The production of aluminum electrolytic capacitors involves processes such as foil cutting, winding, element impregnation, assembly, cleaning, sleeving, series arrangement, aging, and inspection. The production of solid tantalum electrolytic capacitors includes key steps such as powder mixing, pressing and forming, sintering, formation, coating, silver paste impregnation, chip mounting and curing, molding and curing, trimming, aging, testing, and tape-reeling for storage. The production of ceramic capacitors mainly involves processes including raw material preparation, tape casting, internal electrode printing, film stacking, isostatic pressing, cutting, binder removal, sintering, chamfering, cleaning, sorting, terminations, firing terminations, plating, and testing and screening. The production of metallized polypropylene film capacitors consists of two main processes: film metallization (pre-treatment, vacuum deposition, post-treatment, crystallization, slitting, inspection) and film capacitor manufacturing (winding, hot pressing, welding, potting, lead attachment, testing and sorting).
