the IPC registered land pattern dimensions.) The dimensions for the statistical minimum and maximum sol- der joint fillets at the toe, heel, or side (JT, JH, or JS) . The answer provided by asndre refers to three levels of density for laying out PCBs, which are referred to in IPC (original, B and long-awaited C) as Levels. IPCB Naming Convention for Surface Mount Device 3D Models and Footprints. The 3D CAD solid electronic modes/footprint (land pattern) naming.

The PSON Footprint Dimensions page displays the inferred footprint dimensions using the package dimensions previously defined. A solder joint may be described by three fillets: Top leftBottom leftBottom rightor Top right.
Enter the required values for the package pin dimensions on the ChipArray Package Pin Dimensions page. You can further define the silkscreen dimensions by entering a new value for the Silkscreen Line Width. Use the drop down to select the correct Package Type: You can change the values for Fabrication Tolerance AssumptionPlacement 751 Assumptionand Courtyard Excess by entering the new values directly in the textboxes.
Use the drop-down to select the Package Type: The DFN Footprint Dimensions page displays the inferred footprint dimensions using the package dimensions previously defined.

You can download a free Altium Designer Viewer license which is valid for a 6 months. A component body contains the volumetric information corresponding to the package dimensions. Solder fillet refers to the shape of the solder joint between the component lead and the PCB pad. Rather than working from footprint dimensions, the IPC Ipx Footprint Wizard uses dimensional information from the component itself in accordance with the standards released by the IPC.
The DPAK Footprint Dimensions page displays the inferred footprint dimensions using the package dimensions previously defined.

Producibility Levels When appropriate iipc standard will provide three design producibility levels of features, tolerances, measurements, assembly, testing Enable the Add Courtyard Information and Add Assembly Information to add courtyard and assembly information to the component drawing.
We have the perfect program for you. Choosing the Footprint Name and Description The Footprint Description page is used to name and describe your new footprint. Minimum values for solder fillets at the toe, heel and side of the component icp have been determined by IPC based on industry empirical knowledge and reliability testing.
