how much does it cost to get a pcb assembled?

The PCB assembly cost may be from 1USD/Pieces to 100USD/pieces. The pcb assembly cost can be so far different is because different design pcb board may would involve different material, equipment and labor cost.

There are several factors affect PCB assembly cost: using components, assembly methods, PCB complexity.

  • The PCB assembly involve more electronic components, the cost would be higher. Some electronic components are pretty expensive, such as FPGAs and ICs, if PCB assembly need to use them, price would be expensive.
  • The machine automatic assembly is more precision and stable than manual, but it is costly, if quantity is small. Manual assembly would easy make more scraps.
  • The more pcb complex, the pcb assembly cost is more expensive. Usually Rigid-flex, high frequent, HDI, multilayer PCBs are expensive. If the PCB is with special design such as Microvias, blind vias, buried vias, the pcb would be more expensive. Also fine-pitch would consume more cost.
  • Lead free PCB assembly would use soldering machine work in high temperatures than lead pcb assembly, so if you make lead free pcb assembly you would spend more.


why is pcb assembly so expensive?

Usually people may found their the pcb Assembly cost is far expensive than bard PCB, They would confuse, why pcb assembly service so costly. Are those PCB Assembly manufacturer quotation reasonable?

If you want to know the manufacturer quotation fair or not, you should know the factors affect pcb assembly cost first. The factors affect the pcb assembly price are a lot, such as turnaround time, lead-free assembly or not,  BGA components, fine pitch, lead less, quantity of THT,  double-sided SMT  or not, quantity of PCBs,  BOM lines etc.

Some unused components should be abandoned, that can save time cost. Different project should select correct soldering method. If some cross reference part cost is cheaper, you can take it into consideration, that would help you save cost. Our team can give some suggestion on this part for customer reference free of charge. Fine pitch parts and lead free standard requirement would consume more cost. if your project can give them, you can save cost. You can think it careful before make decision.

If your PCB assembly is double sided assembly, you would spend more cost. Becuse placing electronic components on PCB two side surface, at least you need to two time, and stencil you need to make two side stencil, machine programming work also need to make two times. so compare with single side Assembly it must take your more cost.

Is there leadless and fine pitch requirement on your PCB assembly project, if yes, they would consume your more cost too.

If your project is urgent, you request quick turn around pcb assembly service, that would consume your more cost. This is same condition in all manufacturer in the world.

If you don’t know which parts you can save, you can contact us, let us evaluate your project and give you some professional suggestion for your reference first.

how do i order a pcb assembly?

what is the difference between pcb assembly and pcb fabrication?

PCB fabrication is to manufacturing bare PCB board, BCB assembly is used bare PCB to solder electronic components on bare PCB board.

PCB assembly

When a pcb board want to performance its electrical function in product, it need to solder with a lot of different electronic component on the bare board. The process of soldering electronic components on blank bare board is called PCB assembly. Use there is two way for PCB assembly, one is surface mount technology(SMT) assembly, other is through hole technology(THT) assembly.

SMT assembly is printing the soldering pasted by metal stencil on PCB, and use automatic machine to pick and place electronic components on the PCB.

Through hole technology assembly is used the electronic components lead to insert into PCB holes and solder on the PCB board.

PCB fabrication

The process starts with a design. Some PCB fabrication specialists use a client’s Gerber file as the basis for a board. This file describes the physical characteristics of the board and its intended use. Other customers provide their own files, which the PCB manufacturer then uses to generate schematics. These files are then rendered in an industry-standard format. A PCB can be fabricated from a Gerber file if it follows the correct specifications and is created using a certain standard.

There’s a process for building PCBs, which begins with design and layout. Next, cutting and lamination take place. This is just one step in the manufacturing process. It adds up to laying images and drying devices on the board. The final step is soldering the entire board to the core. After the PCB is assembled, it’s time to test it!

some question about pcb assembly below you interested in:

1. If we receive your pcb assembly boards with defects? How you handle our problem?

We know the quality is our company foundation base, so we take quality seriously.Usually we would test all the PCB board before shipping, any defective PCB found would be take out from the batch, only the perfect PCB can be shipping out to customers.

If you still receive the PCB assembly with defective, you can take the photo or record the video and send back to us, we would ask our engineers to analyse what is the problem. If the defective is our quality problem, we would resend new perfect PCB board to you free of charge.

2. What components you would use for PCB assembly, are they quality good?

Our components usually come from element14,digikey,mouser, local electronic market. If you think any market components is better, tell us, we can go to buy components from those market and control quality for you.

3. Can you keep our pcb assembly project information secure?

Yes, we wouldn’t disclose your project information to any other one, we would keep it secretive, between you and us.

4. If I conact you, how long you can quote back to us?

As long as contact with us, and send your project detail documents of your pcb assembly to us, we would quote back you within 12 hours. With cost and lead time.

5. Can you buy electronic components from the our specified supplier?

Yes, we can buy the electronic components for your awarded supplier. If you need, we also can pay for them and arrange the delivery components from them to us, all work we can do for you. Let your work be easier.

6. Does your quotation of PCB assembly in a detail quotation sheet?

Yes, we would arrange a quotation excel for you, which include each parts, components and labor cost for you, let you know about their cost exactly.

7. Is your PCBs assembly ROHS quality?

Yes, all our materials are lead free. We export a lot of PCB board to German, Italy, Sweden, UK etc.

8. What is your minimum quantity order ?

We don’t have quantity limited, one pieces pcb assembly, we also can make for you.
