·         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.
