With the rapid development of market demand, the PCB industry's requirements for production capacity are increasing day by day. In order to rapidly increase production capacity on the premise of ensuring quality, a new revolution has been launched in the field of PCB exposure, that is, UVLED transformation of traditional exposure machines, using UVLED The light source replaces the traditional mercury lamp.
At present, the traditional line exposure machines on the market have already undergone large-scale UVLED transformation, and the exposure machines are also following, ushering in a new wave of transformation!
Exposure machine refers to the equipment that transfers the image information on the film or other transparent body to the surface coated with the photosensitive material by turning on the light to emit ultraviolet rays of the UVA wavelength.
The touch screen is the automatic control system of the exposure machine, including the scheme of the control system, the hardware configuration, the address assignment of the PLC input and output points, and the software control program. Features, improve the production quality and efficiency of the exposure machine.
