Abstract: Low relative permittivity plastic elliptical lenses in combination with integrated focal plane arrays are a promising solution to be used in the future mm- and sub-mm-wave systems. Their ...

Abstract: This paper presents a robust method for stall detection of stepper motors controlled in open loop. The open loop control type eliminates the need for feedback sensors, and since the cost ...

昨天一张图流传出来了，光刻机再次发酵，稳顶聚芯国产高精度Stepper光刻机顺利出厂 稳顶聚芯是一家成立时间较短，所以资本市场里股权或是直接合作的信息相对较少，我们重点就从Stepper中文叫步进重复投影曝光入手 晶瑞电材：线光刻胶是目前IC制造商大量 ...
