Metal Mask is a device for printing lead on PCB by silk screen technique by forming openings on metal sheet. It is generally used in SMD manufacturing process to print lead on PCB mounted on screen printer.
Gerber Data, which is made from PCB design data, is sent to Metal Mask maker to make a production request. Gerber Data has no information about optional parts or unused material, so the quality is not uniform according to the skill of the manufacturer.
In addition, the Pad Stack on the PCB design data has only one Metal Mask shape, so it can not reflect the shape and rules of each metal mask according to various manufacturing environments.
In other words, standard metal mask management is difficult, and it depends entirely on the proficiency of the manufacturer.
Metal Mask Manager can manage each Metal Mask shape according to the standard metal mask shape of the parts and manufacturing environment. By comparing the PCB design data and BOM, unused parts and optional parts are recognized and Gerber data for metal mask making You can create.
