    PCB Footprint Expert Naming Convention Notes

    All dimensions are in Metric Units All Lead Span and Height numbers go two places past the decimal point and include trailing Zeros All Lead Span and Body Sizes go two place before the decimal point and remove leading Zeros All Chip Component Body Sizes are one place to each side of the decimal point Pitch Values are two places to the right & left of decimal point with no leading Zeros but include trailing zeros

    Naming Convention Special Character Use for Footprints

    The _ (underscore) is the separator between pin qty. in Hidden & Deleted pin components and to append modifiers at the endThe (dash) is used to separate the pin qty.The X (capital letter X) is used instead of the word by to separate two numbers such as height X width like Quad Packages.

    Suffix Naming Convention for Footprints

    Common SMT Land Pattern to Describe Environment Use (This is the last character in every name)Note: This excludes the BGA component family as they only come in the Nominal Environment Condition

    M ................. Most Material Condition (Level A) N.................. Nominal Material Condition (Level B)

    L.................. Least Material Condition (Level C)

    Components that have different Thermal Tab sizes, different Lead Tolerances or different BGA Ball Diameters

    Thermal Tab Examples for QFN, PQFN, SON, PSON, SOP and QFP w/Thermal Tabs: QFN50P600X600X100-41T365 = Thermal Tab size is 3.65 mm square QFN50P600X600X100-41T365X200 = Thermal Tab size is 3.65 mm X 2.00 mm rectangular

    Lead Tolerance Examples for Gull Wing Lead pkg. and QFN & SON that need additional differentiators: SOP65P490X110-8L20 = Lead Terminal has a 0.20 mm Tolerance

    BGA Ball Size Examples to add an additional differentiator to eliminate duplication: BGA100C80P10X10_900X900X150B43 = Ball size is 0.43 mm nominal

    Components with Hidden, Deleted or Reversed pins

    Reverse Pin Order (or Mirrored Part) -20RN.......... 20 pin part, Reverse Pin Order, Nominal Environment

    Hidden Pins -20_24N ...... 20 pin part in a 24 pin package. The pins are numbered 1 24 the hidden pins are skipped. The schematic

    symbol displays up to 24 pins.

    Deleted Pins -24_20N ...... 20 pin part in a 24 pin package. The pins are numbered 1 20. The schematic symbol displays 20 pins.
