TERMINAL STRUCTURE FOR GLASS PLATE WITH CONDUCTIVE SECTION AND GLASS PLATE ARTICLE UTILIZING SAME

摘要

Disclosed is a glass plate article having a feed terminal structure to be connected with a feeding portion of a glass plate with a conductive portion, the glass plate article being characterized by that the feed terminal structure has at least one terminal seat subjected to a surface connection with the feeding portion through a lead-free solder alloy, that the terminal seat has a laminar form prepared by removing corner portions (soldering avoidance regions), each defined by a line connecting two points that are away from each of two vertices of one side of a square or rectangle by 1.6 mm or greater and are on two sides extending from each vertex, from the square or rectangle, that a connection area per each surface connection is from 8 mm 2 to 98 mm 2 , and that the terminal seat is soldered to the feeding portion by using the lead-free solder alloy, the lead-free solder alloy is a Sn-Ag-Cu-series, lead-free solder alloy that has a dispersion/precipitation strengthened structure containing 1.5 to 4 mass % of Ag and 0.5 to 2 mass % of Cu and has a Young's modulus of 40 GPa or higher at room temperature.
