Many electrical engineer ignores to build a standard BOM (Bill of Materials), which will make PCBA manufacturer confused during translating design files to manufacturing files (internal use). Most importantly, any discrepancy between manufacturer and designer will induce serious faults and rework on produced circuit boards.
Therefore, what's the best standard BOM in perspective of PCBA manufacturer? The BOM should include following items:
Part manufacturer
Part number (detailed)
Key specifications
Quantity
Designators
Other remark
Here is a BOM template for your reference.
