The following is an introduction to the production methods and techniques of PCB circuit board silk screen printing.
1. Stretch the screen
Steps for stretching the screen: cleaning the screen frame → level inspection → applying the base layer of glue → stretching the screen → measuring the tension → applying glue → removing the screen, sealing the edges → storage.
Job description:
1. Due to the repeated use of the screen frame, residual adhesive, net yarn, and other debris may accumulate around it. This must be cleaned to ensure proper adhesion between the net yarn and the screen frame.
2. Place the screen frame on a level platform to check for any deformation. If deformation is present, it must be corrected to ensure proper alignment.
3. After cleaning, the undeformed screen frame and net yarn are spread out. A layer of glue without hardener is evenly applied to enhance the adhesion between the net yarn and the screen frame during the drawing process.
4. Approximately 10 minutes after the initial application of glue, position the screen frame on the drawing table and adjust its relative position and height as needed.
