Screen printing mesh are used in many industries now. Various problems are often encountered in use. For example, the cause of the uneven photosensitive layer.
The reasons for the uneven photoresist layer are mainly the following:
1. If the size of the scraper relative to the screen frame is too long, the two sections of the scraper walk on the edge of the screen frame. The length should be 5-10cm less than the size of the coated screen.
2. The screen printing mesh tension is very important for proper photoresist coating. If the screen printing tension is too small and the screen is too loose, the pressure of the applicator on the screen edge will be greater than the screen center, which will cause The photosensitive coating at the center of the screen is thicker, while the coating at the edges of the screen is thinner. Mingde silk screen prompts you: the screen tension should be well controlled.
3. The pressure of the scraper must also be appropriate. If the pressure applied by the scraper to the screen is uneven during the scraping stroke, holding the scraper with only one hand will often cause a problem. The glue applicator is operated with two hands and clamps the net frame on the fixed installation. The silk screen factory of Mingde reminds you that the scraping strength should be uniform.
