+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.\
+       ![](/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.
+
+### 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.
