The purpose of silkscreen is to prevent solder flow from one component to others.
Especially in DIP type components,this is a critical issue.
The Nearest Comp Silk dialog contains the following
sections:
Nearest Component Silkscreen Check: Check the silkscreen between two
components.
Item: Specify the item name.
Comp Group1: Select the target component group from the group
list.
Comp Group2: Select the target component group neighbor component
group from the list.
Clearance: Set the distance value between Comp Group1 and Comp
Group2.Figure 1. In Figure 1, case1 will be passed because two components are
apart and the distance is more than the given clearance value. Case2
will also be passed because there is silkscreen between the two
components. Case3 will result in a fail. They are both closely
placed and there is no silkscreen between the two components.
Other Net: Check if the two target components pins have different
net names. If the neighboring two component pins have the same net
name, PollEx DFM doesn’t check them.
