PROBLEM TO BE SOLVED: To improve the compatibility of a Sn/Ag solder for use on a glass product for motor car, and to especially deal with the problems of cracking in a Sn/Ag solder, that is normally found in the thermal cycling test, by allowing for usage of a Pb-free solder (other than a Pb-free solder containing indium).SOLUTION: A glazing includes at least one glass layer having a conductive component at least on one surface, and an electric connector connected with the conductive component by solder joint. The solder of the joint is lead-free and has a composition containing tin and silver, preferably 98Sn2Ag. The electric connector is subjected to nickel plating for touching the solder, and is a contact preferably containing 99-99.99 wt% of Cu.SELECTED DRAWING: None
【課題】自動車用ガラス製品上での使用のために、Sn/Agはんだの適合性を改善すること、特に、(インジウム含有のPbフリーはんだ以外の)Pbフリーはんだの使用を可能にして、熱サイクル試験で通常見られる、Sn/Agはんだにおける亀裂の問題に対処すること。【解決手段】少なくとも1つの表面上に導電性コンポーネントを有する少なくとも1つのガラスの層、およびはんだ接合によってその導電性コンポーネントに電気的に接続された電気コネクタであって、その接合のはんだがスズおよび銀、好ましくは98Sn2Ag、を含む組成を有する無鉛であり、その電気コネクタは、はんだに接触するためのニッケルめっきを施され、銅、好ましくは99〜99.99wt%のCuを含む接点とする。【選択図】なし
