High Quality Exposure machine and corrosion machine with Good Packing.

Exposure machine is a machine that transmits image information from film or other transparent body to a surface coated with photosensitive material by turning on the light, emitting ultraviolet wavelengths.

Exposure machine In the printed circuit board manufacturing process, one of the most critical processes is to transfer the negative image to the copper foil substrate. First, coat a layer of photosensitive material (such as liquid photosensitive adhesive, photosensitive anti-corrosion dry film, etc.) on the substrate.

Then, the photosensitive material coated on the substrate is irradiated with light to change its solubility. The resin in the non-photosensitive part does not polymerize and dissolve under the action of the developer, and the resin in the photosensitive part remains on the substrate to form an image. This process is exposure, which is the process completed by the exposure machine in the production of printed circuit boards.

Features of exposure machine:

1. Energy saving and cost reduction - LED consumes only about 15 watts of energy when it reaches a certain brightness, while the traditional lamp will consume 1500 watts of energy to achieve the same brightness. It can save 80% of energy, so LED lights are very energy-saving and environmentally friendly.

2. The light source system is guaranteed for 3 years and has a long service life - the life of the LED light exceeds 20,000 hours.

3. Wider application range - The light emission of LED lights is not infrared heating, and the heat release is low, so it will not affect the transmission of those media that are easily deformed by heat (such as foam sheets, foils, PVC, etc.) during the printing process. In this way, the application of the media is more extensive.

4. Fast response (switching) time - LED lights do not need preheating, can print immediately after startup, and can improve productivity.

5. The high-safety LED lamp has no ultraviolet radiation, no ozone release, and is not easy to break.

6. High stability - The printing quality of UV inkjet printers has a lot to do with the UV drying and curing process. The stability of the LED lamp makes the output energy predictable and stable, and the printing effect is predictable and stable.
