Abstract
The invention discloses a method for producing a paster electrolytic capacitor with a high product pass rate. The method comprises the following steps: preparing core covering; performing assemblage; flatting a terminal pin; performing burn-in; assembling a seat board. A technology of the invention is reasonable and simple. A process of burn-in is arranged after the process of flatting the terminal pin. Therefore, an oxide film, which is pulled and is destroyed during flatting the terminal pin, can be restored through the burn-in. A passing rate of the product can be increased by more than 10%-15%. And especially the passing rate of solid polymer aluminum electrolytic capacitors can be increased by more than 20%.
Description
Technical field
The present invention relates to a kind of electrolytic capacitor production method, specifically a kind of paster electrolytic capacitor production method.
Background technology
In electronic product is produced, for realizing the packaging density height, reduce volume, the weight of electronic product, often use surface installation technique (SMT); It requires electronic component is surface mount elements, generally adopts after the SMT, and electronic product reliability is high, the antivibration ability is strong; The welding point defect rate is low, and high frequency characteristics is good, has reduced electromagnetism and radio frequency interference; Easily be automated, enhance productivity, save material, the energy, equipment, manpower, time etc.
At present, in the paster electrolytic capacitor is produced, be generally group is found good electrolytic capacitor earlier through overaging, again terminal pin is flattened seat board assembling then.In flattening the process of terminal pin; Because mechanical action and the effect of flattening mold external force; More or less can spur the inner core packet portion of capacitor, will damage the oxide-film after aging the reparation, serious will become waste product (generally having 10 ﹪～20 ﹪ to become waste product); Have a strong impact on quality and qualification rate, improved the production cost of enterprise.
Summary of the invention
The purpose of this invention is to provide the high paster electrolytic capacitor production method of a kind of product percent of pass.
The present invention adopts following technical scheme to realize its goal of the invention, a kind of paster electrolytic capacitor production method, and it may further comprise the steps:
⑴ prepare the core bag:
⑵ group is upright:
⑶ terminal pin is flattened: for ease of the assembling seat board, will lean on the root of electric capacity one end lead-in wire to flatten;
⑷ aging;
⑸ seat board assembles: the capacitor fit on plastics seat board after lead-in wire is flattened, worn out.
Among the step ⑶ of the present invention, the length that terminal pin is flattened is more than 5 ㎜.
Because adopt technique scheme, the present invention has realized goal of the invention preferably, its technology rationally, simply; After aging process was arranged on terminal pin and flattens, the oxide-film that like this, in terminal pin is flattened, pull, destroys can be repaired through aging; Improved the qualification rate of product greatly; Qualification rate improves that 10 ﹪～more than 15 ﹪, particularly to the solid-state polymer aluminium electrolytic capacitor, its qualification rate improves more than 20 ﹪.
Embodiment
Below in conjunction with embodiment the present invention is described further.
A kind of paster electrolytic capacitor production method, it may further comprise the steps:
⑴ prepare the core bag: with positive and negative electrode aluminium foil, electrolytic paper and lead-in wire, process required core bag through thorn, riveting, coiling, impregnation, as far as the production of solid electrolytic capacitor, the production process of core bag is thorn, riveting, coiling, carbonization, impregnation, curing.
⑵ group is upright: the same plug of core bag, the aluminum hull that will prepare through step ⑴ are packaged into capacitor through automatic assembling machine.
⑶ terminal pin is flattened: for ease of the assembling seat board, will lean on the root of electric capacity one end lead-in wire to flatten; The present invention is in step ⑶, and according to the size of capacitor, the length that terminal pin is flattened is 5 ㎜ above (present embodiment is 5 ㎜).Present embodiment adopts cam link drive mould that terminal pin is pushed and flattens.
⑷ aging; For repairing, capacitor is placed on the aging regular hour of switching in the ageing oven that meets aging temperature owing to ruined oxide-film in the manufacturing process.
⑸ seat board assembling: with lead-in wire flatten, aging good capacitor fit on plastics seat board.
Technology of the present invention rationally, simply; After aging process was arranged on terminal pin and flattens, the oxide-film that like this, in terminal pin is flattened, pull, destroys can be repaired through aging; Improved the qualification rate of product greatly; Qualification rate improves that 10 ﹪～more than 15 ﹪, particularly to the solid-state polymer aluminium electrolytic capacitor, its qualification rate improves more than 20 ﹪.
