磁心存储器是电子计算机中目前仍广泛采用的一种主要的内存储器。随着计算技术事业的不断发展,对磁心存储器提出了高速度、大容量的要求。由于这种高速度、大容量的要求,除在磁心材料和制备工艺做不断改进外,磁心外形尺寸亦在逐年缩小,国外目前已采用12×7×1.2密耳(即0.30×0.18×0.03毫米)的磁心,因此,磁心板的穿线工艺在内存储器的研制过程中就成为一个棘手的问题。这里介绍国外一种磁心板穿线的模板,以供参考。工作原理磁心在模板上以振动和抽气等方法使其落入模板的空穴中(如图1所示),这样,磁心 Magnetic core memory is still a widely used main memory in electronic computers. With the continuous development of computing technology, the core of the memory made high-speed, high-capacity requirements. Due to the high speed and high capacity requirements, in addition to the continuous improvement of the core material and the preparation process, the core size has also been reduced year by year. In foreign countries, 12 × 7 × 1.2 mils (0.30 × 0.18 × 0.03 mm ) Of the core, therefore, the core of the threading process in the memory of the development process has become a thorny issue. Here introduced a foreign core plate threading template for reference. Working principle The magnetic core in the template to vibration and suction and other methods to fall into the template cavity (as shown in Figure 1), so that the core
