Use of SDI Mylar Membrane Imported from the United States
Details of the use of SDI Mylar membrane imported from the United States are as follows:
A. At present, SDI Mylar film in the United States has eliminated a layer of yellow protective film during manufacturing, which does not affect the quality, and enhances the exposure rate (about 95%). The development effect of exposed fine lines or fine characters is very clear, which greatly improves the quality of the product. At the same time, because of the high exposure rate, it can reduce the exposure energy, save the exposure energy and surrounding consumables (exposure tubes, water jackets, etc.), which will reduce the overall cost of production.
B. In the production process, the main reasons for the rupture of Mylar film are as follows:
1. Don't tighten the exposure frame too tightly, and loosen it a little, so that the machine will not pull the Mylar film too tightly when vacuuming.
2. When cutting, the edge of the board is not smooth, which will puncture the Mylar film. Keep the edge of the board smooth as far as possible to protect the film and Mylar film.
