Process for manufacturing multilayer ceramic capacitors

Claim 1

A PROCESS OF FORMING A CERAMIC CAPACITOR OF EXTREMELY SMALL SIZE AS COMPARED TO CAPACITY FROM CERAMIC MATERIALS, WHICH COMPRISES FIRST FORMING AND DRYING THIN COHERENT FLEXIBLE GREEN CERAMIC SHEETS CONTAINING A PLASTIC BINDER FROM A SLIP DEVOID OF AIR BUBBLES, BY CASTING, ELECTRODING FACES OF THESE SHEETS WITH A REFRACTORY METAL WHICH DOES NOT OXIDIZE AT THE FIRING TEMPERATURE OF THE CERAMIC COMPOSITION SO THAT THE ELECTRODE AREAS ARE OUT OF REGISTER AND ARE EXPOSED ALTERNATELY AT DIFFERENT EDGES, PUNCHING THE SHEETS SO AS TO FORM PLATES OF DESIRED DIMENSIONS WITH THE ALTERNATE EDGES EXPOSED ON DIFFERENT SIDES OF THE PLATE AND STACKING SUCH PLATES, SUBJECTING THE STACK TO A PRESSURE OF ABOUT 10 TO 20 TONS PER SQUARE INCH WHILE CONFINING LATERAL DISPLACEMENT OF SUCH STACK, AND THEREUPON FIRING THE STACK AT A MATURING TEMPERATURE OF BETWEEN 2,100 TO 2,600*F. TO BURN OFF THE BINDER AND MATURE THE SHEETS, CONDUCTING MATERIAL BEING APPLIED ALONG THE EXPOSED EDGES OF THE ELECTRODES TO GIVE PARALLEL CONNECTIONS, AND AFTER FIRING, APPLYING LEADS TO FORM THE COMPLETE CAPACITOR.
