Turnkey PCB Assembly - Process and Tech Specs


Tech Specifications

In PCBONLINE, you can get turnkey PCB service including PCB manufacturing, PCB assembly, components, packaging and delivery. If you request we can also assemble the final products for you. You can find out our tech specifications as below.

  • PCB manufacturing

  • Types: MPCB (aluminum and copper based boards), flexible, rigid-flex, HDI, multilayer, high frequency, high-TG, ceramic, carbon, carbon nanotube, lead-free, halogen-free, LED, etc.

    Layers: 1 to 100 layers

    Quantity: 5 to 10,000+ pieces (any quantity as you requested).

    Lead time: as short as one working day (depends on the complexity of the boards but we are the fastest in the market).

  • PCB assembly

    Techniques: SMT, THT, and mixed type (all compliant with RoHS and ISO9001-2015) Tests: test of manufacturing, 3DSPI, in-circuit test, X-ray, functional circuit test, automatic optical inspection, flying probe test, etc. (full tests are applied to ensure quality).

    Volume: low volume assembly (5-2,000 pieces), medium volume assembly (2,001-10,000 pieces), and high volume assembly (10,000+ pieces)

    Lead time: as short as 8 hours (depends on the complexity of the boards but we are the fastest in the market).

  • Component sourcing

    Components: we source all kinds of RoHS certified components, including battery, resistors, LED, transistor, capacitors, inductors, diode, switch, etc.

    Sources: direct sourcing from component factories > cooperate with component factories and get authorization > sourcing from direct factory agents > buy from normal channels such as Digi-Key and Mouser (the priorities decrease as we want to source electronic parts at the lowest price and make sure quality).

  • PCB design (if you request)

    PCBONLINE has hundreds of experienced engineers and we can easily help design PCB layout for you if you require. You can get to know how we can meet your request from the table as below.


EMS Service Process

Turnkey PCB assembly is a kind of EMS (electronic manufacturing services) service provided by PCBONLINE, which manufactures end electronic products or parts of a product of our clients'. The process of our turnkey PCB assembly service is as below when you order from us.

  • Step 1. PCB manufacturing

    When getting the Gerber files, drill files, and BOM from you, we check them immediately and then give a quotation to you in a quick manner. When you confirm, we start to manufacture the PCBs. If you don't have a Gerber file but only your requirements, we can also produce the PCBs meeting your requirements. PCBONLINE can fabricate all circuit boards for any circuits, but we are featured with the advanced boards. You can order from us without a minimum circuit board quantity limit, and no matter what your requirements are, we can manufacture your PCBs.

  • Step 2. Component sourcing

    We provide all the components in your bill of materials (BOM), including passive components, active components, and custom-made special components. Component sourcing happens simultaneously when we manufacture the PCBs to save time. We have 21 years of PCB manufacturing and component sourcing experience, and we ensure that all components are of the best quality. All the components are high-quality and traceable. Our component warehouse is next to the PCB assembly factory, so we can mount the circuit board parts immediately once we test the component functionality.

  • Step 3. PCB assembly

    When the PCBs and components are ready, PCBONLINE will mount the components on the circuit boards. Our assembly includes the SMT assembly and THT assembly, and we manufacture the SMT stencils for the assembly. Our assembly machines are advanced, such as the 3D SPI, reflow soldering ovens that can deal with both the lead-free and lead-containing soldering, 3D AOI, first piece tester, and more. The whole operations and solder paste we provide are also RoHS-certified, and you don't need to worry about the assembly quality. After the assembly, the PCBA functional test and burn-in test are processed to ensure circuit board quality. You can also require any other tests or measurements like spraying three-anti paint.

  • Step 4. Final assembly

    Our EMS service includes the end product assembly, and all you need to provide is only the drawings of the product shell and package. We will manufacture the product shells, assemble the end products, print the electronic product codes, and package them. The packaging includes the instruction, inner packaging, and outer covering. The final assembly is also RoHS-certified. After the final assembly, you will get ready-to-use products.

  • Step 5. Shipping

    Usually we will apply the DHL shipping when we finish the turnkey PCB assembly. When you get the products, the perfect EMS service does not come to an end - you can always contact us if you have any concern, and we will also repair your PCBs and solve any other issues as well. And you are always welcome to keep a long term cooperation with us.
