为适应我国电子工业的发展需要,江苏省冶金研究所同无锡市冶炼厂共同完成了研制J K—2铜合金带的扩大试验和小批量工业性试生产。产品经电子部、航天部等10个单位试用认为:J K—2铜合金带是目前国内较为理想的框架材料,为集成电路塑封材料国产化打下了良好基础。同时,该产品还可作为一种较好的新型弹性材料用于各种接插件。江苏省冶金厅于1985年11月29日至30日在无锡市组织召开J K—2(集成电路引线框架
In order to meet the needs of the development of China’s electronics industry, Jiangsu Metallurgical Institute and Wuxi Smelter jointly completed the development of J K-2 copper alloy tape to expand the trial and small batch of industrial pilot production. Products by the Ministry of Electronics, Aerospace Department trial of 10 units that: J K-2 copper alloy belt is currently the ideal framework for the domestic material, plastic packaging materials for the integrated circuit laid a good foundation. At the same time, the product can also be used as a better new elastic material for a variety of connectors. Jiangsu Provincial Department of Metallurgy held a meeting in Wuxi City from November 29 to November 30, 1985, J K-2 (Integrated Circuit Lead Frame
