# AISLER custom DRC rules.
# Make Hardware less Hard. 
#----------------------------------------------------------------------------------------------------
# We created these custom rules to warn you if your design hits our manufacturing bounderies. 
# You can disable the custom rules by commenting them out, though we advise against it.  
# These rules are valid as of May 2024, please check for updated ones on our forum.
# Please also note that these rules do not catch every single manufacturing limit. 
# If you are not certain please check the documentation on our website.

# As our tooling is finite we only support certain trough hole sizes. 
# Please keep the plated trough holes below 5.6mm in diameter. 
# We provide a community post for more details: 
# https://community.aisler.net/t/plated-and-non-plated-holes/50

(rule "Max Drill Hole Size PTH"
    (constraint hole_size (max 5.6mm))
    (condition "A.Pad_Type == 'Through-hole'"))

#----------------------------------------------------------------------------------------------------
# We dont support micro or buried vias

(rule "Disallow buried via"
   (constraint disallow buried_via))

(rule "Disallow micro via"
   (constraint disallow micro_via))

#----------------------------------------------------------------------------------------------------
# The Soldermask is pulled back by a bit to account for slight missalignment during manufacturing. 
# We do this on our own, please keep the soldermask margin set to 0.
