Get a quick quote for any type of your requirements.

PCB assembly is that the PCB manufacturer takes charge the whole PCB assembly manufacturing including electronic components purchasing, manufacturing and assembly.

① Save time and money

Delegating the whole PCB assembly manufacturing projects to a turnkey PCB assembly manufacturer enables greatly save your time. In other aspect, it is beneficial to save money if we choose one-stop PCB assembly manufacturing services because we don’t need to spend time to select other services like PCB assembly testing service provider.

② Spot error in time

Adopting one-stop PCB assembly manufacturing services can effectively detect and solve the errors timely. The engineer can help make some modification on design phrase start from your customized or ordinary orders. If we cope with the errors after the whole production is completed, it will cause great cost.

③ Better monitor the process of PCB assembly manufacturing projects

Because we decide to deliver the whole PCB assembly manufacturing projects to one supplier, we don’t need to spend time to communicate with other suppliers. Once you want to make some modification or you detect some errors, you can discuss with the engineer in time, which minimizes the loss greatly.

④ Other services

Sometime, a turnkey PCB assembly manufacturing supplier also provide other services, for example the inventory and shipping arrangements. It enables greatly save your energy and money and improve your competition edge.

PCB assembly manufacturing includes many aspects. Here take a 4 layer PCB as example.

① PCB layout

Checking the PCB layout design in advance. Generally, PCB assembly manufacturing supplier would accept the demand from the customer. In this step, PCB layout design will be detected to check whether it meets the manufacturing standard and any detects may appear.

② Inner PCB layer

A layer of photosensitive film will be covered after the copper clad laminate is cleaned. This kind of film gets cure under exposing on the light, and forms a protective film on the copper foil of the CCL.

③ Drilling the core board and inspection

After the core board is completely fabricated, then we need to punch alignment holes on it for better aligning with other materials.

Once the core board is pressed with other PCB layers, it is difficult to make some modification. Thus, the inspection becomes an important part, which compare with the PCB layout design drawings through machines.

④ Lamination

Prepare uses to adhere the core board and the outer cooper foil which has insulation capabilities. Fixed the copper foil of the lower layer and two layers of prepare with the alignment hole and the iron plate of the lower layer in advance, then placed the prepared core board in the alignment hole.

⑤ Drilling

Drill holes from the top and bottom, then make the hole wall become metallizing to get conduct electricity, you can connect 4 layers copper foils together.

Locating the inner core board through X-ray drilling machine, and then making position holes on the PCB to make sure that the following drilling passes through from the center hole.

⑥ Copper chemical precipitation of the hole wall

The through hole on the PCB is for connecting different layers. In general, a 25 microns of copper film is reasonable to get connecting with other layers. This thickness needs to be electroplated.

⑦ Outer PCB layer

Make full use of photocopied film and photosensitive film to transfer the outer PCB layer to copper foil. Unlike the inner PCB layer, it adopts positive film. The photosensitive film on the PCB is cured to cover those non-circuit areas.

⑧ Outer PCB layer etching

Remove the cured photosensitive film on the PCB, then use the strong base to clean those unnecessary and covered copper foil. For those tin coating left on the copper foil should be remove through tin solution.

Selection suitable PCB assembly manufacturing technology directly impacts the manufacturing efficiency, and product quality. Two technologies are commonly used in PCB assembly manufacturing: surface mount technology and through hole technology.

Surface Mount Technology

Like some electronic products such as medical machines and smartphones, their PCB assembly manufacturing process adopt surface mount technology.

Compared with through hole technology, it allows you to process the PCB in mass with high automation efficiency.

​We offer rapid delivery, with quick-turn PCB prototypes available within 24 hours and PCBA prototypes within 2-3 days.

Yes, we adhere to strict confidentiality agreements (NDAs) to safeguard our customers' interests and foster long-term partnerships.
