生产层压板用之不锈钢板的质量好环直接影响层压板的质量。例如,它不仅影响层压板的厚度公差,表面光滑平正,色泽光亮均一等情况,而且也影响层压板的吸水性及表面电阻。大家知道,对用于高频条件下工作的层压板要求要有反光如镜极均匀的一层树脂薄膜。否则,表面电阻降低,介质损耗增大,其经受湿后性能显著恶化。
The good quality of the stainless steel sheet used to produce the laminate directly affects the quality of the laminate. For example, it affects not only the thickness tolerance of the laminate, the smoothness of the surface, the uniform brightness of the color, but also the water absorption and the surface resistance of the laminate. As we all know, for the work of high-frequency laminate required to have a reflective mirror as a very uniform layer of resin film. Otherwise, the surface resistance decreases, the dielectric loss increases, and its performance deteriorates significantly after it has been wetted.
