自動網版曝光機/Automatic Self-integrated Exposure Unit

一、適用範圍：

    本系列設備具備光照強度均勻、光量控制穩定、光源波長穩定、抽真空度高、燈管使用壽命長等優點，適用於高精度線條、網點和高密度網線之網版曝光。

Description: 

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

二、主要特點：

Ø  均勻的光強度分布：本系列曝光機型，安裝進口光源反光板，耐紫外線強度照射、抗氧化侵蝕，光源分布均勻，整版曝光量均勻穩定。

Ø  精密計算光量控制：AEXC-Ⅱ型精密計算光量計，準確控制曝光量，完全排除因燈管老化、燈光啟動不穩定及電壓不穩定而造成製版質量、曝光量等等不穩定的現象。

Ø  高功率紫外線燈源：可選擇裝配節能高效率，快啟動3000W或5KW高功率紫外線曝光燈源，波長範圍360 ~ 410 nm 。

Ø  高速真空吸氣系統：配備無塵、靜音型真空抽氣泵極高張力抗紫外線橡皮布，抽真空速度均勻快速，使網版與底片能夠快速、緊密、平整的貼實，適用於高精密線條和高密度網線之直接、間接網版曝光。應在淨化無塵的環境下使用。

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.
