Description
Technical field
The present invention relates to a kind of manufacture method of high-frequency low-impedance capacitor.
Background technology
Sheet type aluminum electrolytic capacitor is to grow up on the basis of conventional aluminium electrolytic capacitor.Common lead wire type aluminum electrolytic capacitor generally adopts hexylene glycol+aqueous systems electrolyte, makes low impedance at high frequency and mainly reaches the purpose that reduces the product impedance with moisture content and then the raising electrolytic conductivity that improves electrolyte.Therefore the chip product no longer adopts hexylene glycol+aqueous systems electrolyte, and uses gamma-butyrolacton system electrolyte instead because the product body need pass through 230～250 ℃ Reflow Soldering when mounting.This electrolyte main feature is a good temp characteristic, and low temperature impedance when high-temperature stability all is better than aqueous electrolyte, in addition, this electrolyte since the high temperature saturated vapor pressure well below aqueous electrolyte, the therefore very suitable Reflow Soldering technology that is applied to.Because this electrolyte is not moisture, the amount that increases solute is very limited again, therefore, improves electrolytic conductivity and just becomes very difficult.So the high frequency characteristics of sheet type aluminum electrolytic capacitor in the market is relatively poor, resistance value is bigger.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of manufacture method that can produce the high-frequency low-impedance capacitor of the sheet type aluminum electrolytic capacitor that high frequency characteristics is good, resistance value is little is provided.
The technical solution adopted in the present invention is: the manufacture method of high-frequency low-impedance capacitor of the present invention mainly may further comprise the steps:
(1) guide pin is riveted on respectively on cathode aluminum foil and the anode aluminium foil, described cathode aluminum foil and described anode aluminium foil are selected the aluminium foil of low specific volume for use;
(2) with electrolytic paper every between described cathode aluminum foil and described anode aluminium foil and be wound into capacitor body, then with described fuse braid, described electrolytic paper is selected low close duplex paper for use;
(3) make the described fuse of braid make its impregnation electrolyte by electrolytic bath, to be assembled into naked product with aluminum hull, plug after the described fuse detachment then, described electrolyte is that to adopt ethyl dimethyl alkali phthalate or triethylamine phthalate or amidine salt be main solute, is the electrolyte of main solvent making with gamma-butyrolacton;
(4) described naked product are cleaned up;
(5) cleaned described naked product are carried out burin-in process;
(6) the described naked product after aging are sorted processing, check and reject the bad and underproof described naked product of outward appearance of electrical quantity;
(7) qualified described naked product are cut behind the pin dress bedplate capacitor that gets product;
(8) described finished product capacitor printed again braid.
The invention has the beneficial effects as follows: because cathode aluminum foil of the present invention and anode aluminium foil are with the aluminium foil of the low low specific volume of resistance value, it is main solute that electrolyte is selected for use with ethyl dimethyl alkali phthalate or triethylamine phthalate or amidine salt, gamma-butyrolacton is the gamma-butyrolacton system electrolyte of the making of main solvent, electrolytic paper is selected low close duplex paper for use, so it is good to produce high frequency characteristics, the sheet type aluminum electrolytic capacitor that resistance value is little, thereby greatly reduce the loss of product, resistance value, the filter capacity of product is improved greatly, the high frequency characteristics of product is greatly improved simultaneously, has widened product and has used on circuit board.
