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
