PCB assembly process overview The PCB assembly process is a critical component of electronics production, particularly for surface mount technology (SMT). The process includes several key stages: applying solder paste to component pads using a solder screen, placing components on the board with a pick and place machine, and soldering the components using techniques like reflow soldering. Inspection, typically done through automated optical systems, ensures proper component placement and solder joints. Testing follows to verify the functionality of the assembled boards. Feedback from these stages is essential to detect and correct any manufacturing defects quickly. Typically, a prototype is produced and tested before proceeding to full-scale production to ensure quality and reliability.
