<p>PURPOSE:To intend to improve heat resistant property of thick film resistance, by using amorphous glass flit whose softening temperature is a specified temperature value. CONSTITUTION:Amorphous glass whose softening point is 700-850 deg.C is ground, and glass flit whose particle diameter is under about 3mu, for example, is prepared. This glass flit and electro-conductive component are mixed, furthermore, vehicle in which ethyl-cellulose is solved in alpha-terpineol is added, and they are kneaded and are made as paste. Thick film resistance is formed by painting such that an electrode that is formed on an insulating base plate is connected by paste and then burning it at the temperature which is over 150 deg.C than softening point of glass flit. Such thick film resistance has excellent heat resistant property, and it can load electric power of over twice, compared with former resistance.</p> |
