1. The tension of the screen printing screen is very important for suitable photosensitive adhesive coating. If the tension of the screen is too small, the screen is too loose, causing the pressure of the gluer on the edge of the screen to be greater than the center of the screen. The photosensitive coating is thicker at the center of the screen, while the coating at the edges of the screen is thinner. Mingde screen printing reminds you: screen tension should be well controlled
2. The pressure of the squeegee must also be appropriate. If the pressure exerted by the squeegee on the screen is uneven during the squeegee stroke, only holding the squeegee with one hand will often lead to a problem. Gluing the gluer is to use two hands to operate and clamp the frame to the fixture. Mingde screen printing factory reminds you: the squeegee force should be uniform
3. If the size of the squeegee is too long relative to the screen frame, the two sections of the squeegee walk on the edge of the screen frame, which will reduce the pressure of the squeegee and cause uneven coating. The length should be 5-10cm less than the size of the coated screen. Mingde screen printing reminds you: use the size of the squeegee reasonably.
The following are the standards that stencil production needs to meet
Dimensional accuracy of outer frame: ±0.3mm external tolerance ±0.3mm, normal negative tolerance
Adhesive thickness range: 0.05~0.17mm; 0.05/0.1/0.13/0.15/0.17mm
Minimum line width: 0.2mm printing line width should be larger than 0.2mm as much as possible, and the minimum should not be less than 0.2mm
Minimum gap: 0.3mm The printing gap should be as large as 0.3mm, and the minimum should not be less than 0.3mm
