Abstract
In a method of making a multilayer printed circuit board, circuit patterns 16, 18, 20, Fig. 2, are formed on a plurality of green ceramic sheets 10, 12, 14 with a paste comprising powdered metal or reducible metal compound in a volatile binder, through-holes 22, 24, 26 in said sheets also being filled with said paste the sheets are then stacked and fired to sinter the sheets together, Fig. 5, to convert any metal compound to the metal, and to cause the metal to form capillary paths 42 along said circuit pattern finally the said capillary paths are filled with molten conductor metal 52. A preferred ceramic for the sheets is zirconium alkaline earth porcelain (ZAEP) aluminas, beryllias, forsterites, steatites, and mullites may also be employed. Preferred metals include Mo, Mo-Mn, Zr, Fe, Cb, W, Ti, Ta, and mixtures thereof compounds of the said metals and oxides of Li-Mo may alternatively be used. The capillary paths may be either metallized tubes, as shown, or porous lattice-like structures they are filled by immersion in a bath of molten metal, e.g. Cu or Al, in a reduced pressure atmosphere alternatively, metal preforms are butted against the capillary ends and melted. A preferred composition of ZAEP is:- After milling for 8 hours the slurry is dried, pulverized, calcined, repulverized and micromilled, after which it is mixed with resin, solvents, and wetting and plasticizing agents in the following proportions:- In a first example, ZAEP green sheets are screen printed with a circuit pattern of paste comprising 40 gms powdered MoO 3 and 13À5 gms. medium containing betaterpenyl and ethyl cellulose. After stacking, the sheets are subjected to a burn-off in air at 400 C. followed by firing in dry H 2 at 1210 C. Capillaries are filled by immersion in a molten Cu bath at 1140 C. In another example, terephthalic acid is added to the paste, the sintering is carried out at 1285 C. in, a moist H 2 atmosphere, and the capillaries are filled in an Al bath at 700 C. Other examples using Mo-Mn powder to form the paste are described in the Specification.
