2) Teaching example of representative component
- Draw soldering inspection window in wave solder area and select wave solder to
automatically create green circle and red rectangle.
- Green circle is to inspect solder area, and red rectangle is area to inspect pin or lead
exposure.
- White dotted line circle in the center is a virtual area that does not actually appears, and it
