A list of things to check before putting a board into production. Update this list as fails occurs.

Pre-ordering

  • Put JLCJLCJLCJLC text on the PCB to ensure the order number is placed in a hidden location under a connector, large component, etc.

PCB ordering

Ordering

  • Select "Specify a location" for remove order number to ensure the the JLCJLCJLCJLC text is replaced with the order number.

  • Make sure expensive items/option parts not meant for assembly are not placed down/autodetected by JLCPCB's parts catalog (you should use the variants system to ensure this cannot happen).
  • Check the orientation of each IC and diode in the PCBA list. For each item, make a note that it has been checked/corrected.
  • Check if impedance control is needed. Select JLC04161H-7628 for standard impedance control stackup.

Checkout

  • Make sure to use the coupon for free PCBA setup.

Ordering separate parts from Mouser/Digikey

Take a risk-adverse approach since ordering individual parts is expensive with shipping fees.

  • Create variant for parts used in JLC and parts which need to be ordered separately. Double check the BOM and order extras of critical components.
