NGK FILTECH LTD 公司发展 MEGCON 纯水抗静电处理系统,

此系统使用特殊过滤膜让二氧化碳进入纯水中混合使纯水的电阻值能被控制在 0.2~2 Mohm-cm. 不像传统方式将 CO2 气体或金属镁直接融入纯水中,产生二次污染一样,MEGCON 的优点是不会产生二次污染及气泡。

   by performing regular inspections.

 Ultrapure Water Cleaning

 Electrostatic damage When there is friction between nonconductors of different materials,
 static electricity is generated.
 The causes of static electricity include friction, separation, impact, streaming, etc.
 There is much danger of static electricity generation in the cleaning process.

 ●Electrostatic discharge damage

 Fine wiring can be damaged by static electricity.
 The wiring and transistors in liquid crystal displays (TFT) can be damaged.
 Damage to even a single location in the minute pattern can lead to quality problems occuring for the entire product.

 ●Particle reattachment

 When static electricity is formed, not only is it difficult to separate foreign particles,
 but the problem of foreign  particles that have already
 been detached being attracted and attached again also occurs.
 here is also the problem of cutting particles becoming reattached to important parts of the wafer during the dicing process,
 resulting in defects occurring in later processes such as bonding.

Features of MEGCON Ⅱ

 The MEGCON Ⅱ aims to increase the efficiency of cleaning processes and has improved functionality.

  ■ Automatic control system

 The following control methods can be used according to the application, allowing the device to be utilized in
 its optimum state.
 ● Sensor measurement control
 ● Dissociation calculation control
 ● Flow input control .

 ■ Membrane drying mechanism

 Maintenance of performance and the life of the membrane have been greatly improved by installing an obstruction  
 removal mechanism that uses vapor in the gas inlet.

  ■ Point of use monitor(optional)

   The actual resistivity at the point of use of the cleaning operation can be measured.

  ■ As part of our new corresponding product series, we have released MEGCON II with CE marking.

  ■ Data storage system(optional)

 Data for resistivity, temperature and flow can be fed into a personal computer and displayed on a graph.
 The data is stored and can be utilized in quality control of cleaning operations.
 If the carbon dioxide gas level alarm has been installed,the gas level can be viewed on screen.
