How to buy electronic components? Directly go to a local electronic components store for spot purchase, or go online to an electronic component website to choose the components? It is okay to spot purchase only one or a few models of electronic components in small quantities. But if you are buying electronic components for PCB assembly or electronics manufacturing, you need to make a bill of materials (BOM) and purchase BOM electronic components.
BOM electronic components purchase means buying electronic components by sending a BOM to an electronic components distributor. According to the BOM, a quotation engineer gives a quote to the buyer. When the buyer confirms the order, the electronic component distributor sources, tests, and sends all the required components to the buyer.
What is a BOM?
A BOM is a datasheet of all the electronic components that you want to buy. The forms of BOMs are different and numerous, but all BOMs should contain the component quantity, reference, description, PN (part number), description, and manufacturer.
Component quantity: the number of the same electronic component for a PCB board
Reference: the silkscreen code or symbol on the PCB board surface
Description: the features of the components, including the resistance/capacitance/inductance/voltage value, tolerance, and packaging. For example, CAP 1μF 25V 0402 X5R 10pc.
PN: part number, the unique code for identification made by the component manufacturer. It can be a number series or a combination of numbers and letters. (But if you don't know the PN of the component, let it go.)
Manufacturer: the specific component manufacturer that makes the PN
A clear and comprehensive BOM enables the electronic component distributor to easily understand the customer's needs and shorten the delivery time. The editor here appeals to electronic component buyers to send such a BOM to the B2B electronic component distributor PCBONLINE at info@pcbonline.com:
