Title:
CONDUCTIVE PASTE
Document Type and Number:
Japanese Patent JPH0729414
Kind Code:
A
Abstract:

PURPOSE: To obtain a conductive paste without poor continuity occurring in a through hole of a fluorescent character display tube.

CONSTITUTION: An insulating layer is placed on a positive electrode substrate of aluminum thin film, having wiring. A positive electrode conductor is formed on the insulating layer and a phosphor layer is placed on this positive electrode conductor, thereby constituting a positive electrode. A through hole is formed in the insulating layer. Conductive paste is filled in the through hole, so that the wiring and the positive electrode conductor are electrically connected together. In the conductive paste, which is a mixture of Ag, glass and vehicle, 1-40wt.% of Zn or Sb, or of the two together, for the Ag is added. Zn or Sb in the composition acts as a catalyst, and Ag in the composition constitutes an alloy with aluminum as the objective of connection, so that extremely stable electrical connection is obtained.
