ERF Variable

Description

v_do_small_clearances

Values = Yes/No, Default = No

    Yes - compensates clearances that are smaller than their associated outer layer pads with the optimal clearance value.
 If not possible, they will be left unchanged.

    If Yes, and the original clearance is too small (i.e. the negative AR is larger than pp_opt_clearance ), the action enlarges the clearance by the size of pp_opt_clearance .

    If No, the action enlarges the clearance to achieve optimal clearance.

Usually the Solder Mask Opt action does not change small clearances, just accumulates them in the corresponding category.

Setting this variable = Yes causes the following ERF variables to be ignored:

v_grow_small_pads_pth

v_grow_small_pads_npth

v_grow_small_pads_smd

v_grow_small_pads_via
