Pin Count Mark

Check the existence of a pin counting mark and the interval around certain components.

The Pin Count Mark dialog contains the following sections:

Target Component Definition: Set the checking target component and its layer.
- Component Group Selection: Select the target components from predefined component group list.
- Minimum Number of Pins: To select target components, specify the minimum number of pins.
- Pin Counting Mark Existing Layer Definition: Select pin mark existing layers for top and bottom.
  - Top Mark Layer: Select the top pin counting mark layer from the layer list.
  - Bottom Mark Layer: Select the bottom pin counting mark layer from the layer list.
Checking
- Interval (Number of Pin’s Repeating): Set the pin interval. For pins, there should be a pin counting mark for every given number of pin interval. Otherwise, it results in fail.
