Background technology
Along with the cost degradation of the miniaturization of electronic product and the appearance of all kinds of high-clear displays and LED illuminating productUniversal, existing inductance component has been had to higher requirement, both require the miniaturization of inductance component size, its electric currentAbility is constant. And need to there is function of shielding to reduce the electromagnetic field producing while work because of this inductance component to otherThe interference of element. Colour loop inductance device imports inland of China into more than 20 year from the latter stage eighties, and development rapidly, existingChinese festiva output has reached 7,000,000,000, taking 0307 product as example, unit price from initial 1992 0.25 yuan to existing0.025 yuan, unit price lattice just decline 10 times, main cause is making of automatic coil winding machine, full-automatic pin connecting machineWith, cost is significantly declined. A full-automatic colour loop inductance production line of present stage investment, with monthly shipment 500Ten thousand is example, and equipment investment, up to 1,300,000 yuans, is calculated with the net profits of annual 200000 yuan, needs6 years above time could be regained equipment investment, and this does not wherein also have the accessory loss maintenance cost of computing equipment,Therefore greatly increased investment risk. Secondly along with the miniaturization of electronic product, the automated production of chip inductor becomesThis also declines to a great extent. Along with the cost of High-Speed Automatic coil winding machine and high-speed full-automatic point gum machine declines to a great extent, cause magneticThe price of glue protected type paster power inductance also declines to a great extent, and inductance has the feature of closed magnetic circuit, has greatly replacementThe trend of colour loop inductance. The function singleness of colour loop inductance for a long time, although price is cheap, without revolutionaryTechnology occurs. Chinese Patent Application No. is: in 200910041053.7 patent, introduce one and can reduce colour circle electricityThe coating process of the pore (pin hole) of sense, but use this patent to be coated with the colour loop inductance device taking on, can only be at poreOn reduce to some extent or stop. The function of colour loop inductance device is without any change. And there is pin hole at application colour loop inductanceProblem on, exceed 5 years above application techniques people along with the continuous lifting of UV coating technology and for oneMember does not have technical difficulty, can make equally colour loop inductance not produce in coating process without the method for this patentPin hole, this is also one of reason causing the price continuous decrease of colour loop inductance device.

Further again, the length of described the second～five road coating baking box is 3-6 rice, and wherein every one coating baking box hasTwo independent baking boxs of 1.5-3 rice connect to form.
Utilize technique of the present invention, can manufacture low inductance value protected type hyperfrequency colour loop inductance device, use knownCeramic process manufacture method is made ' work ' type colour loop inductance core of white, and this core is for first using alumina powder,Zirconia, aluminium nitride etc. are any one material wherein, processes ' work ' type look obtaining with known production method manufactureRing inductance pottery core, according to the coiling of protected type colour loop inductance manufacturing process and application, makes protected type superelevation thereafterFrequently colour loop inductance device. This hyperfrequency colour loop inductance device utilizes the high frequency spy of the pottery such as aluminium oxide or aluminium nitride, zirconiaProperty and without permeability and low-expansion coefficient, makes lower than the colour loop inductance device below 1UH the electricity of this inductorSense value is leaned on the self-induction of the copper cash number of turns completely. Inductance value changes little, agrees to control with respect to FERRITE CORE. SizeCan be from 0307 (1/4W) to 0515 (2W) without electromagnetic interference.
Compared with prior art, advantage of the present invention:
1. owing to using former colour loop inductance to paint as coating, still in coating, added soft magnetic ferrite magnetic,Can effectively shield the interference to other parts of leakage field that colour loop inductance device produces at work.
2. in colour loop inductance coating, add magnetic, can significantly reduce coating cost, with colour circle electricity in the marketIt is example that the price of sense paint is 37 yuan/kilogram, is adding after curing agent than row with 1: 0.4. After mixing and stirringInductance paint by adding magnetic at 1: 1.5. Described magnetic is taking manganese-zinc ferrite magnetic as example, manganese-zinc ferrite magneticPowder, for switching mode power supply transformer grinds the accessory that produces of air gap, is worth about 500-1200 yuan/ton, dry andAgain the processing cost shattering is at 300-500 yuan/ton, and processing magnetic price later, at 2000 yuan/ton, is changed like thisAfter calculation greatly about 2 yuan/kilogram. Taking aforementioned proportion 1: 1.5 as example, namely 2 kilograms of conventional inductance paint are converted 3 public affairsJin magnetic, mixed shielding inductance coating is 5 kilograms, cost is 80 yuan, amounts to per kilogram shielding inductance and is coated withMaterial is 16 yuans, coating cost 50%.
3. owing to adding a large amount of magnetics in protected type colour loop inductance device coating, its inductance value is promoted, inductance value is carriedRise how many relevant with the consumption of magnetic. Inductance value promotes higher, same inductance value, protected type colour loop inductance aroundCoil number obviously will be less than the winding turns of conventional colour loop inductance device, and at this moment copper cash consumption is also than traditional colour circle inductorConsumption reduces, and has reduced copper cash cost.
4. the minimizing of the protected type colour loop inductance device number of turns, can reduce the coil number of plies, and its distribution capacity is reduced,Improve self-resonance frequence.
5. due to protected type colour loop inductance device, use very trickle magnetic powder particle, utilizing coating machine to carry out certainlyIn movingization coating process, can be fine, the well-proportioned magnetic core surface that covers, forms screen layer. Inductor is logicalIn electricity work, the magnetic field intensity of inductor itself increases, and has increased anti-saturation. Through overtesting and test, evenlyMagnetic field intensity bring highly stable Q (quality factor) value, make the uniformity of Q value fine.
6. use the coating process of describing in the present invention, on the groove that is coated with shielding paint, side installs little merit additionalRate deceleration stirring motor can effectively solve the sedimentation problem of magnetic in coating.
7. can realize with the shielding colour loop inductance device of ceramic core coiling high-power, low inductance value, I is accomplished1NH, simultaneously self-resonance frequence can arrive 5-10GHz, and this is military or meaning weight above civilian communications equipment at hyperfrequencyGreatly. This is that traditional colour circle inductor current, FERRITE CORE are not accomplished. Secondly contrast and pottery coiling pasterInductance, due to conventional pottery coiling chip inductor, ceramic volumetric is little, has so also limited diameter and the electricity of copper cashThe size of stream, has limited power equally, and the protected type colour loop inductance device of ceramic core coiling, due to ceramic coreVolume strengthen, the wire diameter of copper cash and electric current also significantly promote, simultaneously power also significantly promotes, and in shielding coating, containsThere is magnetic, can shield the interference to other parts of leakage field in inductance work; This effect in communication signal circuitObviously.
The present invention is mainly applicable to optimization and the improvement to colour loop inductance.
