摘要

Method for the construction and application of a plate interface for the electrical interconnection in control and monitoring devices with terminal outlets of the plate type or the like, comprising the phases of:- making a rigid printed circuit (1) having apertures disposed according to the layout of the output terminals of the control device;- application by screen-printing of a soldering paste onto the locations of the printed circuit corresponding to the terminals to be brought into electrical contact;- preheating of the terminals only of the control device; - assembling of the electrical interconnection plate on the control device with the interposition of a further plate (7) for the thermal pro­tection of the control device itself;- melting of the soldering paste according to a thermal cycle comprising a preheating phase, a melting phase and a succeeding slow cooling phase; and associated programming and monitoring device having output terminals for connectors of the plate-type or the like, electrically interconnected and functionally arranged by means of an interface having a rigid plate electrically connected to said terminals by welding, intended especially for use in washing machines, drying machines and the like.
