Device for aligning prefabricated circuit with a photographic plate to make printed circuits

Abstract

Abstract A DEVICE FOR ALIGNING A PREFABRICATING CIRCUIT WITH A PHOTOGRAPHIC PLATE AND EXPOSING THE PLATE TO PRODUCE PRINTED CIRCUITS AND SOLID CIRCUITS, WHICH COMPISES A MICROSCOPE AND A MANIPULATOR INCLUDING A MAIN MICOMETER MOUNTED IN A BUSHING AND HAVING AT ITS ONE END A DIAL FOR SETTING THE OPTIMAL VALUE OF THE GAP BETWEEN THE PREFABRICATED CIRCUIT AND THE PHOTOGRAPHIC PLATE, AND TERMINATING AT ITS OTHER END IN A SCREW TIP, THE DEVICE IS FURTHER PROVIDED WITH A MECHANISM FOR VERTICALLY MOVING THE PREFABRICATED CIRCUIT, FASHIONED AS A ROD WITH A FLANGE, MOUNTED IN A MOVABLE SLEEVE, SAID MOVABLE SLEEVE ALSO HAVING A SECOND FLANGE ON WHICH THE FLANGE OF THE ROD RESTS, THE UPPER END OF THE ROD HAVING A SUPPORT HUB LOSEELY MOUNTED THEREON AND CARRYING A HEMISPHERE WHICH HAS A MICROSCOPE TABLE DISPOSED THEREON, THE SLEEVE HAVING A LEVER PIVOTALLY SECURED THEREON, RESTING UPON THE ROD AND OPERATIVELY CONNECTED WITH THE PIVOT OF THE MAIN MICROMETER SCREW, AND THE FLANGE OF THE SLEEVE HAVING A BUSHING OF THE MAIN MICROMETER SCREW RIGIDLY SECURED THEREIN. THE DEVICE PROVIDES A VERY ACCURATE AND PRECISE ALIGNMENT OF A PREFABRICATED CIRCUIT WITH A PHOTOGRAPHIC PLATE, WHICH ALIGNMENT DOES NOT GET DISTURBED DURING SUBSEQUENT SECURING OF THE CIRCUIT AND THE PHOTOGRAPHIC PLATES PRIOR TO EXPOSURE OF THE PHOTOGRAPHIC PLATE.
