The Surface Mount Assembly Process
PCB Preparation
The SMT assembly process begins with preparing the PCB, applying solder paste to designated areas to ensure proper component bonding.
Component Placement
Using precision equipment, components are carefully placed on the PCB according to the design specifications, ensuring accuracy and reliability.
Reflow Soldering
The PCB is heated in a reflow oven, melting the solder paste to create strong and secure connections for all components.
