· Control criteria |
|
Screen dot situation |
Mask surface should be uniform and free from defects and dirt |
|
Dot loss |
Continuous loss must be less than 3 dots, less than 2 dots loss in a bumping, and less than 3 dots loss in a mask. |
|
Dot connection |
Continuous connection must be less than four dots, less than 2 dots loss in a bumping, and less than 3 dots loss in a mask. |
|
Line Defects |
1) Convex block with visual apparent defects or scratch can be discounted or refused to accept. 2) Left glue on edge node or broken dots must be less than 2 lines. |
|
Bubbles |
Phi is allowed within 0.5 mm, and the screen dot is without damage. |
|
Stains and spots |
Without stains or spots on surface; with very few but can be erased. |
