Mask pattern


The figure below is the one to have expanded the actual mask pattern by twice.
This time, in the way of my introducing, the mask pattern of the actual size must be used.
The small part has been distorted when changing the mask pattern of the actual size into JPG and the GIF.
Therefore, the mask pattern of this page expanded by twice.

In the page of "Process of the Printed Circuit Board making", I publishe the file by Visio.
The person who is installing Visio in the PC can use.
When printing with the printer, specify the print by the best quality.
The condition of the mask pattern influences the finish of the printed circuit board directly.
