Features: 1. The stencil vacuum adsorption and high-elastic blanket make the stencil and the film closely fit, and the negative film pattern is reproduced. 2, the use of high-performance vacuum compressor, vacuum adsorption, excellent recovery performance. 3. Quick-start type complete exposure system; the light intensity is stable and uniform, and the exposure pattern lines are fine. 4. After the vacuum inhalation process is completed, the exposure process begins, and the vacuum adsorption and exposure processes are integrated.
