Description
Multilayer ceramic chip capacitors (MLCC) are used in civilian electronic equipment and devices, such as computers, telephones, and programmable switches. The weight of this MLCC capacitor is approximately 0.007 g; this dataset includes primary raw materials, auxiliary materials, energy, atmospheric emissions, and waste from the production process; infrastructure such as manufacturing of production equipment and construction of factory buildings are excluded from the system boundary of the dataset; the life cycle inventory is compiled from data sourced from multiple references; the production of ceramic capacitors involves processes including batching, tape casting, inner electrode printing, layer stacking, isostatic pressing, cutting, debinding, sintering, chamfering, cleaning, sorting, termination plating and firing, electroplating, and testing and screening.
Activity Description
The production of ceramic capacitors includes processes such as batching, tape casting, printing internal electrodes, laminating, isostatic pressing, cutting, binder removal, sintering, chamfering, cleaning, sorting, terminal plating and firing, electroplating, and testing and screening.
Process Description
Multilayer ceramic chip capacitors (MLCCs) are constructed by stacking ceramic dielectric sheets printed with electrodes (inner electrodes) in a staggered manner, which are then co-fired at high temperature to form a ceramic chip. Metallic layers (outer electrodes) are subsequently applied to both ends of the chip, forming a structure resembling a monolithic block. MLCCs can be used in civilian electronic equipment and devices, such as computers, telephones, and programmable telephone exchanges.
