Description
Technical field
The present invention relates to a kind of electronic devices and components and manufacture method.Be specifically related to a kind of high-voltage thin-film capacitor and manufacture method of thoughts cascaded structure.
Background technology
From film capacitor analysis that is international and domestic market sales, can apply under high pressure occasion, the miniaturized capacitance device of high power capacity precision is that following miniwatt energy-saving lamp is first-selected, but only have CBB81 structure and CL11 thoughts type capacitor to reach requirement as start-up capacitance, but CL11 is foil electrode structure, do not have self-healing feature, high pressure resistant reliability is low; And be single electric capacity, withstand voltage lifting has very large restriction.CBB81 structure can meet the demands, but the utilance of electrode is low, complex process, and cost is high, and metal spraying welding is drawn again very large pollution, and it is long to go out delivery date, can not meet the demand of present client.From situation that is international, domestic development.The requirement of the reliability of electricity-saving lamp is more and more higher, more and more lower to the price request of product, therefore to reliability and the cost proposition requirements at the higher level of electronic product.
Traditional CBB81 type capacitor arrangement is (in figure: lead-in wire A1, electrode A 2, medium A 4, gilding layer A5) as shown in Figure 1, and traditional technological process is: 1: winding, and by film, aluminium foil is formed by sutomatic winding machine winding; 2: hot pressing, capacitor core bag pressure is flat, and get rid of gas, capacitor core bag is qualitative; 3: bag paper (mask), be aided process, for metal spraying is prepared; 4: metal spraying, capacitor core bag two ends metal layer spraying; 5: energize, remove the weak link of the capacitor such as fault, metal spraying connection; 6: welding, the gilding layer at capacitor two ends welds CP line extraction electrode; 7: compile platform, by welded capacitor neat be organized on platen; 8: encapsulating, print, test.Said method technique is loaded down with trivial details, needs more equipment and man-hour, has metal spraying operation, and have certain metallic pollution, production cost is high, and the production cycle is long.Above-mentioned capacitor is welding lead on gilding layer in addition, there is complex procedures, metal spraying process exists the problem polluted; Effective width=electrode width-aluminium foil overhang-the metal film of above-mentioned electrode for capacitors stays limit to measure, causes electrode width narrow like this.
Summary of the invention
The object of this invention is to provide a kind of high-voltage film capacitor with inductive series structure and manufacture method, the invention solves existing miniwatt energy-saving lamp start-up capacitance complex procedures, metal spraying process exist pollute, problem that electrode width is narrow etc.
High-voltage film capacitor with inductive series structure of the present invention, is made up of lead-in wire 1, capacitor body 2 and body 3; It is inner that capacitor body 2 is arranged at body 3; Described capacitor body 2 comprises dielectric layer 4, metallized film 5 and electrode 6, three layers of dielectric layer 4 are had to stack each other, an electrode 6 is respectively arranged with between every two layer medium layer 4, the lateral surface of the dielectric layer 4 in an outside has metallized film 5, with metallized film 5 for dielectric layer 4, metallized film 5 and electrode 6 winding is formed capacitor body 2 by outermost; Two inner connecting electrodes 6 respectively of lead-in wire 1,1 outer end that goes between causes outside body 3.
The manufacture method of high-voltage film capacitor with inductive series structure of the present invention, operates in accordance with the following steps:
(1) reel, three layers of dielectric layer 4 are stacked each other, an electrode 6 is placed between every two layer medium layer 4, the lateral surface of the dielectric layer 4 in an outside arranges metallized film 5, with metallized film 5 for dielectric layer 4, metallized film 5 and electrode 6 reel and make capacitor body 2 by outermost; Lead-in wire 1 welding electrode 6 will be drawn in winding process;
(2) compile platform, by welded capacitor neat be organized on platen;
(3) hot pressing, capacitor core bag pressure is flat, and get rid of gas, capacitor core bag is qualitative;
(4) encapsulate, print, test.
Capacitor high-frequency loss of the present invention is little, and self heats up little, and temperature capacity is strong, and dielectric behavior is stablized, and also must have stronger moisture protection and resisting temperature impact capacity, and pin, apart from easy for installation flexibly, can normally work again for a long time under 100 DEG C of-110 DEG C of operational environments.This kind of capacitor small size, cost are low, highly reliable, safety and environmental protection, can apply under the occasion of high pressure, big current.
The present invention is compared with the prior art: 1: lead-out wire is different: prior art is that metal spraying welding is drawn, and the present invention is that wire bonds is drawn on electrode, reduces operation, does not have metal spraying, does not pollute.2: the effective rate of utilization of electrode is different: the effective width=electrode width-aluminium foil overhang-metal film of prior art electrode stays limit to measure, the effective width=electrode width of electrode of the present invention.
