Abstract

The invention discloses a gold plated layer pore detection method on a silver-magnesium-nickel material. After being soaked by a sodium sulphide solution, a gold plated part of the silver-magnesium-nickel material is taken out to be cleaned and is put into the air to perform still standing for 10 to 20min; then, drying and observation are performed; next, visual checking or observation under a microscope being 20 to 30 times is performed. During the process detection, the judging errors are small. The process is simple; the part plating quality guarantee performance is high; the production site control is easy.

Description

Gold plated Layer hole detection method on a kind of silver-colored magnesium nickel material
Technical field
The present invention relates to Gold plated Layer hole detection method on a kind of silver-colored magnesium nickel material, the little silver of particularly a kind of decision errors Gold plated Layer hole detection method on magnesium nickel material.
Background technology
The development advanced by leaps and bounds with the information age, electronic component products volume of production are continued to increase.As electronic component The craft of gilding quality of core process technology, is increasingly taken seriously.Gold-plated quality is directly connected to the matter of electronic product Amount ensures which directly affects the reliability and stability of product.Class silver magnesium nickel material plating used in as electronic devices and components Gold, the porosity of its coating have a strong impact on the functional characteristic of product.As contact resistance is big, often change colour etc..Therefore, quality assurance Porosity detection is most important.
At present, the detection method without silver-colored magnesium nickel material gold-plating layer porosity, conventional is contrast reference.Often plated with iron material nickel plating Gold, then with the potassium ferricyanide or potassium ferrocyanide mounting method detecting porosity, due to potassium ferrocyanide and the characteristic reaction of silver Sensitivity is poor, is often compared detection with the gold-plated coating of iron-based nickel plating to its corresponding plated thickness detection porosity.Often Method presses JB2112-77《The metal cladding porosity method of inspection, moistening reagent paper post method》, standard sample nickel plating is gold-plated (With Gold plated Layer on silver-colored magnesium nickel material in same thickness range)Afterwards, potassium ferrocyanide solution is stained with reagent paper, be pasted on standard sample, Repeatedly, then examine under a microscope coating surface hot spot, it was demonstrated that the presence of porosity.So detection occurs sentencing often Determine error big, part quality of coating protection is low.And necessary professional's operation, it is poor that production scene controls.
The content of the invention
It is an object of the present invention to provide Gold plated Layer hole detection method on a kind of silver-colored magnesium nickel material, present invention process inspection During survey, decision errors are little, process is simple, and part quality of coating protection is high.Production scene is easy to control.
The present invention employs the following technical solutions realization:
Gold plated Layer hole detection method on a kind of silver-colored magnesium nickel material, the plating metal parts Jing sodium sulfide solutions of silver-colored magnesium nickel material are soaked Afterwards, take out cleaning, in air it is quiet put 10-20min after, be dried, observation, then visually or in 20-30 times of basis of microscopic observation, .
Gold plated Layer hole detection method on aforesaid silver-colored magnesium nickel material, the sodium sulfide solution are so prepared:Go by every 1L Ionized water adds 50g sodium sulfide, stirs, obtains final product.
Gold plated Layer hole detection method on aforesaid silver-colored magnesium nickel material, in immersion process, sodium sulfide solution temperature is 15-35 ℃。
Gold plated Layer hole detection method on aforesaid silver-colored magnesium nickel material, sodium sulfide solution soak time are 5-20min.
With prior art ratio, the inventive method has the advantages that:
1st, during present invention detection, directly detected with part, i.e., directly part is placed in sodium sulfide solution and is soaked, Ran Houjing Put, clean, being dried, then examining under a microscope corrosion of coating point.Therefore, the method operation is improved than mounting method operating efficiency More than 10 times, and it is easy, therefore be easily applied to produce control.
, the inventive method decision errors it is little, applicant takes same batch qualified parts sample respectively, uses potassium ferrocyanide respectively Being detected with the inventive method, in 100 times of basis of microscopic observation, as a result seen Fig. 1 and Fig. 2. Fig. 1 is potassium ferrocyanide detection When observe result figure, Fig. 2 is to observe result figure when the inventive method is detected.Subsequently, applicant randomly selects 3 aforementioned ferrous irons Potassium cyanide is detected as qualified part, observes, as a result see Fig. 3, Fig. 4 and Fig. 5 under Electronic Speculum under amplifying 1000 times, as seen from the figure, Space is clearly present.Applicant randomly selects 3 aforementioned the inventive method and is detected as qualified part simultaneously, transfers in Electronic Speculum Observe under big 1000 times, as a result see Fig. 6, Fig. 7 and Fig. 8, as seen from the figure, tight is present.It follows that detection method It is less than existing detection method decision errors.
, this method cancel comparison and detection decision method, directly detected with electroplated component, and detected there is easy, field Ground is less demanding, only needs beaker and microscope, and operator's skill set requirements are low, easily realize production scene control, it is ensured that coating matter The concordance and stability of amount.And existing application technology, need calibrated bolck, reagent paper, beaker, reagent paper stickup to require smooth(Must not It is crooked, not so paste deficiency of time), paste bubble-free etc..
