Production Readiness Check - Launch Initiative

All connectors are correctly oriented

Trace pinout of each connector from end to end

All connectors have silkscreen denoting which pins are which if applicable

All components have reference designators on silkscreen if possible

DNP components are not associated with a part number

All components are updated to their latest revisions

Schematic is validated and returns no errors or meaningful warnings

DRC returns ZERO errors and warnings

Certain errors and warnings may be waived with a valid reason

Acute angles are minimized

Layers are properly named

For 4 layer boards: the JLCPCB 4 layer stackup is used

Impedance Controlled Traces:

Traces have the correct impedance using JLCPCB impedance calculator (or whatever fab you are using)

Traces have transfer vias wherever a layer transition is made

Traces maintain a constant ground reference plane

All connections are teardropped when possible
