Locate JLC Order number on PCB

  • To indicate the location, simply add the text "JLCJLCJLCJLC" to the silk layer and select the "Specify a location" option when placing your order.
  • Please note that if this option is not chosen, we may not notice that you have added the text.
  • Note: Use only "JLCJLCJLCJLC" without any additional characters.
  • The font size should be larger than 0.8mm in height and 0.15mm in width.

Notes on Running KiCad

Some misc. stuff

Custom BOM Python Script (KiCad 6)

  • Create a BOM that requires minimal manual editing to use on MediaWiki webpage
  • Adds Datasheet path to Description
  • Creates BOM .csv file in the folder where the schematic is located

Source Code

Running

  • Add links to schematic parts

KiCad BOM DatasheetLinks.png

  • Run BOM tool inside schematic

  • Click Generate

Post-Processing

  • Edit in spreadsheet program
  • Use pyCSVtoMWTable to create MediaWiki format output

JLCPCB Lot Number

  • The location of the JLCPCB Lot Number can be manually placed
  • You can indicate this location by adding the text of " JLCJLCJLCJLC" to silk layer, and select the "Specify a location" option when you place an order. If this option hasn't been chosen, we may not notice you've added the text.

Note: Just "JLCJLCJLCJLC", No more or less characters. The font size should be larger than 0.8mm in height and 0.15 mm in width.

  • If you choose Panel by JLCPCB option when you place your order, then we will add the order number on the tooling strip by default, so there is no serial number on your product PCB.

SPICE Simulation

Create Footprints Using FreeCAD

  • Our very simple example

"Standard" Footprints

  • KiCad footprints can be a pain so this documents the footprints we commonly use

  • KiCad v6 footprint

  • Also fits 1/4W resistors with leads bent straight down

ZIF Socket

  • Big rectangular pins
  • Too big for "standard" DIP holes
  • A lot of pushing can get the socket
  • Squeezable pins vertically
  • Measures at 0.033" wide, 0.017" tall
  • Standard plated hole 0.0315" (0.8mm)
  • Make hole oval
    • 1.2mm x 8mm (0.047" x 0.033")
