绪论 光盘基板采用注塑成型方法来制造。注塑成型条件 决定基板沟槽的形状,因此生产管理方面是一项很重要 的管理项目。而且,验收光盘母盘时沟槽是否达到规格, 需要进行测试检验。这次开发成功的沟槽评价装置具有 使用方便,操作简单,实用性强等特点。并且,在光盘 制造所有工程上都可以使用此装置。在此作详细报告。 Introduction disc substrate using injection molding method to manufacture. Injection molding conditions determine the shape of the substrate groove, so the production management is a very important management project. Moreover, the acceptance of CD-ROM slot when it reached the specifications, the need for testing. The successful development of trench evaluation device with easy to use, simple operation, practicality and so on. And, this equipment can be used on all projects of CD manufacturing. Make a detailed report here.
