How to solve the phenomenon that the mesh frame made in winter is easy to lose the version when printing?
Some photoresists have poor weatherability and become brittle at low temperatures. If the applied photoresist layer is thick, cracking may occur. In addition, the temperature in winter is low, the photosensitive layer is not easy to dry or insufficiently dried, and these factors will affect the adhesion of the photosensitive layer to the screen.
Solution:
1. Select a photosensitive adhesive with good weather resistance
2. Keep the operating environment temperature appropriate
3. Ensure that the photoresist layer of the template is completely dry
4. Appropriate roughening of the mesh frame
