Description
Technical field
The present invention relates to thin film capacitor manufacturing metallized film materials, more particularly to simultaneously structure is golden in one kind
Categoryization film.
Background technology
For thin film capacitor because it is used widely with good resistance to pressure and self-healing property, metallized film is thin-film electro
The important materials of container production manufacture, by high purity metal（Such as AL, ZN）It melts, evaporate under high vacuum state, being deposited to Jie
On matter basement membrane, the film after medium membrane surface forms one layer of very thin coat of metal is exactly metallized film；It metallizes thin
The resistance value of the unit square area of the coat of metal on film is known as sheet resistance（That is square resistance is indicated with Ω/）, this use
The capacitor that metallized film is manufactured, (i.e. medium basement membrane part is weak if any electricity for the self-healing of pressure-resistant performance and the coat of metal
When point breakdown, disruptive discharge electric current can evaporate the coat of metal ablation around the point, make electric weakness and integral capacitor device pole plate
Form isolation) ability correlation；When the thin film capacitor that common structural metals film is manufactured works under alternating voltage,
The current direction of charge and discharge is to stay avris to flow from gilding layer side to blank, when the thickening side of somewhere layer electrodes and connecing for metal spraying
When touching connection reduction, larger contact resistance can generate heat, or in the case where localized corona electric discharge occurs for capacitor-end somewhere,
Or capacitor by greater impact electric current when, so that the contact connectio of thickening side and metal spraying is completely disengaged, damage area in work electricity
The flow direction of stream just changes its course transfer as fore-and-aft tilt, the contact connectio on still unspoiled the thickening side and metal spraying of flow direction damage area both sides
Area makes damage area extend and enter to both sides to increase and damage the current density and Wen Sheng that area's adjacent connects
Vicious circle.
Invention content
The purpose of the present invention is being directed to the deficiencies in the prior art, provide in one kind and structured metallization film, it can
Damage area's electric current vertical transfer is blocked, so that damage is placed restrictions between two adjacent electrode plate units, makes the impact resistance of capacitor
Electric current and working life improve.
Technical solution：
To achieve the above object, present invention employs following technical schemes：Simultaneously structured metallization film, including basement membrane in a kind of,
It is vaporized on the coating thickener belt of basement membrane vapor deposition face longitudinal central axis, the effect of the coating thickener belt is that process is cut along coating in lower road
The heavy-edge metalized film of coating is formd after the axis cutting of thickener belt, is wound when double-layer metallization film layer is folded misalignment
After capacitor, capacitor body both ends gilding layer adhesive force can be increased；It is symmetrically distributed in continuous point of coating thickener belt both sides
The electrode plate unit of cloth, the electrode plate unit in the blank isolation strip for being longitudinally continuous distribution by being separated into continuously distributed electrode
Plate unit, double-layer metallization film layer after by cutting is folded be wound into capacitor after, integral capacitor device can be equivalent to more it is micro-
Small capacitances internal parallel forms；The blank for being symmetrically distributed in the electrode plate unit other side stays sideband, the blank to stay the work of sideband
With being that double-layer metallization film layer after by cutting is folded after misalignment is wound into capacitor body, when capacitor body both ends of the surface metal spraying
Ensure that the metal of spraying will not lead to power-on and power-off short circuit of polar.
Further, the electrode plate unit thickness of coating is the 1/4 of the thickness of common structural metals thin film coating；Mesh
Be the thickness that electrode plate cell operation region electrode coating is thinned, make up electric weakness in the metallic film capacitor of ordinary construction
Sometimes cannot effective self-healing defect problem, make to be dielectrically separated from for coating formation around breakdown point of volatilizing in breakdown self-healing procedure
Energy needed for area is reduced to original 1/3 or more.
Preferably, blank isolation strip width is 0.2mm or so.
Compared with prior art, the present invention haing the following advantages：
1. by the continuously distributed electrode plate unit being separated in the blank isolation strip for being longitudinally continuous distribution, after will cut
Double-layer metallization film layer is folded be wound into capacitor after, integral capacitor device can be equivalent to more small capacitance internal parallels and form,
Give full play to intrinsic self-healed protection function of the small capacitance metallization coating to electric weak point breakdown.
2. the thickness of thinned electrode plate cell operation region electrode coating, makes up in the metallic film capacitor of ordinary construction
Electric weakness sometimes cannot effectively self-healing defect problem.
3. coating is arranged to be separated into continuously distributed electrode plate unit by blank isolation strip, damage area can be effectively blocked
Electric current vertical transfer makes damage be placed restrictions between two adjacent electrode plate units, makes impact resistance electric current and the work of capacitor
Service life improves.
