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.\ ![Remove order number options](/assets/img/2024-02-18-PCB-manufacturing-ch/order-number.png) - [ ] 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.\ ![Impedance stackup](/assets/img/2024-02-18-PCB-manufacturing-ch/stackup.png) ### 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.
