Adjust Solder Mask Expansion from PCBLIB Inspector

tomridl

Hi,

 

I am trying to adjust the solder mask expansion value from the PCBLIB Inspector, but there is only a checkbox to for "Solder Mask Override", and then no where to enter the override value. This means that to adjust the solder mask expansion, you have to manually change it for every pin instead of for all pins at once. Please could you add the option to adjust this for all the selected pins in the inspector, as per full Altium. Bit of a mission changing 100 pins manually! Does anyone know of another way to do this without using the inspector?

 

Thanks

    Hi Thomas, you can set the solder mask expansion in the PCB editor using Home > Design Rules; Mask > Solder Mask Expansion rule set. The override option is typically used when you need to set a few special pins with a different value to the rules you have defined.

    Hi Peter, thanks for the reply.

     

    This will then change the solder mask expansion for all components (which I don't want to do). If I have only one fine pitch component that needs to be different to the default, then it seems I have to do each pin manually. It seems strange that there is a checkbox in the PCBLIB Inspector to override the default, but no place to enter in the override value!

    If there is one specific component then you can add a design rules to set a different expansion and apply the rule to either a named component (ref des) or footprint.If you are trying to set up in the library editor you can set the properties for a pad to specify a mask expansion value using the radio button and then entering a value (see image).

    I can remember, that in Altium you had an option to adjust the value from the PCB inspector and was looking for the same in CircuitStudio, but as you say, that option has been removed. I did a fast google search and found a screenshot from Altium. Also made a screenshot from the inspector in CS. It is kind of annoying how specific features are randomly removed in CS!

    But as mentioned above you can define rules for specific pads. How I currently do it: In the PCB go to "Classes" --> Create a "Pad class" and add the pads to the class for which you want to have a specific mask. --> Create a new "Mask" rule with higher priority and chose "Where the object matches" "Pad class" --> Your pad class.

    The override was in earlier versions of CS. Might be bug?
