Abstract

A method and apparatus for processing green-tape type circuits, whereby through contacts and electrical circuits are obtained on a thin foil of alumina in the raw state or another analogous or like material containing reference holes or marks (29) and connecting micro-holes (30) by means of a printing process with a conductive material, the green-tape foils being able to arrive from a wound roll of basic material or from a stock of already cut foils, in which method a green-tape foil (10) complete with through connecting holes (30) and reference holes or marks (29) is positioned on a conveyor belt (12) comprising at lest specific zones of transpirable material (3) and loaded with the green-tape foil (10), which is identified as a position in relation to the belt (12), is then printed after reciprocal positioning with a printing means, is dried and discharged, the apparatus comprising at least one loading station (13), a station (15) to identify the position of the green-tape foil (10), a printing station (18) and a drying station ( 19), these stations being able to be individual single stations or to be combined in two or more stations.
