Abstract
A method for the manufacture of foil capacitors with metallized plastic films, said method comprising the following steps: PA1 coiling at least one pair of metallized plastic films so as to form the stacked structure of the capacitors; PA1 metallizing the lateral faces of the coiled structure in order to create the plates of the capacitors; PA1 cutting out the coiled and metallized structure, or parent capacitor, into semi-finished capacitors; PA1 putting the semi-finished capacitors and their connection wires through a cleansing flux; PA1 soldering the connection wires to the plates of the semi-finished capacitors; wherein the soldering is done by wave soldering and wherein, between said metallization and said cutting, a heat treatment operation designed to give the plastic film the characteristics needed to withstand the wave soldering and a new metallization designed to ensure the mechanical and electrical quality of the connections are carried out successively.
