Description
Technical field
The present invention relates to aluminium electrolutic capacitor and its technologies of preparing, and in particular to a kind of surface attaching type solid-state aluminium electroloysis electricity
Container and preparation method thereof.
Background technique
Capacitor, is a kind of device for accommodating charge, and one of the electronic component largely used in electronic equipment is widely applied
Separated by direct communication, coupling, bypass, filtering, resonant tank, energy conversion, control in circuit etc..Using surface mount skill
Art can increase productivity without carrying out brill dress hole to printed board to reduce process.
Solid-state aluminum electrolytic capacitor, abbreviation solid capacitor, the maximum of it and conventional capacitive (i.e. liquid aluminum electrolytic capacitor)
Difference is to use conductive polymer material as dielectric material, so as to avoid the bulge and leakage of ordinary capacitor.
Solid capacitor has high frequency low-resistance, resistance to high ripple, wide temperature characteristics, many advantages, such as service life is long, is suitable for power filter or high frequency
In circuit, but one of its disadvantage, it is exactly that electric leakage is big.
External stress is to cause one of the reason of solid capacitor leaks electricity.Breakage can be repaired due to not containing in solid capacitor
The movable ion of oxidation film can not directly repair damaged oxidation film.Current programme " is repaired indirectly " to it.When encountering
When external force destroys its oxidation film, make solid state conductive polymer minor insulation using electric leakage Joule heat, with realization " self-regeneration ".
This method the problem is that, but when again by external force destroy macromolecular structure after, the electric leakage of product can generate rise.It leaks electricity a side
Face can cause capacitor internal temperature rise, accelerate electrolyte aging, shorten the capacitor service life；On the other hand downstream product can also be reduced
Reliability.
Other than external stress, thermal shock is also the main reason for causing capacity fall off to go up.For surface attaching type electricity
Sub- component common high temperature reflux welding technology when installing, since the temperature of traditional handicraft polymerization is lower, maximum temperature about 180
DEG C, and when the temperature of Reflow Soldering is higher, 220 DEG C, when being greater than polymerization temperature, solid capacitor is when by high temperature reflux weldering, core packet
Interior extra unreacted reactant cracks just now, and generates SO2Gas forms internal stress, sends a telegraph container casing or rubber plug protrusion becomes
Shape causes electric leakage.
In addition to this, capacitor factor itself is also to cause one of the reason of leaking electricity.
In general, the manufacturing method of solid capacitor are as follows: firstly, production anode foils, form dielectric layer oxygen on anode foils surface
Change film, one end extraction wire of anode foils forms the support portion of a thicker outer diameter as anode between conducting wire and anode foils；Its
It is secondary, with metallic aluminium make Cathode Foil, one end extraction wire as cathode, be again provided between conducting wire and Cathode Foil one compared with
The support portion of thick outer diameter；Finally, separation layer is arranged between anode foils and Cathode Foil, then by separation layer, anode foils and Cathode Foil
It winds together, forms winding-type capacitance core packet.
When production, at 60 ~ 90 DEG C, capacitance core packet is put into 2 ~ 10% ammonium adipate solution, electrochemical treatments 10 ~
30 minutes；Then it is toasted 60 ~ 180 minutes at 130 ~ 280 DEG C, separation layer is made to be carbonized；Capacitance core packet after carbonization temperature 20 ~
35 DEG C, immerse in the solution containing organic monomer and oxidant 10 ~ 40 minutes under normal pressure, polymerize under normal pressure after taking-up, 30 ~
At 210 DEG C, by 0.5 ~ 6 hour formation high conductivity organic polymer, polymeric residues are finally washed off again.
When assembling, capacitance core is first packaged into aluminum hull, is then filled with rubber plug, rubber plug is made to be completely covered by the upper of capacitance core packet
Side, the height of rubber plug are equivalent to the height of thicker support portion；By extruder tool, the nozzle of beam pressure aluminum hull upper end makes the upper end
Nozzle is completely closely sealed with rubber plug；The capacitor that finally completion is encapsulated aging process 0.5 ~ 10 hour at 105 ~ 145 DEG C, is made
Plug-in type solid-state aluminum electrolytic capacitor.
When surface attaching type solid-state aluminum electrolytic capacitor is made in plug-in type solid-state aluminum electrolytic capacitor, have using surface
The cover board of through-hole passes through anode stabilizer blade and cathode stabilizer blade, coats cover board completely and is fixed on above capacitor, then utilizes and covering
The preformed groove of plate surface is bent to 90 degree, is finally respectively implanted after so that anode stabilizer blade and cathode branch foot is passed through through-hole
In groove, that is, constitute surface attaching type solid-state aluminum electrolytic capacitor.
During producing existing solid capacitor, there is also problems in detail below: 1. conventional solid-state capacitor designs use
Carbonization technique, electrolytic paper increase through carbonization back aperture, and core pack arrangement is loose, and external force resistance ability is poor；2. core after common process polymerization
Packet is directly assembled, and core packet lacks protection；3. the lead of conventional solid-state capacitor is ordinary rigid conducting wire, using one-pass molding,
Therefore lead is flattened and when bending, and required active force is larger, is easy to pass to external force into core packet, causes capacitor internal conductive
Macromolecular structure is impaired.
