Description
Technical field
The present invention relates to a kind of inductance elements of the molding coil-conductor of conduction material, can espespecially reduce the inductance of whole height
Element, lie in insulation rubber base be equipped with U-shape positioning region, and in each positioning region surface using laser activation with change plating conduction material at
Type is conductor, installs magnetic conductive component in insulation rubber base, and each conductor is electrically connected with lane array on carrier is connect, with
Magnetic conductive component of arranging in pairs or groups forms the wire loop of magnetic strength effect.
Background technique
With electronic technology Fast Growth, active member and quilt are arrived so that can all use on circuit board inside electronic product
Dynamic element, wherein operation, processing function can be individually performed in active member (such as microprocessor or chip), and passive device is (such as
Resistance, capacitor and inductance etc.) it is then that can make resistance or impedance will not when carrying out current or voltage change relative to active member
The element changed correspondingly, and also must be considered that the circuit characteristic between each element when in use, be collocated with each other be applied to information,
Communication, consumer electronics etc. reach the function of electronic loop control.
Furthermore inductance element can generate electromotive force because passing through the change of electric current in circuit, so that the change of electric current is resisted, electricity
There are many patterns for sensing unit, wherein it is known as coil according to appearance frequently as inductance used in electromagnet and transformer, it can be to high frequency
Biggish resistance is provided, and is then frequently referred to choke coil or choke coil according to function by what direct current or low frequency used, and often cooperate iron
Magnetic material is mounted on larger inductance, also referred to as winding used in transformer, motor and generator, and inductance element
Self-induction and mutual induction can also be divided into according to electromagnetic induction, when conducting wire the number of turns of winding magnetic substance (such as magnetic core or ferrimagnet) increases
When more, the inductance of conductor can also become larger, and be not only the number of turns, area of every circle (loop) etc., conductor material can all influence electricity
Feel size.
And general inductance element is as made by ferromagnetic magnetic core or the core material higher than air permeability, and in outside core material
Portion is wound with a loop coil, can pass through the magnetic flux change generated when electric current by core material cooperation coil, and utilize variation
Magnetic field induction induce electric current, only in practical application, there are still have following many missings for the inductance element:
(1) when the core material of inductance element is externally wrapped with coil, due to artificial winding gimmick and the difference in direction, Chang Huiyin
Difference in coiling distribution causes the situation of coil density unevenness, and be difficult to control the stray capacitance on inductance element will, leads
The difference of noise rejection ability between the coil of same size is caused to increase, and between necessary accurately control coil coiling to each other
Away from, and because of core material small volume, using artificial winding mode, not only whole process quite expends working hour, also can not be in response to processing procedure
Demand mass production reduce manufacturing cost also can not.
(2) inductance element is to acquire biggish inductance, generally coil-winding can be overlapped, so in artificial coiling
It is easy to scratch the insulating layer of enameled wire in the process, and after core material is externally wrapped with coil, will also result in core material volume becomes larger, and will
It is occupied to be welded in biggish space on circuit board and influence integrated circuit layout, and during inductance element welds,
It is easy to touch because volume is larger with other electronic components, causes coil there may be scratching, and then it is first to influence inductance
Part electrical characteristic and charging/discharging function.
Therefore how to solve current inductance element manually the time-consuming of convolute coil, take a lot of work, and can not largely give birth to
It produces, problem and puzzlement at high cost, and inductance element volume is big, occupies space on circuit board, and influences the electrical of inductance element
