自动网版曝光机/Automatic Self-integrated Exposure Unit

一、适用范围：

    本系列设备具备光照强度均匀、光量控制稳定、光源波长稳定、抽真空度高、灯管使用寿命长等优点，适用于高精度线条、网点和高密度网线之网版曝光。

Description: 

   It is used for preparing the high quality stencils for half tone jobs and highly dense line stencils. 

二、主要特点：

Ø  均匀的光强度分布：本系列曝光机型，安装进口光源反光板，耐紫外线强度照射、抗氧化侵蚀，光源分布均匀，整版曝光量均匀稳定。

Ø  精密计算光量控制：AEXC-Ⅱ型精密计算光量计，准确控制曝光量，完全排除因灯管老化、灯光启动不稳定及电压不稳定而造成制版质量、曝光量等等不稳定的现象。

Ø  高功率紫外线灯源：可选择装配节能高效率，快启动3000W或5KW高功率紫外线曝光灯源，波长范围360 ~ 410 nm 。

Ø  高速真空吸气系统：配备无尘、静音型真空抽气泵极高张力抗紫外线橡皮布，抽真空速度均匀快速，使网版与底片能够快速、紧密、平整的贴实，适用于高精密线条和高密度网线之直接、间接网版曝光。应在净化无尘的环境下使用。

Features:

Ø  The automatic UVB series exposure machine is very easy and convenient to operate that the cycle of vacuuming, exposing and air exhausting are automatically completed with one single control.  All parameters are monitored with a programmable micro-computer, stored upto 20 sets of programmes, easily retrievable.

Ø  Even light distribution, constant light power control, stable wavelength , high power vacuum force and long service life of the lamp are the unique features of the UVB.

Ø  The reflector angle is computer-aid designed for the best light distribution.  The reflector panel are the high quality material imported from Germany.

Ø  Light integrator is employed for exposing control as it measures the actual light intensity enacting against the emulsion on the screen, not the usual timer control.  It eliminates the ill-effect due to the unstable electricity supply, aging lamps etc.

Ø  3KW or 5KW lamp(Japan) and high power oil-free, low noise vacuum pump(U.S.A.)  are employed.The vacuuming force can be as low as -600 mmHg.  Special Fabric finish vacuum blanket from America is used for holding the screen firmly intact with the glass pane.
