SMT-Resistor¶

public defstruct SMT-Resistor <: SMT-Chip

Constructors¶

SMT-Resistor¶

Constructor for defstruct SMT-Resistor

public defn SMT-Resistor (chip-def:SMT-Chip-Def -- height:Toleranced = ?, keep-out:KeepoutCreator|False = ?, protrusion:LeadProtrusion = ?, pad-planner:PadPlanner = ?, lead-numbering:Numbering = ?, density-level:DensityLevel = ?)

Functions¶

get-resistor-pkg¶

Create a Resistor SMT Chip Package of a given size

public defn get-resistor-pkg (k:String -- keep-out:KeepoutCreator|False = ?, density-level:DensityLevel = ?) -> SMT-Resistor

k: String - Standard Package size (eg "0805") or Metric Alias (eg, "2012m")
Returns SMT-Resistor - Package with all default configurations

SMT-Chip-Def¶

SMT Chip Definition Type

public defstruct SMT-Chip-Def
    aliases: Tuple<String>
    lead-length: Toleranced
    lead-width: Toleranced
    length: Toleranced
    name: String
    width: Toleranced

aliases: Tuple<String>
lead-length: Toleranced
lead-width: Toleranced
length: Toleranced
name: String
width: Toleranced

This type encodes the parameters of a chip package such as an 0603, 0805, etc.

Constructors¶

SMT-Chip-Def¶

Constructor for defstruct SMT-Chip-Def

public defn SMT-Chip-Def (name:String, aliases:Tuple<String>, length:Toleranced, width:Toleranced, lead-length:Toleranced, lead-width:Toleranced)

Functions¶

get-chip-def¶

Get the SMT Chip definition from a case size

public defn get-chip-def (k:String) -> SMT-Chip-Def

k: String - Standard Package size (eg "0805") or Metric Alias (eg, "2012m")
Returns SMT-Chip-Def - SMT Chip Definition for this chip size if it exists.
Throws ValueError - if no chip definition with that name can be found.

SMT-Chip¶

Constructor

public defn SMT-Chip (chip-def:SMT-Chip-Def -- polarized?:True|False = ?, side-fillet:Double|False = ?, height:Toleranced = ?, keep-out:KeepoutCreator|False = ?, protrusion:LeadProtrusion = ?, pad-planner:PadPlanner = ?, lead-numbering:Numbering = ?, density-level:DensityLevel = ?)

chip-def: SMT-Chip-Def - Chip Dimensions
polarized?: True|False - Default value is false
side-fillet: Double|False - Default value is false
height: Toleranced - Default height is 0.4mm
protrusion: LeadProtrusion - The default value depends on the size of the package. If the width is greater than 0.8mm, then BigRectangularLeads is the default. Else SmallRectangularLeads is the default.
lead-numbering: Numbering - Numbering Scheme - default depends on the polarized? flag.

SMT-Chip¶

SMT 2-pin Chip Package Type

public defstruct SMT-Chip <: Package
    def: SMT-Chip-Def
    height: Toleranced
    keep-out: KeepoutCreator|False
    polarized?: True|False
    protrusion: LeadProtrusion
    side-fillet: Double|False

def: SMT-Chip-Def - Defines the Package dimensions
height: Toleranced - Z-dimension Height of the Chip Package.
keep-out: KeepoutCreator|False - Construct a Keepout underneath the component. Default is false indicating no keepout is created.
polarized?: True|False - Indicates whether to use the Anode/Cathode style pad numbering or standard p[1]/p[2] style numbering.
protrusion: LeadProtrusion - Protrusion Type
side-fillet: Double|False - Optional excess side fillet area For packages like capacitors where the lead can cover all 5 surfaces of the end of the package, this parameter provides excess pad area to allow the wetted solder to fillet on the side of the contact. This value will be added to both sides of the pad. This will increase its total width by 2.0 * side-fillet. If false, then no excess side-fillet area is added.

This type is used to define the packages for common SMT passive components like resistors, capacitors, etc. These packages are typically named 0603, 0805, etc.

Returns SMT-Chip - SMT Chip Package with all default configurations
Throws ValueError - if no chip definition with that name can be found.

chips¶

SMT Chip Table

public val chips

This value contains a lookup table for the different SMT definitions read from the SMT Table. The keys of this table will be in the form 0603 or 1608m where the m suffix indicates the metric variant. There are also Wide * name variants in this table.
