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, 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), 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. (reference is the silkscreen for the component on the PCB surface.)

Here are two BOM examples for your reference.

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 per prices and total prices for the electronic components will be contained in the BOM as an attached file to you.

Note
If you also send a Gerber file and a BOM for your PCB, PCBONLINE's solution experts will check both and make sure the feasibility of your project. If there's some problem, we will give improvement suggestions to you for free.

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, the 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, 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 to 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 of 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, as well as stable supply chains around the world, PCBONLINE can be one of the best one-stop electronic component suppliers for you.
