1.前言高产出,高成品率,低原材料消耗,低能耗,低人力消耗——这是每个光盘复制者追求的目标。今天,先进的闭环控制系统可以实现这一目标。对于不同格式的盘片,对于不同的工艺过程,需要不同的控制系统。我们将依次介绍这些系统。本文首先介绍Dye ODPROCON—CD-R染料旋涂工艺的在线自动控制系统。该系统已经在实际中投入使用。2.CD-R染料OD闭环控制理论2.1 染料膜厚测试光密度(OD=-logT)控制的目标是在盘片上旋涂出厚度均一的染料层。根据CDR-SIM软件对CD-R光学参量的仿真计算可知,应该在吸收峰处(λ_(max))做光密度 1. Introduction High output, high yield, low raw material consumption, low power consumption, low labor consumption - this is the goal pursued by each disc reproducer. Today, advanced closed-loop control systems can achieve this goal. For different formats of discs, different processes require different control systems. We will introduce these systems in turn. This article first introduces the Dye ODPROCON-CD-R dye spin-on process online automatic control system. The system has been put into practical use. 2. CD-R dye OD closed-loop control theory 2.1 dye film thickness test Optical density (OD = -logT) The goal of control is to spin-coat a uniform thickness of the dye layer on the disk. According to the simulation calculation of CD-R optical parameters by CDR-SIM software, we can see that the optical density should be done at the absorption peak (λ max)
