KiCADParts

A collection of KiCAD schematic symbols and component footprints which I have created / tweaked / used.

Design Constraints / Preferred Values / Conventions

  • Label size X / size Y / thickness ratio: 1 / 1 / 0.2

Eeschema

Pins:

Field reference and component name:

Part outlines:

Specify a line width of zero for the default line width (same width as the pins):

Pcbnew

  • Large component value label (size X / size Y / thickness): 0.04" / 0.04" / 0.008"
  • Common component value label (size X / size Y / thickness): 0.03" / 0.03" / 0.006"
  • Minimum component value label (size X / size Y / thickness): 0.025" / 0.025" / 0.005"

  • Outline thickness: 0.010"

Pads

  • Ratios:
  • A: Size X: 1, Size Y: 1, Offset Y: 0
  • B: Size X: 1, Size Y: 1.5, Offset Y: 0.25
  • C: Size X: 1, Size Y: 2, Offset Y: 0

0.060" nominal pads

Pads sized just under 0.060" (allows routing a 0.020" trace without violating DRC).

  • 059A: Size X: 0.059", Size Y: 0.059", Offset Y: 0
  • 059B: Size X: 0.059", Size Y: 0.0885", Offset Y: 0.01475"
  • 059C: Size X: 0.059", Size Y: 0.118", Offset Y: 0

Drill size is 0.032" (the KiCAD default), which is used for:

  • 1/4W resistors
  • small signal diodes (e.g. 1N4148)
  • ceramic and small electrolytic capacitors
  • DIP leads
  • TO-92 leads

0.070" nominal pads

Pads sized just under 0.070" (allows routing a 0.010" trace without violating DRC).

  • 069A: Size X: 0.069", Size Y: 0.069", Offset Y: 0
  • 069B: Size X: 0.069", Size Y: 0.1035", Offset Y: 0.01725"
  • 069C: Size X: 0.069", Size Y: 0.138", Offset Y: 0

Drill size is 0.040", which is used for:

  • 1/2W resistors
  • 1 Amp diodes (e.g. 1N4001)
  • TO-220 leads

0.080" nominal pads

Pads sized just under 0.080" (does not allow routing traces).

  • 079A: Size X: 0.079", Size Y: 0.079", Offset Y: 0
  • 079B: Size X: 0.079", Size Y: 0.1185", Offset Y: 0.01975"
  • 079C: Size X: 0.079", Size Y: 0.158", Offset Y: 0

Drill size is 0.056", which is used for:

  • TO-218 leads
  • TO-247 leads
  • 3 Amp diodes (e.g. 1N5401)
  • 6 Amp diodes (e.g. 6A05)

Naming Conventions

  • All files (*.lib, *.dcm, *.mod) shall be prefixed with PL_
    • e.g. PL_diodes.lib
  • All footprint names shall be suffixed with _PL
    • e.g. TO-220_PL

PL_diodes.lib

(and PL_diodes.dcm)

  • DIODE

  • SCHOTTKY

  • ZENER

PL_diodes.mod

  • DIODE_SS_059_PL
    • Small signal diode footprint
      • e.g. 1N4148, 1N5711

  • DIODE_1A_069_PL
    • 1 Amp diode footprint
      • e.g. 1N4001, 1N5817
