What is PCB Assembly?
PCB assembly is the process of populating a printed circuit board with electronic components and soldering them in place to create a functional electronic device. The process involves several steps, including:
- Solder paste application
- Component placement
- Reflow soldering
- Inspection and testing
RAYPCB utilizes advanced technology and skilled technicians to ensure that each step of the PCB assembly process is carried out with precision and accuracy.

RAYPCB’s PCB Assembly Process
Design for Manufacturability (DFM)
Before beginning the PCB assembly process, RAYPCB’s engineering team reviews your design files to ensure that they are optimized for manufacturability. This DFM review helps identify potential issues and recommends design improvements to enhance the reliability and performance of your PCB assembly.
Solder Paste Application
The first step in the PCB assembly process is the application of solder paste to the PCB’s surface. RAYPCB uses automated solder paste printers to ensure precise and consistent application of solder paste onto the PCB pads.
Component Placement
Once the solder paste has been applied, the PCB is loaded onto an automated pick-and-place machine. This machine uses advanced vision systems to accurately place SMT components onto the PCB’s surface at high speeds.
Reflow Soldering
After component placement, the PCB undergoes reflow soldering. The PCB is passed through a reflow oven, where the solder paste melts and forms a permanent electrical and mechanical connection between the components and the PCB.
Through-Hole Assembly
If your PCB design includes through-hole components, RAYPCB’s skilled technicians manually insert these components into the designated holes on the PCB. The PCB then undergoes wave soldering to secure the through-hole components in place.
Inspection and Testing
To ensure the quality and functionality of your PCB assembly, RAYPCB conducts thorough inspection and testing. This includes:
- Automated optical inspection (AOI) to detect component placement and soldering defects
- X-ray inspection to verify the integrity of hidden solder joints
- In-circuit testing (ICT) to test the electrical functionality of the PCB
- Functional testing to validate the performance of the assembled PCB
Final Assembly and Packaging
After inspection and testing, RAYPCB can provide final assembly services, such as mounting the PCB into an enclosure or integrating it with other sub-assemblies. We also offer custom packaging solutions to ensure that your PCB assemblies are protected during shipping and storage.
