What Is China SMT PCB Assembly?


China SMT PCB assembly refers to the process of mounting electronic components directly onto the surface of printed circuit boards (PCBs). Compared with traditional through-hole assembly, SMT offers:


  • Higher component density

  • Smaller board sizes

  • Greater electrical performance

  • Faster and more cost-effective production


This makes SMT the preferred method for industries like telecommunications, automotive, consumer electronics, and medical technology.
