Method for the manufacture of foil capacitors

A process for producing laminated capacitors includes stacking of metallized plastic films. It includes a step of winding of at least one pair of metallized plastic films, this step being separated into three phases, a first phase of making finishing turns and during which the films are demetallized so that their superposition does not lead to any additional capacitance in the final component, a second phase of superposing the films so that they contribute to the capacitance of the final component and during which the films are demetallized near their edges, and a third phase intended to perform finishing turns under the same conditions as during the first phase, wherein the demetallizations of the films occurring in the successive phases are performed by etching. The process for producing laminated capacitors can also include at least one step of demetallization of metallized plastic films appearing in the form of widths of great width intended to be cut into elementary ribbons, in which the demetallization is performed by etching.
