead-in wire of electronic devices and components.China China Machine Press 1989 publish " the electroplating technology handbook discloses the tinned method of a kind of acidity (seeing the 144th page of this book).This method adopts the plating bath of following component:
Stannous sulfate 35~48g/L, sulfuric acid 60~100g/L, phenol sulfonic acid 80~100g/L, phenol 6~10g/L, formaldehyde 0.5~1g/L, gelatin 2~3g/L, beta naphthal 0.5~1g/L.
Use the plating bath of this prescription to electroplate, although can obtain the coating of light on the plating piece surface, the weldability of coating is poor, and plating piece deposits 2~6 months in air after, coating just becomes grey black, and welding property is poorer.In addition, plating bath itself is also very unstable, places in air 1~2 month, and it is muddy that plating bath just becomes, and has a strong impact on the light and the weldability of coating.
The objective of the invention is to overcome shortcoming of the prior art, a kind of acid tin plating solution of stable performance is provided, adopt the tin coating of this formulations prepared from solutions to have good light, weldability and stability, and with low cost.
The present invention adopts the acid tin plating solution of following component:
Stannous sulfate 30~50g/L
Sulfuric acid 140~200g/L
Vanadium Pentoxide in FLAKES 0.1~4g/L
Benzylideneacetone 0.2~1.8g/L
Formaldehyde 2~20ml/L
Emulsifying agent 10~20g/L
The invention will be further described below by example.Wherein example 1 is a prior art, and remaining example is a content of the present invention.
Example 1:
Stannous sulfate 45g/L, sulfuric acid 100g/L, phenol sulfonic acid 85g/L, phenol 8g/L, formaldehyde 1g/L, gelatin 3g/L, beta naphthal 0.5g/L, 20 ℃ of temperature, current density 1A/dm 2
Example 2~example 5
Figure 941028429_IMG1
The salient features of the tin coating that above-mentioned each example plates out (copper cash with diameter 0.7mm is an example) is shown in the following table.
Figure 941028429_IMG2
As can be seen from the table, adopt the tin coating of the inventive method preparation compared with prior art to have the following advantages: the solderability of coating (wetting power) is good, zero friendship time is short, the coating brightness is good, coating is deposited after half a year still very bright in air, and its good solderability does not change.
