Description
Technical field
This utility model relates to electronic component technology field, especially relates to a kind of metal dust matrix inducer
Electrode.
Background technology
Inducer (Inductor) is the element that electric energy can be converted into magnetic energy and store.The knot of inducer
Structure is similar to transformator, but only one of which winding.Inducer has certain inductance, and it only hinders electric current
Change.If inducer is not when having electric current to pass through, during circuit ON, it will attempt to hinder electric current stream
Cross it；If inducer is when there being electric current to pass through, when circuit disconnects, it will attempt to maintain electric current constant.
In recent years, electronics field develops rapidly, and circuit board, if PCB is the necessary portion of electronic product
Part, and on pcb board, inducer is the electronic component that utilization rate is the highest.
Two electrodes of traditional inducer, are to use following method to prepare: first at the electrode of inducer
Place's coating conductive silver paste, then forms through high temperature sintering, hereafter, forms nickel dam and tin layers on silver layer.But
It is that in the termination electrode manufacture process of current inducer, main use silver slurry is as hearth electrode materials'use, passes through
Being the fine silver of more than 90% after binder removal, but be as economy in recent years and develop rapidly, the prices of raw materials go up
Very big, the particularly rise in price of silver slurry is swifter and more violent, is affected by silver slurry price rising, causes inducer raw
Product cost increases considerably, the great difficulty to production and operation band.
On the other hand, in recent years, metal dust matrix (ferrum, nickel, chromium, aluminum etc.) inducer substitutes gradually
Traditional ferrum epoxide inducer, and the most easy-tolerated high temperature of metal dust matrix inducer, if using above-mentioned
Method prepares its electrode, when conductive silver paste is carried out high temperature sintering, can damage described inductor body.Cause
This, said method is not suitable for metal dust matrix inducer yet.
Utility model content
For solving prior art shortcomings and deficiencies, the purpose of this utility model is to provide a kind of metal dust matrix
The electrode of inducer.
The purpose of this utility model is achieved through the following technical solutions:
The electrode of a kind of metal dust matrix inducer, it is arranged at the electrode of described inducer, described electricity
Pole includes basic unit, conductive layer and the tin layers stacked gradually at described electrode, and described basic unit is by plating
Mode is arranged at described electrode.
Preferably, described basic unit includes one layer of conductive metal layer.
Preferably, described conductive layer includes one layer of conductive metal layer or electrical conductivity alloy layer, or is cascading
Multilayer conductive metal level and/or electrical conductivity alloy layer.
Preferably, described basic unit is: zinc, copper, nickel or silver；Described conductive metal layer is: copper, nickel or silver；
Described electrical conductivity alloy layer is: nichrome or signal bronze.
Relative to prior art, the utility model has the advantage of:
1, by reducing the energy consumption using and reducing in technique of noble metal, existing electrode process is greatly lowered
The cost of preparation；
2, improve electrode adhesion, strengthen its installation reliability；
3, simplify preparation technology, improve the yields in batch production；
4, improve metal dust matrix resistance to corrosion, extend the service life of device.
