various check lists to avoid screwing up electronic manufacturing projects ====== before designing ====== parts: * ensure you have enough parts locally * prefer parts with high availability and multiple distributors ====== after designing ====== schematic: * BOM: put part ordering information, or use description for generic parts board: * run rats nest to ensure all is connected * run DRC * ensure non-plated through hole (e.g. mounting hole) have copper clearance (else it will be manufactured as plated hole) * ensure outline is present and uses 0.1 mm lines * ensure the text next to the LEDs, header pins, and test points are the right ones * remove floating trace stubs (disable pad/subcircuit visibility, and show planes as wireframe) * place project/board name and version * place ordering number text under a component, or on panel rails * place reference designators for assembly * check solder mask (e.g. tented holes) and solder paste (e.g. through hole pins) * check outline copper pullback * check output gerbers * print gerber and place components to check footprints (particularly if new) and spacing
