近年来,随着我国电子工业、无线电工业、精密仪器、仪表等工业的突飞猛进的发展,在我们日常外协工作中,经常碰到一些薄壁(通常厚度在0.15—0.20毫米范围之间)元件焊接。焊接件的材料常采用不锈钢,可伐(KoVar 该属系一种铁镍钴合金,它具有一定的膨胀系数,因此能与玻璃、陶瓷进行封接,在电真空工业中使用较广)、铂等材料。 In recent years, with the rapid development of China’s electronics industry, radio industry, precision instruments, instruments and other industries, in our daily work of outsourcing, often encounter some thin-walled (usually 0.15-0.20 mm thickness range) components welding. Welding materials are often made of stainless steel, Kovar (KoVar belongs to a nickel-cobalt alloy, which has a certain coefficient of expansion, it can be sealed with glass, ceramic, widely used in the vacuum industry), platinum Other materials.
