PCB screen printing production process is divided into two main aspects: mesh stretching and mesh drying.
There are various detailed operation methods involved in these steps, let’s explore them together below.
Pulling The Net Steps involved in pulling the net include: cleaning the screen frame, inspecting for levelness, applying bottom layer adhesive, stretching the mesh, tension measurement, applying adhesive, removing the mesh, sealing the edges, and storage.
Here are specific operational instructions:
1. Clean the screen frame thoroughly to remove any residual adhesive, debris, or yarn that may affect the adhesion between the mesh and the frame.
2. Place the screen frame on a level platform and check for any deformation that needs to be corrected.
3. Apply a layer of Nanbao right grease evenly on the undeformed screen frame and mesh to enhance adhesion during the stretching process.
4. After the initial glue application, position the screen frame on the stretching table and adjust accordingly.
5. Select the appropriate mesh size, spread it on the frame, and securely clamp it without any wrinkles. Ensure all corners are properly secured.
6. Gradually stretch the mesh to the specified tension levels, allowing time for the tension to stabilize at each interval.
7. Apply adhesive to the mesh and frame surface, making sure to avoid excess glue in the center of the screen.
8. Once the adhesive is dry, trim the excess mesh, label the screen with relevant information, seal the inner corners with red glue, and use waterproof tape to further secure the frame and mesh.
Following these steps will ensure a successful PCB screen printing production process.
