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.
