Bill of Materials (BOM):Basics
Bill Of Material(BOM) plays very important role during mass manufacturing of product though EMS(Electronic Manufacturing Service) partner or own manufacturing unit.
It contains list of components, manufacture part number, manufacture details & quantity. BOM is obtained directly from circuit.
Manufacturer's rely on this information for component procurement as well as component assembly.To manage these tremendous amount of information, companies use either Excel spreadsheets or a dedicated BOM management software's. I would like explain BOM with small circuit given below:
Reference Schematic:

Simple BOM Format:
1.If you are specific about component package,tolerance then you have to clearly mention part details from datasheet.For example lets take MCP6566. Each datasheet has details like I have given below:
2.If you are not so specific about manufacture,tolerance etc like Capacitor and Zener diode in my example then write "Any make".
