SMT
Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs).
SMT Process Flow
Printing (Red gum/Solder paste) → Testing → Assemble (Firstly small parts then big parts: high-speed mounting and IC mounting) → Testing → Soldering (Warm reflow soldering) → Testing → Maintenance (Welding table and hot air dissoldering table) → Board cutting (Handmade or automatically)
Since the 21st century, the Chinese electronic information products manufacturing industry grows at a speed of more than 20%, which becomes the second in the worldwide from 2004.
