1.1. Writing uses C-style naming with the first letter of each word being capitalized. Ex: "Socket_Strip_Straight_2x06"
1.2. Every acronym has all of its letters capitalized.
1.3. Manufacturer name is capitalized as usual. Ex: NEC, Microchip
1.4. Component name must match its filename
1.5. When dimensions are used in part name, they are in millimeters, decimal places separated by a dot, and unit is not capitalized. Ex: "Cap_10x13mm_RM5"
1.6. Filename is the same as the part name.
1.7. The Value field must be prefilled with the object name.
1.8. The order of elements in names must be the same as the enumerations presented in this document.

4. Symbol Names
---------------
TODO
4.1. Name of symbol, may be shortened for common components or use reference designator of the symbol (IEEE 315-1975). ex: "Conn_4x2", "C"etc.
4.2. Manufacturer.
4.3. Part number, including extension for specific footprint. (JEDEC for common devices, ex: 1N4001)
4.4. Any modification to the original footprint, indicated by appending the reason. Ex: different pin ordering: "transistor_PNP_pinswap1"
4.5. Indication of quantity if symbol is an array. ex: resistor array: "Resistor_x8"

6.4. For surface-mount devices, origin is placed in the middle with respect to device lead ends (IPC-7351).
6.5. Silkscreen is not superposed to pads, is completely visible after board assembly, uses 0.15mm line width and provides a reference mark for pin 1. (IPC-7351)
6.6. Cannot be duplicated to match a different pin ordering. This is to be handled in the symbol libraries.
6.7. Footprint name must match its filename (.kicad_mod files)
7. Names for footprints of Surface-Mount Devices (SMD)
