Makerfabs One-stop PCB Assembly Service

PCB & PCBA at Makerfabs

What's PCB and PCBA?
PCB(Printed Circuit Board) is a conductive pattern formed on conductive material according to the engineers’ design, there only traces/holes/layer on it, but without any components installed; While the PCBA(PCB+ Assembly) means bare PCB board assembled with components such as resistors/ capacitors/ IC, to make the whole circuit board works as intended. After the PCB was designed, the files can be sent to PCB factories for production. Meanwhile, after components sourced, and then installed on the PCB, and finally programming, testing…

But this is not actually an easy work, especially for a maker & startup, there're many processes to create a working PCBA board…

Makerfabs provides the turkey PCBA service from PCB production, components sourcing, PCB assembly, soldering, programming, testing to end shipping. With this service, the electronic designers do not need to suffer from these very detailed works such as soldering the prototype board, and thus can concentrate on the creating and designing works.

1. The PCB Materials: FR4/FPC/Aluminum/Rogers…

There're many kinds of PCBs, vary from the board materials, mainly:
  1. FR4: The most common used Material for PCB.
  2. FPC: Flexible Printed Circuit is a thin insulating polymer film that conductive circuit patterns are printed on, the most advantage for FPC is flexibility, which allows it to be the connection within a compact space or parts that need to bent. Also check the differences between Rigid-flex PCB and Flex PCB with stiffener.
  3. Aluminum board: The Aluminum PCB has good heat dissipation than FR4 PCB, which makes it suitable for boards that need quick/large heat dissipation, such as the LED Boards.
  4. Rogers: When advanced electrical properties and performance are critical, such as Dielectric, dielectric constant, Rogers PCB boards would be the solution, normally only for Professional high-frequency electronic engineers.

As the specs for FPC/Aluminum/Rogers PCB, is very complex and hard to list the details, please contact your project manager or service@makerfabs.com for detailed info and Spec/ Productivity checking.
 

2. Make a PCB order

If only bare PCBs needed, there're many PCB online shops, that can make you complete a PCB order in 2 minutes. In Makerfabs, you can:
  • Fulfill the PCB specs and input the Gerber files at the PCB prototyping page, at Makerfabs->PCB Prototyping.
                                                 Makerfabs PCB Prototyping service
  • Checking out, with PayPal.
  • Waiting for your PCBs arrival, total lead time less than 1 week.
Of course, for complex PCBs, and special requests, it would be easier contacting your project manager or service@makerfabs.com to check and quote for you.
 

3. Makerfabs PCBA (Printed Circuit Board Assembly) Service/ PCB Assembly Service

Makerfabs PCBA Service
If a fully assembled PCBA needed, few steps to Order PCBA from Makerfabs:
1. Send your request to sales@makerfabs.com or service@makerfabs.com for a quotation. For PCB Assembly work, please send us:
  • PCB Gerber Files(RS-274X), and the specs such as color/ pads finish/ layers, etc.
  • BOM Files, some reference links or Digikey/ Farnell parts number would be helpful for our quotation. Check the 5 Tips In BOM When Asking PCB Assembly Price Estimate.
  • Files for the Soldering such as parts mapping for the pick-n-place machine, or a simple mapping for hand soldering. (Check 5 Common Problems In PCBA Manual Soldering if you have trouble in manual soldering.)
  • Programming/ Testing Method, Makerfabs will help to test all the PCBA boards to ensure you 100% pass.
  • Other Files that you want us to know to avoid mistakes in the production.
2. Makerfabs will make you a quotation in 1 working day. 
3. Customers checking on the quotation and confirmation, and negotiation if needed. Refer the How To Check The PCBA Quote From Shenzhen PCBA Factory.
4. Makerfabs works on your project and PCBA in production.
5. Packing and Shipping, customer’s checking and feedback, then projects closed if all OK.

  • Components: Makerfabs cooperated with the official components distributor, or Mouser/ Digikey/ Farnell, to avoid bad/ fate components. For electronic components that substitute brands will be used, normally for resistors/capacitors/connectors, Makerfabs will mark them in the quotation sheet, let the customer know the detailed components used. All components will be double tested before the soldering:
