Abstract
The present invention discloses the conducting polymer solid-state capacitor of long-life a kind of, including aluminum hull, core body, plug and lead-out wire, the core body is located in aluminum hull, the plug is located on core body and seals core body, one end of the lead-out wire is located in core body and is connected respectively with the both positive and negative polarity of core body, and drawn from plug, the outside of the aluminum hull forms resistance ring by suppressing, and the electrode aluminium foil in the core body also includes pre-treatment step：A, after aluminium foil being carried out into chemical conversion treatment into 45~60% ammonium adipate, the depolarising processing in the phosphoric acid and the mixed solution of 5~10% boric acid for immersing 15~20%；B, after depolarising is handled, enter back into and electrolysis chemical conversion is carried out in sodium dihydrogen phosphate.For the present invention by being repeatedly melted into depolarised electrolysis processing, the grandad for being has higher bulking value, it is ensured that has the more long-life in the case of Low dark curient.
Description
Technical field
The invention belongs to capacitor production equipment technology, and in particular to the whole pin correction welder of capacitor pin.
Background technology
With the high speed development of electronics industry, capacitor is increasing as important electronic component usage amount.The market prospects of especially high-end product solid-state capacitor are more and more wide, and the process such as the production of solid-state capacitor is needed by cutting, follow closely volume, Jiao Gai groups are stood, welding, chemical conversion, impregnation, polymerization, sealing group are stood, immersion, stamp, aging, appearance test, cutting and packaging.But because solid capacitor is in by immersion and ageing process, the polymerisation run of conducting polymer can be modified to aluminium foil surface, so as to influence the life-span of solid-state capacitor.
The content of the invention
Goal of the invention：For above-mentioned existing problem and shortage, it is an object of the invention to provide the conducting polymer solid-state capacitor of long-life a kind of.
