Cost effective & accurate quotation based on BOM
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.
Although there are many online BOM tools, they also cost your time and have high requirements of your experience and profession in electronic industry. Now at Runrays, free comfortable! You only need to pass the complete BOM of electronic components to us. Generally in 2-12 hours, Runrays can get back to you with ACCURATE QUOTATION.
By the way, in order to expedite the quote making, following key fields should be included in BOM.
- Manufacturer: the specific component manufacturer that makes the PN
- Part number: the unique code for identification made by the component manufacturer.
- Description (optional): the features of the components, including the resistance/capacitance/inductance/voltage value, tolerance, and packaging. For example, CAP 1μF 25V 0402 X5R 10pc.
- Quantity: the number of the same electronic component for a PCB board
- Reference (or Designator): the silkscreen code or symbol on the PCB board surface
