Shenzhen ZhongFeng Electronics Co.,Ltd is a professional SMT manufacturer in China and we own 6 professional SMT lines (6 each of Panasonic HT121 and Yamaha YV100XG). To provide customers the best service and best quality, we ensure all SMD parts would be 100% SMT by machine.


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). An electronic device so made is called a surface-mount device (SMD). In the industry it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Both technologies can be used on the same board, with the through-hole technology used for components not suitable for surface mounting such as large transformers and heat-sinked power semiconductors.


An SMT component is usually smaller than the through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix of solder balls (BGAs), or terminations on the body of the component.


Because "surface-mount" refers to a methodology of manufacturing, there are different terms used when referring to the different aspect of the method, which distinguishes for example the components, technique, and machines used in manufacturing. These terms are listed in the following table:


SMp term Expanded form
SMD Surface-mount devices (active, passive and electromechanical components)
SMT Surface-mount technology (assembling and mounting technology)
SMA Surface-mount assembly (module assembled with SMT)
SMC Surface-mount components (components for SMT)
SMP Surface-mount packages (SMD case forms)
SME Surface-mount equipment (SMT assembling machines)
