Quick High Quality EMS PCB Circuit Board Assembly Turnkey Manufacturer

What is PCB Turnkey Manufacturer ?

A PCB turnkey manufacturer is a company that offers comprehensive services for the entire process of printed circuit board (PCB) production, from design and prototyping to fabrication, assembly, and testing. The term “turnkey” signifies that the manufacturer takes full responsibility for managing the entire PCB manufacturing process, providing a complete and ready-to-use solution to the client.

Services offered by a PCB turnkey manufacturer typically include:

PCB Design: The manufacturer may offer PCB design services, working closely with the client to create the circuit layout and design according to the client’s specifications.

Prototyping: Prototyping services involve producing a small batch of PCBs for testing and validation before full-scale production.

Component Sourcing and Procurement: The turnkey manufacturer handles the sourcing and procurement of all electronic components required for the PCB assembly, ensuring that the components meet the client’s specifications and quality standards.

PCB Fabrication: The manufacturer manages the fabrication of the bare PCBs, including the production of the circuit boards according to the client’s design requirements.

Assembly: The turnkey manufacturer handles the assembly of the electronic components onto the PCB, including surface mount technology (SMT) assembly, through-hole assembly, and any other required assembly processes.

Testing and Quality Control: The assembled PCBs undergo rigorous testing and quality control processes to ensure that they meet the client’s performance and reliability standards.

Logistics and Fulfillment: The manufacturer may also offer logistics support, including packaging, labeling, and shipping of the assembled PCBs to the client’s designated location.

Overall, a PCB turnkey manufacturer provides a complete end-to-end solution for PCB production, offering a seamless and integrated approach to meet the client’s PCB manufacturing needs.

EMS Circuit Board Assembly

EMS (Electronics Manufacturing Services) circuit board assembly involves the process of assembling electronic components onto a printed circuit board (PCB) to create a functional electronic device. This process typically includes the following steps:

Component Procurement: EMS providers source the required electronic components from suppliers based on the bill of materials (BOM) provided by the client.

PCB Fabrication: The PCB is manufactured according to the design specifications provided by the client. This involves etching copper traces, drilling holes, and applying solder mask and silkscreen.

Solder Paste Application: Solder paste is applied to the PCB using a stencil, which defines the areas where components will be placed.

Pick and Place: Automated pick and place machines accurately position surface-mount components onto the PCB using vision systems for alignment.

Reflow Soldering: The PCB with components and solder paste is passed through a reflow oven, where the solder paste is melted to create electrical connections between the components and the PCB.

Through-Hole Component Assembly: If through-hole components are used, they are manually or automatically inserted into the PCB and soldered using wave soldering or selective soldering machines.

Inspection and Testing: Automated optical inspection (AOI) and in-circuit testing (ICT) are performed to ensure the quality and functionality of the assembled PCB.

Final Assembly: Additional processes such as conformal coating, potting, and mechanical assembly may be performed depending on the specific requirements of the electronic device.

Packaging and Shipping: The assembled PCBs are packaged according to the client’s specifications and shipped to the designated location.

EMS providers offer a range of services beyond circuit board assembly, including design, prototyping, supply chain management, and aftermarket services. These services can be tailored to meet the specific needs of the client, from small-scale production to high-volume manufacturing.

SMT

The components will be mounted on the circuit board through SMT mounter, and online AOI automatic optical detection will be carried out if necessary. After testing, the perfect reflow furnace temperature curve is set to let the circuit board flow through reflow welding.

After the necessary IPQC inspection, the DIP material can then be passed through the circuit board using the DIP process and then through wave soldering. Then it is time to carry out the necessary post-furnace process.

1,The process of DIP processing is: putting in the hole →AOI→ wave soldering → cutting pin →AOI→ correction → washing → quality inspection.

2,After wave soldering, The products will be will scanned by AOI equipment to ensure that no error occurs.

Q: What files do you use in PCBA fabrication?

A: Gerber or Eagle, BOM listing, PNP and Components Position.

Q: Is it possible you could offer sample?

A: Yes, we can custom samples for your testing before mass production.

Q: How much time could I get the quotation after sent Gerber, BOM and test procedure?

A: Within 6 hours for PCB quotation and around 24 hours for PCBA quotation.

Q: How can I know the process of my PCBA production?

A: 7-10 days for PCB production and components purchasing, and 10 days for PCB assembly and Testing.

Q. Are my design secure when I send them to you?
