There are regional price differences for electronic components in the world, but buying electronic components online from China may be the most cost-saving and convenient.
How to buy electronic components online from China? Plus, no minimum order quantity, all from one source, and if possible, buying all components with a BOM?
It is feasible and easy!
Buying Electronic Components Online from PCBONLINE
To buy electronic components online from China, please feel free to send an email with your BOM to PCBONLINE.
No minimum order quantity, no fake IC, and no refurbished electronic components. All electronic components come from original factories at possibly the lowest prices.
PCBONLINE, relying on its EMS factory for production, components inventory of some discontinued ST and TI models, joint procurement with large EMS, direct supply from original component factories, and bargaining power, can help you find all electronic components at one stop.
And all you need to do is to send your BOM to info@pcbonline.com.
Steps to Buy Electronic Components Online from China with a BOM
Step 1. Create A Bill of Materials (BOM)
A BOM is a sheet of all the electronic components you want. To make a BOM, you should at least include the component names, quantity, part number (PN)/manufacturer part number (MPN), and values in the sheet.
If you also want PCBONLINE to assemble the components on your PCB boards, you should also provide the reference in your BOM. (The reference is the silkscreen for the component on the PCB surface.)
Here are two BOM examples for your reference.

Step 2. Send your BOM to PCBONLINE
Go to PCBONLINE's electronic component web page, click the "Email Quote" button, and send your BOM as an attached file on the drop-out email page.
Or you can directly open your email box and send your BOM to PCBONLINE at info@pcbonline.com.
If you want PCB assembly and/or SMT stencils as well, please also send your Gerber.
Step 3. Wait for half an hour to get a quote
When you send your inquiry to PCBONLINE, the PCBONLINE team will check your BOM and get a quote to you in half an hour.
In our reply email to you, we will let you know the price and delivery time, and the unit prices and total prices for the electronic components will be contained in the BOM as an attached file.
Step 4. Confirm and complete payment
If you agree with PCBONLINE's quote, you can complete the payment by PayPal, credit card, or bank transfer to PCBONLINE's account, which will be provided to your one-on-one trade specialist from PCBONLINE.
If you want to complete the payment online, your specialist can help you do that in our online purchase system. [Temporarily, if all on your own, you can only buy PCBs on our online purchase system.]
Step 5. Receive the Electronic Components You Ordered
You will receive the electronic components upon the negotiated delivery date. If you order PCB assembly as well, you will receive the PCBAs following IPC-A-600 Class 2/3 standards in time.
You can track the quality of the electronic components by scanning the QP code on the electronic components trays or bags or tracking it on our online system.
Why Buy Electronic Components Online in China From PCBONLINE?
First of all, online electronic component purchase platforms do not manufacture but distribute electronic components.
On those platforms, you need to search for the component models and contact the suppliers one by one, which is time-wasting. And there is the minimum order quantity you have to buy for the models of the components.
To save your time, energy, and costs, and buy quality electronic components, you can ask PCBONLINE to source all of the components you want. The reasons are:
- PCBONLINE takes no benefit from electronic component sourcing services.
- Relying on hundreds of electronic components procurement points in the world, we source the best-price components.
- Free IC counterfeit detection and strict quality control of the electronic components we source.
- We can provide some discontinued ST and TI electronic components because we have some inventory.
- You can buy a tray of electronic components to try before bulky purchase. We offer a quality refund guarantee.
Why Buy Electronic Components from China
From China, you can not only find quality and cheap PCBs and assembly services but also cheap electronic components.
One reason is that in China, especially on the southeast coast, there are many original electronic components.
The other reason is that thanks to the convenient infrastructure, there is a famous electronic component market area in Shenzhen China, which is generally called "Huaqiang North", the biggest electronic component market in Asia.
Conclusion
Buying electronic components online from China is a good idea to save costs, energy, and time. Relying on an EMS factory for production, long-term cooperation with the audited and trusted local electronic component factories, bargaining power with original factories, discontinued electronic component inventory, and stable supply chains around the world, PCBONLINE can be one of the best one-stop electronic component suppliers for you.
