Metal Mask Manager
Metal Mask Manager is a tool that can register standard metal mask database, manage metal mask changing history, and check differences between design and standard metal mask.
You can change design’s metal mask according to standard metal mask. Depending on manufacturing process and products, you can manage several different metal mask databases. It means, you can import standard metal mask after reading design and check different metal masks among design, Gerber, and standard metal mask.
