Naming Convention for Non Standard Surface Mount Device 3D Models and Footprints
Surface mount devices (SMD), which package outlines, do not belonging to IPC7351B standard are classified in Non-Standard SMD packages.
All Non-Standard SMD outline packages are divided in component categories by electrical component types (e.g. Amplifiers, Crystals, LEDs…).
Naming Convention for Non Standard SMD 3D models and land patterns (footprints) in most cases consists of abbreviation for electrical component type:
(e.g. AMP, XTAL, LED…) + _ (underscore) + Manufacturer + _ (underscore) + Manufacturer’s Part Number (Manufacturer’s Code).
Non-Standard SMD category list is shown below.
Note: All dimensions are in Metric Units and all numbers go two places past the decimal point.
