We use customers libraries.
We can build components from customer requirements or maybe use our own standard IPC library.
Library Expert Pro, LP Wizard or IPC® Compliant Footprint Wizard in Altium Designer are the tools we use for generating the IPC components.
If possible, we apply a 3D model of the component instead of the auto generated model, which typically only is a box.
