Abstract
An electromagnetic shielding plate having a glass substrate and a geometric pattern formed on the substrate, in which the geometric pattern contains (a) an inorganic filler selected from the group consisting of metals and metal oxides, and (b) a glass component having a softening point of about 200 to 700° C.
Claims21
An electromagnetic shielding plate comprising a glass substrate and a geometric pattern formed on the substrate, wherein said geometric pattern comprises (a) an inorganic filler selected from the group consisting of metals and metal oxides, and (b) a glass component having a softening point of about 200 to 700° C.
A method for producing the electromagnetic shielding plate of the present invention comprising the steps of:
- forming a geometric pattern by printing a pattern with a paste containing an inorganic filler selected from the group consisting of metal powder, metal alloy powder, metal oxide powder and organic metal complexes and organic acid salts of platinum metals, a glass frit, a binder resin and an organic solvent, and
- baking said geometric pattern until a weight of an organic material in the pattern is decreased to 10% or less of the weight of the organic material prior to baking.
