Automatic separator and method to obtain circuits for microelectronics

#The present invention concerns an automatic separator to separate a print support from the related supporting sub-layer wherein the print support is normally constituted by a base material used to print circuits in microelectronics and to make up multi-layer circuits.

#An example of this print support is typically the so called green tape, which is a Du Pont® trade mark and material. However, there are other materials in the state of the art which perform the same functions or analogous functions.

#The present invention also concerns the method to obtain circuits for microelectronics on a print support.

#We shall now see the invention, in some of its variants, with the help of the attached diagrams, given as a non-restrictive example, wherein:

#FIG. 1 shows the detachment of the supporting sub-layer, in movement, with a roller;

#FIG. 2 shows the system of FIG. 1 with a view from A;

#FIGS. 1 and 4-7 show a work element 10 consisting of a print support 11 and a related supporting sub-layer 12. The work element 10, complete with holes and printed circuits on the support 11 is positioned in a first position, here schematically represented by a store 13 or by any other means coherent with the manufacturing steps upstream.

#The work element 10, when it is in the first position, is already cut from an original roll, not shown in the drawings, and subjected to all the necessary manufacturing steps of holing, printing, shaping, handling, storing and any other steps needed for the specific purpose.

#The work element 10 is subjected to the whole work cycle with the print support 11 having been combined with the relative supporting sub-layer 12.
