PCB Libraries Footprints - SOICs Leads

When using PCB Libraries you can easily customize your PCB Footprints.

SOIC  example:

It is not uncommon for IPC 7351 default SOICs footprints to have pads that extend under the body of the gull wing ICs as shown below,
















My contract manufacturer and SMT line expert prefers SOIC footprints with pads that do NOT extend under the body of  parts, as shown below.

PCB Libraries allows users to customize and save preferences for generating footprints. One of the settings under User Preferences > Rules is 'Minimum Trim Standoff Height'.

Out of the box the default 'Minimum Trim Standoff Height' is 0.00.  I changed this setting to 0.30 to achieve the results shown above for SOICs.

I use PCB Libraries Expert IPC-7351 footprint generator to make my PCB footprints.

That's It !
