Quality check methods include a film thickness gauge, tape to check adhesion, and a cross-cut test using a test piece.

The appearance is visually checked for color, dust, spots, dimples, etc. by referring to a defect size estimation chart. Screws are used to check the functionality of tapped holes.

To clean, wipe with water and a soft cloth or sponge, or wipe with a diluted neutral detergent, then wipe with water, then wipe dry. Please refrain from using alcohol and petroleum solvents such as thinner, benzene, etc.
