Electrolytic capacitor manufacturing process

(1) etching ( Expand surface area) The effect of etching is expanded aluminum foil surface area. Etched in chloride solution is an alternating or direct current electrochemical process. (2) into ( Formation of the dielectric layer) To be formed in the anode aluminum foil surface dielectric layer ( 氧化铝) In the process. General will become the aluminum foil used as anode. (3) cut in accordance with the requirements for the size of the different products to the aluminum foil ( The cathode foil and anode foil) And electrolytic paper shear as the need to the size of the (4) insert the foil between anode and cathode foil, electrolytic paper and then winding into cylindrical, cathode foil on the winding process and the anode foil connection terminals. (5) including dip dip is immersed element child process in the electrolyte. The electrolyte can further repair the dielectric layer. 6 sealing seal after the child is the element in aluminum shell with sealing material ( Rubber, rubber cover etc. ) The process of sealing. (7) aging Taken) After aging is to seal the process of the capacitor voltage at high temperature. This process will be the dielectric layer when the cutting and winding process to fix some of the damage. Today all inspection, the packing after aging, will be electric property inspection for all products. And terminal processing, braiding, etc. The last part packing. Pet-name ruby shipment inspection according to the inspection of the product inspection standards. Attending the shipment
