Exposure machine precautions


Exposure machine] is a special equipment for producing high-density, high-precision printed circuit board image transfer. It can be used for dry film exposure, and can also be used for exposure of wet film such as liquid photo-resistive film and liquid photoresist film. .
Exposure machine product features:
1. The vacuum controller and the exposure time can be set by the microcomputer controller, which is convenient to operate, and each time the printing, pumping, exposure and exhausting are completed.
2. 99 groups of memory modes controlled by microcomputer can be called at any time.
3. The traditional funnel design is eliminated inside the body, adopting a more scientific and reasonable streamline type, making full use of the uniform energy of the light source to refract the entire glass surface, improving the multi-color, four-color dot plate making effect
4, the reflector is made of reflective material AR481# reflector, which can be refracted to four corners, uniform light intensity, and reflective efficiency up to 90%
5, equipped with precision calculation of light quantity device, long and stable light
6, this machine uses high quality Philips imported lamp, imported light source reflector
7, with automatic voltage regulator to ensure accurate exposure network cable, imported vacuum pump, pumping vacuum can reach -0.8MPa or more.
8. Use special centrifugal cooling fan to fully dissipate the lamp to ensure the temperature inside the machine is stable, thus achieving normal energy of the lamp and improving the stability of the plate.
9. This machine is suitable for high-precision line, dot, and height network wire and other high-quality screen printing exposure
Advantages of the exposure machine
1, 650 × 650mm nearly parallel light large-area double-sided exposure operation, illuminance uniformity of more than 85%, providing large-area precision machining and higher processing efficiency.
2. The advanced touch-type human-machine interface control mode is more convenient to use and provides a more complete production management system.
3, configuration: UV energy calculator exposure control system; self-diagnosis function and fault prompt monitoring system; dry vacuum pump vacuum device (normal vacuum pressure 650mm / hg or more) and other systems.
4. Suitable for high precision double panel processing.
