Modern SMT production relies heavily on fully automated reflow soldering systems to ensure consistent welding quality and high efficiency. Despite precise mechanical operation and intelligent program control,...
Reflow soldering is a core process in SMT PCB manufacturing, which directly determines the electrical performance and service life of circuit boards. Even with advanced automated soldering equipment, minor...
Through-hole (PTH) components are usually soldered to the PCB by wave soldering. However, here’s an alternative option – through-hole reflow soldering available for PCB assembly with PTH components.
Overview...
The terms SMT and SMD are often confused by beginners. However, they have distinct meanings:
SMT (Surface Mount Technology): SMT refers to the entire method of mounting components onto a PCB surface. It...
The components used in SMT are called surface mount devices (SMDs). They are compact with leads or contacts specifically for surface mounting. Key SMD types include:
SMD resistors: These passive components...
SMT assembly process is fully automated and precise. We ensure efficient and high-quality PCB production. The steps of the SMT surface mount technology process are below.
