BOM(bill of materials), a simple definition, "records the product composition required to use the bill of materials". It is not only a technical document, but also a management document. In the production process of PCB copy board, the production of BOM list is a key link, which involves the subsequent purchase of components, various functional modules of PCB board, as well as the welding and debugging of the final PCB clone board. Since this list includes all the relevant parameters and specifications for all components of the original PCB board, it is an important part of the replica board and design. In general, BOM tables are used to purchase components during model cloning. Only electronic components purchased from the BOM list can be accurately soldered to the PCB to complete the whole PCB cloning process.
BOM form specific application:
1, is the basis for computer identification materials.
2, is the basis for the preparation of the plan.
3, is the basis of supporting and picking.
4, according to its processing process tracking.
5, is the basis for procurement and outsourcing.
6, according to its cost calculation.
7, can be used as a quote reference.
8, for material traceability.
9, so that the design series, standardization, generalization.
