    The whole process of PCB Assembly

    From Design to Finished Circuit Board: An In-depth Journey

    pcb testing
    1. Solder Paste Application:

    Solder paste is applied to the areas where soldering is required, usually using a stencil.

    2. Component Placement:

    Surface mount components are placed on the board using automated machines.

    3. Reflow Soldering:

    The board is heated in a reflow oven to melt the solder paste and create a solid connection between the components and the board.

    4. Inspection:

    The board is inspected for any defects or misalignments using visual or automated inspection techniques.

    5. Through-Hole Component Insertion:

    If there are any through-hole components, they are inserted manually or by machine.

    6. Wave Soldering:

    For through-hole components, wave soldering is used to solder the components to the board.

    7. Additional Inspection and Testing:

    Further inspection and testing are conducted to ensure the board meets all specifications and functions correctly.

    8. Cleaning:

    Any residue from the soldering process is cleaned off.

    9. Final Inspection and Packaging:

    A final inspection is conducted, and the boards are packaged for shipment.

    Frequently Ask Questions

    1. PCB assembly, or Printed Circuit Board assembly, is the process of populating electronic components onto a PCB to create a functional electronic device.

    2. What are the key steps involved in PCB assembly? The key steps in PCB assembly include PCB fabrication, component sourcing, solder paste application, component placement, soldering, inspection, and testing.

    3. What types of PCB assembly services do you offer? We offer a range of PCB assembly services, including surface mount technology (SMT) assembly, through-hole assembly (THA), mixed technology assembly, and package on package (POP) assembly.

    Answer: If you're looking for Prototype service, the min order quantity of PCBs is 5pcs but it's ok to have only 1pc of assembled board. If you use our Standard PCB service, there is no min order quantity limit.

    Answer: Absolutely. We offer two first article inspection options:
    Option 1: We send board images for your basic check and inspection. Once confirmed, we'll continue assembling your boards. All circuit boards will be shipped to you once completed.
    Option 2: We ship boards to your office for comprehensive inspection. Once confirmed, we'll continue the rest production.
    Generally speaking, Option 2 is more expensive and takes longer lead time than Option 1.

    A:Generally it takes 1-2 working days for us to quote assembly projects. Extra time will be required if you ask for large quantity. We'll send the quote to your email inbox once it's ready. First of all, please check your email inbox and junk folder for any email sent from us. If no email was found, please reach us at sales@circunex.com for assistance.
