PCBs are the backbone of every gadget, quietly making sure they work smoothly. <\/span>Once a PCB prototype is designed and fabricated, the next critical phase is PCB assembly (PCBA), which involves attaching components to the board to bring it to life. This article will delve into the evolution of PCB assembly, covering key technologies, advanced equipment, and the robust quality assurance systems that ensure high-quality PCBs.<\/span><\/p>\n

The <\/span><\/b>Evolution<\/span><\/b> of Component Mounting Technology<\/span><\/b><\/h3>\n

Through-Hole Technology (THT):<\/span><\/b> The dominant method in the 1980s. Component leads are inserted through holes in the board and soldered on the opposite side. Think of it like building with LEGO bricks.<\/span><\/p>\n
