What is PCB Assembly? 

What is PCB Assembly?

PCB assembly (PCBA) is the process of mounting and soldering electronic components onto a bare printed circuit board (PCB) to create a fully functional assembled PCB. This involves placing components like resistors, capacitors, and integrated circuits onto the PCB, followed by soldering to establish electrical connections. 

PCBA is a crucial step in electronics manufacturing, transforming a circuit board design into a working electronic product. Choosing a reputable PCB assembly partner can help you get your PCB to market much faster and with fewer errors.

The PCB Assembly Process 

PCB Assembly Process
Step by Step Process of BGA PCB Assembly

We use a tried and trusted PCB assembly process to ensure consistent quality and reliability for every PCB. Here’s how it works.

  1. Design and Pre-Assembly

    Our PCB assembly capabilities begin with a thorough design consultation and review, where we collaborate closely with you to ensure that your designs are ready for manufacturing.

    We do a comprehensive design for manufacturing (DFM) check to optimize the assembly process and reduce costs. This includes a detailed review of the PCB design and sourcing components through client-provided materials, our extensive in-house inventory, or trusted suppliers. If PC board fabrication is required, we use our in-house manufacturing services to produce high-quality bare boards.

  2. Assembly Line Setup

    Our factory assembly line setups involve a strategic combination of automated and manual processes. Automated systems, such as pick-and-place machines, precisely position surface-mount components onto the board, while reflow ovens use controlled heat to solder these components in place.

    Manual assembly may be used for larger or more delicate components, as well as thru-hole components that need to be inserted and soldered by hand. Advanced equipment like wave soldering machines, automated optical inspection (AOI) systems, and in-circuit testing (ICT) further streamline the process, ensuring accuracy and efficiency for your PCBs.

    The specific configuration of the assembly line depends on factors like production volume, complexity of the PCB design, and budget constraints.

  3. Quality Assurance and Testing

    We take rigorous quality control measures throughout the process. This includes visual inspections to identify any defects or misplaced components, AOI to precisely check for soldering issues, and X-ray inspections to verify hidden connections.

    We also use ICT to assess component functionality and electrical connections. Functional testing verifies that the assembled PCB operates as intended by simulating real-world conditions and checking for proper electrical performance. These combined methods ensure PCBs meet the highest quality standards and perform reliably in their intended applications.

  4. Delivery

    Our dedicated team is committed to ensuring your order is processed and shipped promptly, with a focus on delivering on time, every time. We understand the importance of timely delivery and strive to exceed your expectations throughout the shipping process.

    Our lead time ranges from 4 to 25 days, depending on the complexity of your PCBs, the volume, whether you need hard-to-find components, and the materials you choose. Get an instant quote for the most accurate information on lead time.

Our Circuit Board Assembly Components

Printed Circuit Boards Assembly Technologies We Use 

Surface Mount Technology (SMT)

 Surface Mount Technology (SMT)

SMT is a method of electronic assembly where components are directly mounted onto the surface of a PCB, rather than being inserted into holes. This allows for smaller, more densely packed electronics with improved performance and reduced manufacturing costs.
Thru Hole Technology (THT)

Thru-Hole Technology (THT)

In this method, component leads are inserted through holes drilled in the PCB and soldered on the opposite side, creating a strong mechanical and electrical connection. Aka, Through-Hole Technology, THT is known for its reliability and is often used for components exposed to mechanical stress or high currents.

mixed technology assembly

Mixed-Technology Assembly 

Mixed-technology assembly combines both SMT and THT components on a single board. It leverages the advantages of each technology, enabling greater flexibility and optimization in the design and manufacturing process.
